ZOZEN Boiler Energy Saving Device - Economizer

Boiler economizer is an important energy saving device in boiler system. Its principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in the smoke. Economizer can be divided into cast iron economizer and steel tube economizer according to different manufacturing materials. This gallery displays the cast iron economizer produced by ZOZEN Boiler. The cast iron economizer is mostly used in boilers with pressure ≤2.5 MPa. If the pressure exceeds 2.5 MPa, the steel tube economizer should be adopted.
