Waste Heat Recovery - US Department of Energy

The heat pump receives heat from a low­temperature source and rejects it at a higher temperature. The heat pump uses waste heat plus an additional 0.22 million Btu of electrical energy to provide 1 million Btu of useful heat, while the boiler requires an input of 1.25 million Btu to provide 1 million Btu of steam heat.

Waste Heat Recovery Methods And Technologies - Chemical

Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW, and hence reduces boiler fuel requirements. Flue-gases are often rejected to the stack at 30 to 70°C higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by ~ 1% for every 22°C reduction in fluegas temperature.

Waste Heat Recovery for Power Generation | Industrial

Waste Heat Recovery for Power Generation. Power can be produced by using a steam cycle, an organic rankine cycle, or the KALINA process. The low temperature level of the waste heat in cement plants (200 400 °C) limits the efficiency to a maximum of 20 25%. However, 25 to 30% of plant's power demand can be met through generating power from waste heat.
