Oxidation Resistant Moving Coal Boiler Reciprocating Step Grate Wood Fired Chain Grate Stoker

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.
