Large Scale Chain Grate Stoker Bituminous Coal Fired Boiler With Coal Furnace Grates

Factory supplier bituminous coal fired boiler with coal furnace grates cross girder grate combustion device

Product Description

The coal furnace chain grates is a compact and technologically advanced layer burning device. Mainly by bracket, upper and lower rails, furnace chain, front axle assembly and rear rail, side seal, ash ashing device, coal hopper, front damper and duct. It can be widely used as a combustion equipment in large-scale boilers (which can be used for chain grate boilers with evaporation capacity of 20~90t/h) and various heating and drying equipments. Suitable for burning bituminous coal, lignite and peat. It can also be used as a combustion equipment for renewable fuels such as bagasse, firewood and rice husk.

The fuel of coal furnace grates should meet the following requirements

1. The maximum particle size of the coal block should not exceed 40mm, of which 0~6mm fine coal does not exceed 50% of the total, of which the coal content of 0~3mm is less than 25% of the total.

2. The moisture content of bituminous coal or lignite should be less than 20%, and the moisture content of 8~10% is the best choice.

3. The content of coal ash in coal combustion is between 10% and 30%, and the volatile component should not be lower than 20%.

4. The ash melting temperature of coal burning is less than 1250 ° C, and the coking property of the fuel is very low.

5. The low calorific value of coal combustion should be greater than 4226kcal/kg.

6. The primary air temperature used in this grate should not exceed 200 °C.
