9T/H Automatic Brown Coal Fired Steam Boiler Travelling Reciprocating Step Grate
Achieve the following objectives:
1. Ensure the continuity and stability of garbage.
From the beginning of the garbage feeder to the exhaust of the ash discharge to the whole process of the slag discharge machine, should ensure the continuity and stability of garbage, and the height of the garbage layer in each area should be relatively stable, can not appear accumulation, blocking or a certain area layer is pulled empty.
2. Reasonable ventilation gap.
Garbage on the grate has uniform moving speed, reasonable distribution of air required for combustion, prevent local hammer head, resulting in air short circuit.
3. Excellent material.
Adopt alloy steel material grate, ensure the normal operation under high temperature, corrosion, easy to wear environment.
4. Flexibility of operation.
When the furnace is empty, manual intervention can be carried out and the grate is burned.
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.
