8ton/1.6MPa horizontal double drum reciprocating grate anthracite boiler steam boiler
Features
1. The granular fuel (wood of edge, bark, π, etc.), through the belt feeder hopper, before they are sent into the furnace into the grate let into the chamber by hydraulic device, at this point, the reciprocating grate will push forward and began to make grate surface formation even under fuel the fire of the bed.
Reciprocating grate is composed of an array of fixed grate and active grate, which is pushed by a hydraulic cylinder.
2. Grate has a level as Angle of 20 °, the fuel in the activity under the action of grate after moving gradually to the furnace, and disturbance in the combustion step by step to do.
Required for combustion air from the blower into the grate wind chamber, through the small hole on the link and wind slot into the furnace, in order to protect is combustion of oxygen, each room is equipped with damper wind, according to π adjusted with the quantity of air required for the combustion phase with the wind.
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.
