ZOZEN Boiler is good at designing different boiler systems and accessories according to different boiler room areas. This group of pictures shows the boiler condenser specially designed by ZOZEN Boiler, which is installed at the end of the boiler flue. The working principle is to use the waste heat in the boiler flue gas to heat the boiler feed water, which effectively reduces the heat loss and improves the thermal efficiency of the boiler system.
