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.
