Heat energy released in open hearth furnaces helps make more than 80 per cent of America's steel. In the process, much unused heat is discharged in the form of very hot gas from the open hearth exhaust.

Many kinds of waste heat boilers have been applied to the outlets of open hearths but their primary function has not been the efficient use of this excess heat energy. Rather, it has been their purpose to reduce the exhaust temperature so that the gas could be effectively cleaned in dust collectors prior to its discharge to atmosphere.

Combustion Engineering, experienced in the use of all kinds of marginal fuels and waste heat, and realizing the potential worth of open hearth gas as a power source, designed its Waste Heat Controlled Circulation Boiler - a truly efficient unit which makes maximum use of the tremendous energy in this gas. 

Utilizing C-E's Controlled Circulation principle, this boiler will produce greater quantities of steam from a given volume of gas - and at more efficient working pressures and temperatures. It will handle this highly corrosive exhaust routinely, and with minimum maintenance.

It can be tailored to fit difficult space conditions. In short, it is a dependable and efficient source of low cost power which, in the process of doing more work, effectively cools the gas so that it may be cleaned. 

Squeezing more work out of waste is a finely developed art at C-E. No matter its source, Combustion believes there is no such thing as waste heat - only wasted heat.
