Any exhaust gas stream with temperatures above 250 F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate. Typical examples include plant process heating, combustion air pre-heating, boiler feedwater pre-heating, and building heat.

t1 and t2 = temperature of hot gases before and after the W.H. boiler, °C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t2, the temperature at which the flue gases leave the boiler, may be reduced to ca. 50 K above the temperature of the water in the boiler.

Generally, the typical thermal efficiency of incineration boilers is as follows: for a waste heat boiler it is 63%, while that of the steam turbine generator combined system is only 30%. Therefore, when the effective thermal value of the solid waste is not high, it is usually used in the waste heat boiler to produce steam or recycle hot water.
