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.
