SINGLE-CAN MULTI-CHANNEL LATENT HEAT RECOVERY HEAT EXCHANGER SYSTEM

摘要

PROBLEM TO BE SOLVED: To achieve energy saving by working heat efficiency raised through recovering of the latent heat. SOLUTION: A single-can multi-channel latent heat recovery heat exchanger system comprises a single-can multi-channel heat exchanger 22, a can body 31 provided in a combustion gas passage 25, a first heat transfer pipe 26 penetrating the can body 31, and a second heat transfer pipe 27 penetrating the can body 31. As a result of this constitution, up to the latent heat of water vapor contained in combustion gas is recovered.
