- Steam, hot water, hot water, hot air can be produced free of charge by taking advantage of the heat of the hot smoke gases thrown in the busses in industrial facilities and cogeneration facilities.
- For example, at the cogeneration plants, the flue gas temperature to be poured into the diesel and gas engines is 400 … 500 ° C;
- In cement plants at 400 …. 600 ° C, steam boilers and hot oil boilers at 250 …. 350 ° C and so on, flue gas temperatures can be reduced by 120 …. 180 ° C according to the fuel type.
- A 20 ° C reduction in flue gas temperatures provides approximately 1% fuel savings. Waste heat boilers are manufactured in smoke tube or water pipe types to save energy (and therefore money).
