(Thermal) absorption heat pumps can be used for:
• Heat recovery through flue gas condensation
• Industrial waste heat utilization
Absorption heat pumps can increase the efficiency and economy of industry, waste combustion and heating (power) plants when waste heat flows at low and high temperature levels are available. In particular for feeding in to district heating grids close by.
Information about heat recovery through flue gas
Depending on the properties of the combustible, in most cases an extra yield of 5–10 % can be reached
For using the condensation heat of 45° C for district heating, a thermal driven absorption heat pump is needed. Thereby the district heating temperature of the return flow can be raised to 75–85° C. If higher temperatures for feeding in to the district heating flow are needed the existing boiler can raise the temperature to the desired level.
As shown in the example below, additional energy of 8 MWth can be won, which would otherwise escape through the chimney.
