1. Chain belt grate. The chain belt grate is a wide circular chain belt which is surrounded by and supported on the the front and rear axles via the chain wheels. At present, ZOZEN packaged chain grate steam boiler mainly adopts the large-block chain belt grate with a capacity of 1-20 tph.

2. Scale grate. The scale grate has many advantages. The obvious one is that there is less coal leakage. The scales can be replaced without shutting down the boiler. The ventilation is balanced, and the ventilation section is relatively small (6%). The chain grate bars only bears the stress or high temperature instead of both of them, which improves the working conditions of the chain grate.
