Fixing respectively, another part is bottom in corresponding described coal bunker, with phase on corresponding described coal bunker two side
Answering installing hole to coordinate, corresponding described coal bunker is fixed on corresponding position on the furnace wall of described main burning furnace thorax outer side,
Described screw-type coal distributor water-cooled hot box is connected with boiler water cycle system.
The present invention compared with prior art, owing to igniting burner hearth and described main burning furnace thorax divides for described
Be not designed with ignite burner hearth coal feeder and one to four main burning furnace thorax coal feeder, described in draw
The vertical reflection of the described vertical reciprocating grate in the burner thorax chimney arch that ignites is i.e. main burning furnace thorax front wall,
Instead of arch wall before the boiler diaphragm type wall of existing main burning furnace thorax, described vertical reflection is ignited on chimney arch
Through hole instead of existing flue, and it provides the benefit that, described in ignite burner hearth and described main burning furnace thorax it
Between simple in construction, make described in the flue gas row in burner hearth that ignites little to described main burning furnace thorax resistance, described in draw
Burner thorax coal feeder and described main burning furnace thorax coal feeder realize from lateral respectively to described ignition furnace
Executing coal, coal non-resistance in thorax and described main burning furnace thorax, coal supply is smooth and easy, described screw-type coal distributor water
Cold shut hot tank stops radiation of burner hearth heat, it is to avoid overheated being undermined of corresponding described screw-type coal distributor is ignited accordingly
Coal in described screw-type coal distributor.
