Heat Pipe Heat Exchangers for Boiler Flue Heat

HEAT PIPE HEAT EXCHANGERS FOR BOILER FLUE HEAT RECOVERY. Heat Recovery from the flues of Industrial Boilers has for many years been effected by placing Economisers in the flue stack. Economisers first made an appearance onto boilers in 1845 to improve heat transfer for the products of combustion of large steam plant.

Experimental Study of Natural Gas Combustion Flue

Condensing boiler for flue gas waste heat recovery is widely used in industries. In order to gain a portion of the sensible heat and latent heat of the vapor in the flue gas, the flue gas is cooled by return water of district heating through a condensation heat exchanger which is located at the end of flue.

novel flue gas heat recovery system based on low

The heat and water recovery of the new system is not constrained by the dew point of the flue gas. It also lowers the requirement of the generation temperature due to vacuum regeneration. So in terms of heat recovery, the new system outperforms the traditional condensing system and the open-cycle absorption system by 28.3% and 23.1%, respectively.
