Biomass Furnace Reciprocating Grate For Steam Boilers Heating Of
Factory Fire Stoker
Features
1. A step-type horizontal reciprocating grate domestic garbage
incinerator mainly solves the problem that the existing chain type
mobile grate cannot effectively turn over the garbage, resulting in
incomplete combustion of garbage.
2. It includes pusher, hopper, chute, secondary combustion chamber,
furnace chamber, reburner, booster, grate assembly, furnace body
steel frame, slag outlet, etc. The grate is always a horizontal
reciprocating grate with ladder drop, and is divided into
preheating and drying zone, combustion zone, and burning zone in
the whole length of the grate;
A ladder drop is arranged between the dry area and the combustion
area grate;
3. The grate surface is connected by independent multiple grate
plates, adjacent grate plates are overlapped up and down, one row
of grate plates is fixed, and the other row of grate plates
reciprocates.
The furnace is automatically controlled, highly mechanized, highly
efficient and easy to operate.
It is mainly suitable for centralized incineration of household
garbage.
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.
