OF COMBINED ENGINEERING EXPERIENCE 28833 3 8.2 SQUARE FEET OF HEATING SURFACE per boiler horsepower The oil or gas burner generates the heat. The boiler's job is to use that heat by transferring it to the water in the boiler to generate steam. Obviously ... if the heating surfaces of the boiler are not of sufficient area to absorb all the usable heat much of it will be wasted up the stack. Generously proportioned heating surfaces have long been a distinguishing feature of all Kewanee Boilers. And in the Scotch rvpe used in rhe Kewanee-Ray Unit 8.2 square feet of heating surface are provided for each horsepower of the unit's nominal rating. Not only does this extra heating surface insure efficient transfer of the heat during normal operations, but it also pro vides sufficient surface to permit the boiler absorbing heat, even when fired, to produce 50% more than its nominal rated capacity.

Many tests prove the over-all efficiency of the Kewanee-Ray Unit. and an efficiency of 80% is certified. Actually, under nor mal "on the |ob" conditions, much higher efficiencies have been attained and maintained through a very wide firing range. The charts ar the left tell the story . . showing an over-all efficiency of some 81 `/2% ar 100% of rating and over 81% even when the unit is being operated at 150% of rating. The com paratively low temperatures of stack gases prove that an un usually large proportion of rhe heat is picked up by the water in rhe boiler and usefully employed in generating steam. J J 28834 OUTSTANDING FEATURES OF THE RAY BURNER GENERAL. DESCRIPTION The Rav Forced Draft Burner, with multi-stage air control, is designed as a burner unit for the Kewanee Scotch type boilers. This burner consists of a Ray direct or belt drive horizontal rotary oil burner with a dual pump and reservoir (of any de sired specification) mounted directly on the front plate of a windbox and a specially designed low pressure, integrated gas burner. Standard equipment includes all piping on the burner unn; electronic safeguard system; air safety switch; multi-stage air register ring; completely wired control panel; forced draft fan; and a windbox with integral refractory lining sized to project into the boiler furnace tube opening. A forced draft fan delivers air at constant pressure to the windbox which in conjunction with the air register ring pro vides a constant velocity type air stream to the combustion zone with high turbulence and a high turn-down ratio. A totally enclosed control panel contains all the necessary switches, motor starters, relays and electronic control unit providing easy accessibility in one compact unit. SIMPLICITY OF CONSTRUCTION The entire air control assembly may be readily removed ex posing the gas manifold ring and providing a manhole open ing of standard diameter for access to the combustion chamber ... as well as permitting easy inspection and adjustment of the air control unit. The totally enclosed control panel fits snugly alongside the boiler . . . taking a minimum of space. OTHER ASSEMBLIES The foregoing description applies particularly to the combi nation burner with full automatic oil burning unit and gas burner. The forced draft air control unit may also be assembled in the following combinations: (1) Integrated low pressure gas burner. (2) Rotary type, motor driven, oil burner for anv grade of oil and for manual, semi-automatic and fully auto matic operation. (3) Combination of gas unit with any of the oil burners listed. AIR REGISTER RING ASSEMBLY The design and position of the "Air Register Ring" with its constant velocity characteristics imparts a high degree of turbulence to the secondary air stream with a consequent rapid rate of combustion and a high turn-down ratio. Evidence of top efficiency is provided by the high percentage of CO; attainable. Air pressure in the windbox remains substantially constant throughout the operating range of the "Air Register Ring." HEAVY OIL OPERATION The Ray Forced Draft Burner is designed for fully automatic operation with any grade of oil. For heavy oil operation using c6 and some #5 oils, a unit combination heater, pump and circulating oil system is supplied with thermostatic controls interlocked through the burner controls in the control panel. 28835 5 9 GAS AND OIL FIRING ... with complete air COMBINATION GAS AND OIL BURNER The Ray combination Gas and Oil Burner consists of the Ray Forced Draft Horizontal Rotary Oil Burner and the Ray Forced Draft, integrated Gas Burner engineered in a single unit , . . Change Fuels at the Flick of a Switch The change in operation from one fuel to another is accom plished by a flick of a switch. No mechanical operation is necessary. The gas burner stays in position on oil firing and the oil burner stays in position on gas firing. HORIZONTAL ROTARY OIL BURNER The Ray Rotary Oil Burner, FD-AR, is designed especially for forced draff application. It uses a completely new and dif ferent principle of air control and introduction. This new method of air control coupled with the Ray Viscosity Valve and the dual pump and reservoir system . . . which scientifi cally controls the volume of oil to the burner, regardless of temperature .. . makes the Ray Forced Draff Burner the leader in its field for fully automatic. .. heavy oil operation at top effi ciency ratings. INTEGRATED GAS BURNER- The specially designed low pressure gas manifold ring en circles the air stream providing maximum aspiration and mix ing effect of the gas and air. The gas ring forms the throat of the forced draft air entrance and the gas is introduced through multiple drilled orifices around the throat. The secondary, high velocity, air stream passing over the orifices creates a suction which assists entry of the gas into the air stream ahead of the combustion zone. Thus the gas is not only pre-mixed, but high or low pressure gas supply may be utilized at top firing ratings and operation of the oil burner motor is not required. Equal gas distribution is assured by two gas inlets, one on either side of the manifold ring. 6 f )) 28836 # md fuel control MULTI-STAGE AIR CONTROL The furnace side of the FD-ARC burner shows the multi stage secondary air control vanes which impart a high degree of turbulence to the secondary air stream with a consequent rapid rate of combustion. Gas is introduced from the outer circle of vanes where it is pre-mixed with the air. The oil atomizing cup and the angular vane nozzle, which controls the primary air for oil burning, are down in the center of the air register assembly. Operation: The Forced Draft Fan delivers the air to the windbox at sub stantially constant pressure. Secondary air is then metered by the Ray patented "Air Register Ring." Primary air, also fur nished by the Forced Draft Fan, is monitored through the oil burner fan and angular vane nozzle . . . thus the pressure gen erated bv the Forced Draft Fan is added to that of the fan on the burner for increased nozzle velocity and better oil atomi zation. Efficient ratio of air to fuel is constantly maintained at all firing rates by the Ray Automatic Control System. This con trol system is operated by a fully modulating motor, position ing the interconnected Ray Oil Viscosity Valve, gas butterfly valve, primary atomizing air valve and secondary air register ring, regulating the fuel and air as the load demands. VISCOSITY VALVE AND DUAL PUMP ft RESERVOIR SYSTEM The Ray VISCOSITY VALVE is a patented, exclusive fea ture of all Ray fully automatic heavy oil burners. It supplies the burner with a scientifically controlled volume of oil which is unaffected by changes in temperature or viscosity of the oil and maintains a controlled firing rate which varies only to meet changing load requirements. The greatest advantage of the Rav VISCOSITY VALVE over similar devices for controlling the oil flow is that it ac complishes so much without any moving parts ... it does not adapt itself to changes in viscosity; it makes the oil adapt its rate of flow to the needs of the burner. In the valve itself, there are no moving parts, no mechanisms to wear out. An integral part of the Ray VISCOSITY VALVE system is the Ray Dual Pump and Reservoir. The dual, gear type pumps are submerged in a reservoir of oil with the primary pump drawing oil from the storage tank to the reservoir and the secondary pump delivering a constant volume of oil to the VISCOSITY VALVE. By allowing air to separate from the oil and be exhausted back through the return line, the reser voir eliminates the danger of flame instability and failure re sulting from leaky suction lines or oil vapor formation. 28837 7 STEAM SPACE Amply proportioned to assure large re serve of dry steam now extends through boiler shell.

Ask am user, engineer, architect or heating or power con tractor they will tell you that in their field Kewanee Boilers lead, as they have for nearly a century. That reputation has been earned by the true quality which is built into every Kewanee product. Kewanee puts more into its boiler so the owner gets more from them. From drafting board to finished product . . the experience and skill of Kewanee engineers has been continuously applied. First in the design and proportioning of all parts to be certain that each will work properly with all the others. Then by closely watching the boilers in process of construction and fabrication. And finally in tests that insure boiler performance as planned. Yes there is MORE ENGINEERING in each Kewanee. MORE MATERIAL . . . the generous proportioning of all parts and the use of heavier steel plate not only insures more reliable ruggedness but equips each Kewanee to handle large overloads easily and efficiently. MORE LABOR examine any part of any Kewanee. No tice the faultless seams and welds, the smooth finish of cast ings, and the care with which each part is firmly fixed in its place. This extra care requires more labor, but it puts some thing extra in the boiler. And back of all these is MORE ENGINEERING . . . a knowledge and "know how" which can only be obtained bv many years of experience. These are the things which have built an enviable reputation for Kewanee . . . they are the "extras" you buy with every Kewanee Boiler that can't be converted into terms of dollars and cents. Easy to clean . . . easy to inspect There are two sides to every boiler and every part of the Kewanee is easy to get at1 The large hinged doors at the front swing open, clear of the burner, providing easy access to the fire tubes from the front for ease of cleaning and inspection. The entire back cover plate, constructed in two patts, can be completely removed for access to the rear combustion cham ber and the rear end of fire cubes. Or the rear combustion chamber can be cleaned through the dean-our door at the bottom, without removing the cover plate. 28841 n 5 COMPARE THESE QUALITY FEATURES MEMIER ACCESSIBLE WATER SURFACES The water surfaces are just as easy to inspect and dean as the fire tubes. A large manhole through the top of the boiler and adequate washout openings, properly placed, give ready access to the waterways. Fire tubes are widely spaced to make the outside of the tubes easily accessible. This spacing further frees and speeds-up the circulation of the water. Carbon deposits inside the fire tubes ... or scale lining the waterways ... provides an insulation that makes it difficult for the heat to get through. So an unkept boiler... a dirt)' boiler ... can't produce steam with full efficiency. But with a Kewanee both fire tubes and waterways are easy to get at... an important feature that helps keep the boiler operating as it was built to perform. GAS TIGHT FLUE DOORS WITH QUICK OPENING U-BOLTS Leakage of heat through flue doors, or other openings, causes efficiency losses of considerable importance in many boilers. Kewanees are made with permanent gas-tight doors .. . ground to a precision fit and sealed by a riveted woven asbes tos tape gasket. Place a thin piece of tissue paper in the open ing; shut the door, tighten the U-bolts, and it's impossible to pull the paper out without tearing it. Try it sometime your self... you'll find the doors on Kewanee Boilers fit that closely. Note, too, the thick insulating lining on the inside of the door that prevents warpage and provides a positive gas-tight fit throughout the life of the boiler. T 1 A.S. M.E. CODE CONSTRUCTION... 8. B.l. RATED In construction Kewanee Boilers meet or exceed all the rigid code requirements of the American Society of Mechani cal Engineers; as well as those of a well-known independent boiler inspection and insurance company. The Kewanee-Ray Units are rated in accordance with the provisions of the Steel Boiler Institute Code... yet are certi fied to produce at least 50% more than this nominal capacity. In addition, Ray Burners are built to rigorous standards to comply with all requirements of the Underwriters' Labora tories, Inc., and bear its seal of approval where required. 4 12 28842 EL8ERT M. palmer VICE PRESIDENT Kewanee-Ross Corporation DIVISION OF AMERICAN RADIATOR & STANDARD SANITART CORPORATION BULLETIN 2374 BRANCHES & SALESMEN - Subj: Kewanee-Ray Boiler-Burner Unit KEWANEE, ILLINOIS Tan. 22, 1954 With this bulletin we are pleased to enclose the following: 1. Kewanee-Ray Boiler-Burner Unit Catalog......... 1031 2. Temporary Trade Price Sheet, effective Jan. 4, 1954, covering boiler for Kewanee-Ray Boiler-Burner Unit, high pressure steam only. 3. Temporary Trade Price Sheet, effective Jan. 4, 1954, covering boiler for Kewanee-Ray Boiler-Burner Unit, low pressure heating, 15# steam, 30# water. 4. Covering letter to Architects and Engineers. 5. Covering letter to Jobbers (Classifications 1 and 3). 6. Covering letter to the Trade. We are not going to distribute the trade price sheets to the Trade or Jobbers at this time - you will note that in the letters released to them we have suggested that they contact you for price information. When the Trade and our Jobbers do become familiar with these units, we expect to give them published trade price sheets as we do on our other products. The Jobber's preferential is 10% based on the published trade price and before the addition of surcharge. Again, the hard and ingenious work of two top engineering forces in their respective fields -- Kewanee and Ray -- have produced a unit that we know meets all requirements of e quality product and is one of the best and most practical in the field. Again, may we suggest that you first get acquainted with the Ray representative in your area. Have him tell you all the salient features of their equipment. At least know the main superior factors of the Ray firing equipment. Secondly, point out the superior features of Kewanee Boilers to him. You will sell the boiler assembly. They will sell the firing equipment. We want to emphasize the importance of having both organizations out in the field endeavoring to get the Kewanee-Ray Boiler-Burner Unit specified. From previous experience we have found both the architect and engineer especially receptive to our specifications ... which is the outstanding factor attributing to the increasing success we have had in the boiler-burner unit field. Some engineers desire to fully detail their specifi cations. You will have material to hand them. Others desire to use a brief EWANEE BOILERS AND WATER HEATERS ROSS HEAT EXCHANGERS AND SURFACE CONDENSERS 28843 Bulletin 2374 p/2 Jan. 22, 1954 Subj: Kewanee-Ray Boiler-Burner Unit specification just mentioning the number, rating, pressure and type of unit. This can be done from the catalog data. The designing engineer, architect or contractor may desire to estimate the cost of the boiler plant. You now have your trade price sheet for the Boiler of the unit. The prices on all boilers to be used as boiler-burner units must be figured from the enclosed price sheets because they contain certain special items. We will forward you prices on the various Ray firing assemblies to be used for estimating purposes only, just as soon as possible. When the job comes up for actual bidding, you will quote as you regularly do to the trade or jobber, and you will have the Ray representative quote on his equipment. Specification sheets on both the boiler and the burner will be in your hands in the near future. EMP KEWANEE-RQ5S CORPORATION 28844 FOR YOURSELF NO. 1 WELD. X-RAYED AND STRESS RELIEVED The dependability of welded joints, for both high and low pressure boilers has reached new heights. But to be even surer and safer, cverv welded seam that carries the full operating load in high pressure Kewanees is radiographed with a high voltage X-ray machine to detect possible blow holes due to gas pockets, faulty fusion or any other defects. Test specimens are then stressed to destruction to be certain that the strength and ductility of all joints meet specifications. And in a modern Stress Relieving Furnace. Kewanee Boilers for high operating pressures are heated to a temperature of 1200 F then allowed to cool gradually. All fusion welded joints are thus completely annealed and any locked up stresses relieved. PUMP AND RECEIVER If specified, a Boiler Feed Unit is included with the boiler shipment. This equipment is not attached to the boiler skids, allowing installation at the most convenient place. There are 13 sizes for units of 39 to 304 hp . . . 125 and 150 lbs. wp. The single pump unit is shown. Duplex Units, consisting of 2 pumps and 2 motors mounted on a single chassis wich the tank, are also available.
