Combustion Control (Automatic) Henry Furnace & Foundry Co. Cleveland, Ohio Miles Furnace Fan Division MILES FORCED DRAFT AND CONTROL UNIT MILES COMBUSTION, PRESSURE AND TEMPERA TURE CONTROL UNIT Reduces costs, maintains uni form steam pressure and tem perature and increases efficiency. Permits burning of cheaper grades of coal, slack, run of mine, buckwheat and rice. Miles Combustion, Pressure and Tem perature Control Unit is first, a forced draft unit, consisting of motor driven fan and pivoted damper actuated by steam pressure in the boiler, made in seven sizes to deliver air volumes as required and capable of overcoming various amounts of resistance. Second, it is an air pressure and control unit which effects an instant and minute control of the air volume and static pressure in response to pre-determined steam pressure or water tempera ture by means of the Miles Patented Air and Pressure Control Unit. A pivoted shut-off damper yields to air pressure from the fan to an open position, and yields also to pressure due to steam or water temperature to a closed position. These counteracting pressures actuate the damper to the exact position which con trols air volume and pressure under the grates and this in turn controls the fire. So delicate is it in operation that the steam pressure will maintain a steady heating load with a variation in pressure of not to exceed two ounces over an extended period. When a Miles Combustion, Pressure and Temperature Con trol Unit is installed, the chimney is eliminated as a draft producing factor. It becomes merely a vehicle for carrying off the products of combustion. Automatic control and me chanical force supply the correct amount of air for any and every condition. The Miles Control Unit may be installed on either side of boiler or furnace or in the rear. Only the Miles forced draft control has the patented graduated air supply feature which coordinates steam pressure and air volume to produce the required combus tion. This unique device is in action at all times when heat is required, and supplies air constantly so that ashes are kept cooled below fusing point--hence no clinkers. Write for complete information.

The piston rings hold the line pressure during the repacking operation. The ADSCO Piston-Ring Expansion Joint is available in all sizes in single and double slip design; semi-steel or cast steel bodies for all pressures up to 400 lb. and tempera tures to 750 F., with flanged ends or ends beveled for welding. Write for Bulletin No. 35-15. ADSCO Rotary Condensation Meter The ADSCO Packless Expansion Joint, U-Ring Type is based on an entirely new principle for controlling pipe expansion. The expansion element is a series of die-, formed "U-Rings" of stainless alloy steel, welded without transverse seams. The joint is installed with the element com pressed. Under full operating conditions, the element is in a neutral position, free from strain. Available with all steel body, fully enclosed element, for pressures to 400 lb. and 800 F., with flanged ends or ends beveled for welding. Write for Bulletin No. 35-50. ADSCO Vertical Steam Trap For measuring the steam condensation of a heating system or heating equipment. Used by District Heating Companies as a basis of charge for steam sold--institu tional groups for steam cost distribution-- and industrial firms for steam consumed in process work. Accurate within 1 per cent. Dependable. Compact. Reads directly in pounds of condensed steam. Furnished with semi-steel or aluminum body and cover in seven sizes; 250, 500, 750, 1500, 3000, 6000 -and 12,000 lb. capacity per hour. Write for Bulletin No. 35-80. The ADSCO Vertical Steam Trap, is a continuous flow, float type, trap with direct vertical inlet and outlet connections and an optional 90 deg. inlet connection. All working parts are mounted on the cover, all piping connections on the body. It has a reversible valve and reversible seat, giving a double life trap at no extra cost. The cover can be removed quickly and the mechanism serviced easily without disturbing the piping. Write for Bulletin No. 35-85A. 897
