A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration.Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from
The efficiency of generating power from waste heat recovery is heavily dependent on the temperature of the waste heat source. In general, economically feasible power generation from waste heat has been limited primarily to medium- to high-temperature waste heat sources (i.e., > 500 oF). Emerging technologies, such as organic

Obviously, all boilers of any kind are "heat exchangers" , but that is a not a complete term for engineering. A heat exchanger is almost always thought of as a fixed device that exchanges energy between fluids, doesn't mix the two product hot and cold streams (fluids or gasses) and doesn't usually require or expect phase changes in either side.
Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as 'high grade heat', contrasting to 'low-grade heat' available from the generator cooling circuits. This high temperature and flow makes it well
