PEOPLE Boiler Efficiency - energy

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

Waste Heat Recovery - Energy

Work potential based on Carnot efficiency for energy conversion (mechanical or electrical) was also evaluated in order to better compare waste heat with different exhaust temperatures. Based on a 77°F [25°C] ambient reference temperature, the work potential of all the waste heat studied is about 600 TBtu/yr.
