Features and Air Distribution of Staged Chain Grate Combustion

Staged Chain Grate Combustion Features

The chain grate is a common boiler combustion device. Its combustion process uses staged combustion technology to improve combustion efficiency and reduce pollutant emissions. The features and air distribution of staged chain grate combustion are key factors affecting its performance.

The main feature of staged chain grate combustion is that fuel burns in stages on the grate. This design helps control the combustion process better and improves efficiency. Specifically, fuel starts at the front of the grate and moves backward gradually, passing through preheating, drying, ignition, combustion and burnout stages in turn. Staged combustion enables fuel to burn more fully, reducing unburned loss and improving boiler thermal efficiency.

Air Distribution

The air distribution of staged chain grate combustion is crucial to the combustion effect. A reasonable air distribution ensures that fuel at each combustion stage receives the proper air supply, supporting complete combustion and emission control.
