30-50T/H Brown Coal Fired Cast Boiler Spare Parts Grate Biomass
Burner Fire Grate Industrial Reciprocating
Air-cooled cascade reciprocating grate incinerator heat center
1. The heat energy center of wood-based panel enterprises is
industrial waste, sawing wood, slicing, bark and sawdust produced
in the production process of enterprises
And sand powder as the main fuel combustion by the furnace heat
energy (such as hot air, hot oil, steam and other heat carriers) to
provide enterprises with the production of heat energy supply
equipment
2. Air-cooled step-type reciprocating grate furnace is the main key
equipment of thermal energy center, and the combustion furnace (YGW
reciprocating grate) produced by our company
Square box burn wood waste organic heat carrier furnace) combustion
system adopts hydraulic inclined pushing reciprocating grate, the
cooling system of air cooling for grate, grate piece adopts 1100 ℃
high temperature resistant alloy steel refined but become,
applicable to waste wood and straw waste combustion, sanding powder
using air cooling nozzle with high pressure fan into.
3. Four nozzles are fired in the tangential direction to form a
vortex flame in the furnace to increase the combustion journey and
turbulence of the sanding powder, so as to completely burn out the
sanding powder, and at the same time will bring in the sand
particles (sanding light belt off) sedimentation in the adiabatic
furnace chamber, to increase the rear dust removal effect
The advantage of a grate furnace is that it does not require
pretreatment of waste.
The technology is mature and widely used in foreign countries. Its
disadvantages are as follows:
1. Furnace row must be heat-resistant, during long-term continuous
operation, the thermal stress must remain unchanged, so that the
furnace row material requirements, and the processing of the
furnace row is complex, because the furnace row needs to rotate,
low reliability and high energy consumption constitute its
problems.
2. Because of the complex composition of garbage, it is difficult
to keep the common grate moving uniformly in the whole grate and to
burn uniformly and completely.
3. It is difficult for the grate to adapt to refuse incineration
with a wide range of moisture content, because the waste with high
moisture content needs a wide dry area, which makes it difficult
for the waste with high water content to be completely burned.
4. More difficult to control furnace temperature, waste slag at
above 1000 ℃, and 1050-1100 ℃ in the softening and viscous state,
become the special corrosive substance, may be corrosion of furnace
wall, at the same time under high temperature condition Nox
concentration increased.
5. It is difficult to realize large-scale furnace and remove HCI
gas in the furnace. Special equipment and HCI removal equipment
need to be installed in the tail, which increases the investment
cost.
6. It is necessary to set up special sewage treatment facilities
for refractory landfill leachate.
7. The grate furnace is not only complex to manufacture, high cost,
but also large in size and covers a large area.
