Excerpt from The Improved Cochrane Steam-Stack and Cut-Out Valve Heater and Receiver: The Greatest Advance in the Art Since the Advent of Successful Open Feed-Water Heaters The utilization of exhaust steam offers immense possibilities for profit. The steam exhausted from an engine is still capable of delivering (at a temperature of 212 F., or higher, according to the back pressure) from 70 to 80 per cent. As much heat as when it left the boiler. If a large portion of the exhaust be used for heating or drying purposes, the power generated by the engines becomes a nearly costless by - product, or from another point of view, the heating is practically free of charge. Nevertheless in many plants exhaust steam is still wasted to atmosphere or is sent to a condenser, or electric current is purchased for power, while at the same time coal is being burned to produce live steam for heating purposes. Such wasteful practice is most often due to lack of familiarity with the best methods and means of utilizing exhaust steam. The use of exhaust steam for heating purposes not only offers the possibility of cutting the fuel bill nearly in half, but by conserving the pure condensed returns from the heating system and utilizing them as boiler feed it is in many cases possible to reduce the water bill by 80 per cent. And at the same time to cut off a large part of the expense of removing periodically from the boilers the scale that is deposited from most natural waters.
