YOU USE LESS POWER... SAVE CONDENSER WATER .. . SAVE UPKEEP COST S For large refrigeration systems, NIAGARA gives you a choice between a battery of condensers (that may be cut on or off with the load) or a high capacity condenser that saves space. Both have the patented "Duo-Pass" and "Oilout" that remove superheat and keep the system free of oil. Results: you save one-third or more of power cost and upkeep expense. Niagara Patented Balanced Wet Bulb Control gives lowest head pressure operation automatically. Wtitt for Bulletin 111. NIAGARA BLOWER COMPANY Over 35 Yean' Service in Induiiriil Air Engineering Dept.

Dr David A Keys, Chairman, Project Coordinating Committee of Atomic Energy of Canada, officially opened the contention and power show with an ad* dress, Industrial Applications of Atonic Energy. He stated that Canada's atomic scientists are abreast of developments in both the United States and Great Britain, that her expert! are sticking to their predictions that, it will be ten years before useful electric power can be de veloped from atomic reactors. Atomic power plants are feasible on s commer cial basis. Keys said, but considerable research will be needed at the pilot plant level before industry can use them. Papers presented at the technical ses sions included: Turbulent Suspension Burning of STaste Fuels by Otto de Loi> enxi of Combustion Engineering, By product Power by John Aikman of Canadian Celanese Ltd, Reducing Flue Dust Emission by Charlea If Marks of Bituminous Coal Research, Steam Turbinej'by D F Abel of Canadian General Electric Co, and Place of Steam Power in Canada by E H Davis, consulting en gineer. Abel reviewed the- development and application of steam turbines from their earliest days down to the present and then took a look at the future. He said that the trend toward higher tempera tures and pleasures will continue snd will extend itself right down to mechani cal-drive turbines. Today the metallur gist holds the key to this progress, Abel said, since it is practically impos sible for the design engineer to improve performance until he's given improved materials with which to work. The steam turbine now holds the spot light in the power field, and everyone Is wondenDg what will bo revealed next. During the last five years, pressures have risen from 1600 to 4500 pii, tem peratures from 1000 to 1150 F. Single shaft, 3600-rpm units will soon generate 200,000 kw as compared with the 100,000-kw units of five years ago. Thera appears to bo no limit. The steam tur bine industry anticipates that it even-, tually will build units capable of deliv ering half a million kw.
