flue gas waste heat recovery


The heat within the boiler flue gas is recovered. A direct-fired lithium bromide absorption heat pump, using natural gas as the primary heat source, raises the temperature of the boiler's return water. This reduces the boiler's energy consumption and eliminates the visible white plume from the flue gas.   For example, a certain heating company recovers boiler flue gas heat using a direct-fired lithium bromide absorption heat pump unit. Approximately 3,023 kW of waste heat is recovered annually during 3,600 hours of operation.
