Industrial Reciprocating Grate Stepping Grate Boiler ISO9001 Certification

ISO9001 certification manufacturer stepping grate boiler for coal steam boiler

Description

One of the main features of a slanted reciprocating grate that is distinct from a chain grate is the relative motion between the grate and the coal. When the active grate is pushed backwards, some of the new fuel is sent to the upper part of the already burnt coal. When the active grate returns to the front, it brings back some of the fuel that has been burned to the bottom of the unburned fuel. The same is to heat the new coal. This kind of ignition condition is similar to that of the hand-fired furnace, and the effect is better than the chain grate. The coal is continuously squeezed on the reciprocating grate, and the coal is slowly tumbling, so that the coal seam is loosened and leveled, which is conducive to combustion. Therefore, it is higher than the general boiler. In addition, compared with the chain grate, the reciprocating grate does not require high granularity of bituminous coal, so it is more suitable to use low quality coal or firewood as fuel.

Features

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.
