4200KW CDZH Moving Grate Coal Fired Hot Water Boilers is suitable for wood chips, wood brick, wood pellet and coal as fuel. It is one dual fuel boiler and do not have strict requirement for fuel size. DZH moving grate coal fired boiler is widely used in smaller steam capacity requirement.
Feature of 4200KW CDZH Moving Grate Coal Fired Hot Water Boilers
1) High Working Efficiency: Adopt arch tube sheet and currogated flue gas tube for drum making, make sure high heat transfer efficiency and full load working. This design also avoid dust deposition in flue gas tube and solve the tube sheet crack problem.
2) Best Welding Quality: Welding position adopt mechnical processing and high temperature area special technique process, which make sure welding quality and long life span
3) Better Water Circulating Design: eliminate the Slough at boiler drum, better ciruclating effect and avoid boiler drum bottom swell.
4) Suitable for Multi-Fuel: Suitable for brown coal, bituminous coal,wood brick, wood pellet, wood chips and industry waste.
5) Compact Structure and Easy to Install: build foundation, connect to electricity and pipe, install valve. Then it can work.
