Lower section is additionally provided with the ash discharging gear for recycling fuel ash.
Further, the push plate is " rake " shape, and the water cooling plant is located in the concave surface of the push plate.
Further, the water cooling plant is water pipe and the band steel being connected with water pipe, and the band steel is equipped with some ventilations
Hole, the water pipe water inlet are connected with outer tank, and the water pipe water outlet is connected with boiler.It is cold when push plate works normally
Water extends fire grate service life into outlet pipe, playing the role of cooling down push plate；Water after heating enters boiler, and heat is whole
Utilize, improve the thermal efficiency of boiler.
Further, the burning inlet air plenum is equipped with the regulating device that can adjust air intake, so as to control entrance
The air quantity of ventilation hole, achievees the purpose that fuel completely burned.
Further, the fuel-feed bucket is equipped with high-low-position level-sensing device, can be realized according to the height of material position automatic
Charging, reduces manual labor.
Further, the top of the push plate is equipped with burner hearth, and fuel combustion is more advantageous to during burning.
Above-mentioned technical proposal is employed, the present invention has following beneficial effect：
1st, fire grate horizontal reciprocating movement of the present invention, allows particle ceaselessly to roll on grate surface and burns, until fully combustion
To the greatest extent, efficiency of combustion is improved to more than 95%；
2nd, the present invention uses water-cooled structure, does not use traditional alloy fire grate segment, significantly low from investment cost cost
In traditional fire grate, the more market competitiveness.
