Horizontal Boiler Grate Biomass Fuel Boilers With Reciprocating Step Grate
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.
Conclusion
1. MSW incineration is in line with the national strategy for sustainable development and is the development direction of MSW treatment in large and medium-sized cities in the future.
2. Compared with fluidized bed and rotary kiln incinerators, mechanical grate incinerators are more suitable for the characteristics of low calorific value and high moisture content of waste in China due to their complete and reliable technology, large capacity, strong adaptability to garbage and convenient operation and maintenance.
3. In view of the huge one-time investment in the construction of waste incineration plants, it is appropriate to make use of preferential loans from foreign governments and introduce advanced incineration technology, key equipment and management experience from foreign countries at the present stage. Domestic supporting funds shall be settled by local governments and waste incineration plants shall be operated and managed by enterprises.
