An SRU flue gas waste heat recovery system can be installed with any natural gas or LPG fired power burner boiler or heating unit. When the heating unit is required to operate on oil the flue gases will have to be bypassed from the waste heat recovery unit. Flue gas recovery systems have been used around the world for over 20 years.

Waste heat recovery - SlideShare

Oct 16, 2016· Waste heat recovery. Hot gases pass over one end of the heat pipe, causing the working fluid inside the pipe to evaporate. Pressure gradients along the pipe cause the hot vapor to move to the other end of the pipe, where the vapor condenses and transfers heat to the cold gas. The condensate then cycles back to the hot side of the pipe via capillary action.
