2021-3-14 · A new type of heat pump for residential systems is the absorption heat pump, also called a gas-fired heat pump. Absorption heat pumps use heat as their energy source, and can be driven with a wide variety of heat sources. For more information on these specific types of heat pumps, go to: Air-source heat pumps; Ductless mini-split heat pumps
If the heat is used for power generation, it can save up to half of the electricity used in the clinker process. Heat-recovery opportunities, however, are closely tied to the basic structure of the kiln: an advantage of the preheater, precalciner kilns is that waste heat is used in the first two stages.
Waste heat is generated through the everyday usage of electrical machines, large boilers units or cooling systems. The rate for lost energy through flue, exhausted gas or general process heat is around 15 to 20 %. But through a waste heat recovery system can up to 90% of the exhausted heat be recovered.
The heat demand of the passive building has been calculated considering the heat recovery from ventilation and the efficiency of the recuperator. The average annual cost of heating of the energy-efficient building is PLN 4, 715, while of the traditional building – PLN 14, 115, i.e. three times as much.
Economic evaluation was based on the assumed discount rate of 5% and on the expected plant operation time of 25 years. combustion in a recovery boiler. Syngas cleaning and sulfur recovery have
