C W Hackett When the above note arrived, the ther mometer was scrambling into the upper 90's and our first reaction was that the heat had gotten us, or, perhaps, Reader Hackett. Then we noticed a clipping from the Sa vannah Morning News attached to the letter. Sure enough, the headline said "twelve b.t.u.'s have conference." What with the heat and all, we were almost ready to believe that the Btu's in Georgia were getting together, perhaps to unionize for better working conditions. Our hopes of a real technical scoop were dashed by the lead paragraph of the story, however. There it was made plain that the B.T.U.'s referred to' were department leaders in the Baptist Training Union. Regretfully we canceled hastily formed plans for stopping the presses to make way for an epoch-making announce ment and went hack to trying to avoid the effects of the over-abundant Btu's in New York's summer atmosphere. Incidentally, Reader Hackett, we're ready to take on any assignment dealing with garden-variety BTU's, but we wouldn't even try to "cor rect" the Baptist variety. No sir!--Ed.

It was in their shops that the photos for Walter's picture story on motor re winding (pp 118-123) were taken-- in the course of an actual job. Before joining Maintenance, Walter saw quite a bit of the world, beginning with China, where he took mechanical and electrical degrees at Harbin Poly Walter Prise technic. He .'also has a BSEE from the University of California. In 17 years of practical experience he has worked for utilities and shipyards in various parts of the U.S., spent some time on radar development and served as a consultant. Walter is active in AIEE's rotating-machinery committee, serving as a member of the dc subcommittee. He's also national publicity chairman for National Industrial Service Assn and acts as consulting editor for Electrical Construction and Maintenance.. These assign ments testify to his interest in writing, which he lists as one of his hobbies. The other--more fun, we think--is sailing. AIR CONDITIONING, in one form or another, is a pet subject with Tommy Barrett. In what might be called its straight form, it plays a hig part in his job as building superintendent of the world-famous Waldorf-Astoria. Backed by 25 years of experience with marine and stationary equipment of all kinds, Tommy directs an engineer ing force of more than 100 in the never-ending task of maintaining and .improving the equipment of his "city within a city." For some slants on how he does it, see p 116. . T J Barrett Tommy is also neck-deep in that large-scale form of air-conditioning known as smoke prevention. As national director of NAPE's air-pollu tion program, he has spark-plugged their contributions to development of sound local ordinances and to the encouragement of correct operat ing methods that attack air pollution at its source. ART EDITOR is the title you'll find beside Charlie Marschalek's name on Power's masthead. Because it falls short of accurately describing his con tribution to your magazine, we'd like to tell you about his work. In modem technical publishing, we don't "write" articles and then "illus trate" them. From the beginning, we plan word elements (headlines, cap tions, text) and picture elements (photos, drawings, charts) to form a meaningful whole that gets across ideas in the fastest and easiest fashion. C F Marschalek In this planning, Charlie, a specialist in organizing material on the printed page, consults with our technical editors every step of the way from idea, to "visual" or layout, and to the finished article. Charlie likes to spend out-of-office hours hiking and taking color photos. Right now he's vacationing in Europe, doing both. - 5 3 Look for these three STRONG low-maintenance fea tures inthe STRONG 80 Series Inverted Bucket Trap: 1.

Muriatic acid is now produced in mechanical fur naces. At best, there is still some gas leakage at the doors of the furnace and to prevent this from escaping we have installed collecting hoods under suction from a 'large fan with the HC1 gas ab sorbed in water. We get a partial return on our investment, since we take the very weak acid produced and put it over the absorption towers in the main system. Our gas loss to the air has been reduced by at least 90% or to less than one-half ton per day. The salt cake produced on the me chanical furnace is at high temperature and it would gas readily if we did not condition it before it leaves the system with what we call a cooler-degaser. It is a water-cooled screw conveyor that receives the hot, gassy salt cake from the furnace and cools it down rapidly to a point where it won't give off any more gas. Since putting this-in opera tion there is not a trace of gas or odor in the salt cake discharged from the cooler and it can be transported to storage without contributing in the slightest to air contamination. APSPAA paper. No number. The Mechanical Type Dust Collector for Spreader Stokers. 1By Philip F Best, The Thermix Corp. To envision a dust collector ideal for a spreader stoker, you must consider all dimensions of the dust emission, par ticularly those factors that influence performance of the collectors. Ash quantity ordinarily expected to go to the stack is the first. It is influ enced by the percent of ash in the coal, percent of combustible in the ash, grate . areas, furnace volumes and whether or not partial or total reinjection of the ash catch is contemplated. From 20 to 50% of the ash in the coal leaves the furnace in flue gas, depending upon burning rate of the particular furnace. Entrained with this ash will be 10 to 85% com bustible. Second dimension to be considered is size. From many tests by both research organizations and industry, it is pretty well established that size of flyash from spreader stokers varies from 25 to 50% minus 325 mesh. This same size range will probably bold whether or not there is reinjection. You can logically assume, however, that with reinjection the dust would be finer than without reinjection. The combustible in the ash ranks as D/rect/ons for ordering papers on p 752 Ii. lI f { f\ fj 1I l fI |i i. t r POWER AUGUST 1952 A WITH ADVANTAGES Leading Utilities Are Switching to KAYLO HEAT INSULATION A Better Basic Material. Kaylo Heat Insulation is hydrous calcium silicate -- a revolutionary material (not glass) developed after many years of research. Proved in thousands of field installations, it combines to a high degree the most desirable physi cal qualities of heat, insulating materials. Outstanding in Performance. Kaylo Heat In sulation has a wide effective temperature range --up' to 1200 F.--thus eliminating the need for com bination coverings in nearly all operating conditions. The material's unique cellular structure, composed of countless sub-microscopic dead-air spaces, provides high insulating value. It remains efficient and stable through years of service. Even when saturated with water,.Kaylo Heat Insulation retains about 85% of its strength. It regains its normal strength and insulating efficiency after drying. It has high flexural strength, compressive strength and resistance to impact and abrasion. Workmen can walk on insulated equipment without causing breakage. Easy to Apply. Kaylo Heat Insulation's' light weight makes it extremely easy to handle and apply. The ease with which it can be cut and fitted simplifies application--saves time on the job. Break age during installation is usually negligible. The ma terial is non-irritating to the skin and non-toxic. With the widest .selection of sizes and shapes in the industry, Kaylo Heat Insulation reduces the number of pieces required per job. Get the complete details.

This is not greatly important to the dust collector manufacturer, except as it affects size and quantity of dust, but it is definitely important to the stoker manufacturer and to the ultimate customer. These three considerations deal with the dust itself and the problems pre sented by its quantity and quality. There are other considerations, how ever, both physical and economic. APSPAA paper.

In most home boilers .this job will not be simple. What is more, to get 100% efficiency in, anything is like catching the proverbial, will-of-the-wisp. - But for the process industries and especially those employing baking ovens with warm air heating, the device seems highly promising. To work, the catalyst, must be raised to a temperature of 500. F. So for the starting-up stage, some: form of special, catalyst-preheater needs' to go in. Once oxidizing begins though, and given a gas stream fairly rich in hydrocarbons, the unit will sustain com bustion of room temperature gases. For every Btu per cu ft in the exhaust gas ' the catalyst will raise stack temperature 55 F,. and through recirculation this : heat can be reclaimed. .
