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.
