Cast Iron Coal Furnace Grates Customized Moving Boiler Parts Simple Operation

ISO9001 certification manufacturer stepping grate boiler for coal steam boiler

Features

1. Reciprocating driving grate furnace is referred to as reciprocating furnace.
2. The grate is composed of movable and fixed grate plates arranged in phases.
3. There are various types of grate plates, but the ladder type inclined grate driven by machinery is widely used.
The grate is made of cast iron.
4. Its combustion condition is similar to that of the chain furnace, and segmenting air supply, brick arch and secondary air can also be adopted to improve the combustion condition.
5. Due to the good dialing performance, coking coal and low-grade coal with high moisture and ash content can be burned. The smoke effect is better.
6. Due to the poor cooling condition of the exhaust furnace sheet, it is not suitable for burning anthracite with low volatile matter and high carbon content.
Limited by the size of discharge furnace structure, this kind of furnace is mostly used for small capacity boilers under 40t/h.

Advantages:

1. The height of the horizontal reciprocating grate is lower than that of the inclined reciprocating grate, which can effectively save the area of ​​the boiler room, thereby reducing the installation and use cost of the user.

2. In the horizontal reciprocating grate, through the operation of the equipment, the fuel layer (coal layer) can be uniformly covered on the grate, and at the same time, compared with the conventional grate, the internal connection of the grate is relatively tight, and there is no air leakage. The area, so that the wind speed through the coal seam is relatively uniform, the content of coal ash after combustion is significantly reduced.

3. The coal seam is wave-shaped on the horizontal reciprocating grate, and its surface area is 30% to 50% larger than the horizontal surface area of ​​the grate. Therefore, the flow rate of the flue gas leaving the surface of the coal seam is relatively slow, so that the amount of fly ash is reduced compared with the chain grate. 10%.

4. The combustion efficiency of the fuel in the horizontal reciprocating grate is relatively high. Therefore, the furnace temperature is high and the combustion is relatively sufficient, so that coals with strong coking properties can be burned. It can also burn cohesive biomass fuel, which greatly improves the adaptability of the grate to fuel.

5. The fuel preparation and dust removal equipment is simple, the overall cost, low operating cost and simple operation management.
