Made of titanium-magnesium-aluminum alloy material, plate heat exchange method, change the heat exchange structure of biomass hot water boiler, no ash will accumulate on the heat exchange plate, and the heat exchange efficiency will not be affected by ash accumulation. It has good thermal conductivity, which is conducive to improving the heat exchange efficiency of hot water boilers, making the heat of flue gas fully exchanged with circulating water, and saving energy.Widely used in manufacturing, enterprises, hotels, bathing centers, hospitals, schools…
