Technical field
The utility model belongs to burning boiler equipment technical field, specifically a kind of coal-fired coal gasification normal-pressure hot-water boiler.
Background technology
At present, existing coal-fired coal gasification stove, using air intake twice, coal gasifies in gas generating chamber produces coal gas,
Gas burner is entered by crater, and the bore of crater is smaller, is easily accumulated on the fire grate for causing gas generating chamber bottom
Ash, so as to block crater, prevents coal gas from quickly escaping to combustion zone, causes boiler combustion speed to slow down and work(deficiency；It is another
Preceding fire tube and rear water pipe are respectively provided with aspect, combustion chamber, the endothermic effect of water pipe is not good, cause burning not to the utmost, energy-saving effect is not
It is preferable.
The content of the invention
The utility model in order to solve other coal-fired coal gasification boilers there is provided one kind combustion the problem of exerting oneself or go out fiery deficiency
Coal coal gasification normal pressure water boiler.
The utility model takes following technical scheme：A kind of coal-fired coal gasification normal-pressure hot-water boiler, including combustion chamber, coal gas
Generation room, desulfurizer and water tank, gas generating chamber bottom are provided with positive burning fire grate, and gas generating chamber passes through crater and burning
Room is connected, and is provided with anti-burn grate in combustion chamber below crater, and combustion chamber is some provided with vent, burning indoor location is seen
It is connected on the downside of longitudinally disposed fire tube, combustion chamber with gas generating chamber, gas generating chamber's connection flue gas case, flue gas case passes through superconduction
Pipe is connected with outlet flue, and outlet flue is connected by connecting cylinder with chimney, and chimney bottom is provided with spray equipment, spray-painting plant bottom
It is provided with reaction tank.
Further, outlet flue is also connected with blower fan.
Further, gas generating chamber top sets and installs by-passing valve on the bypass pipe being connected with chimney, bypass pipe.In combustion
By-passing valve is closed during burning, when stopping burning, by-passing valve is opened.
Further, high-temperature flame-proof wall is provided with combustion chamber.
Further, gas generating chamber side is provided with sealing firing door, sealing breast hole and positioned at just from top to bottom
Burn the sealing clean-out door below fire grate.
Further, combustion chamber top is provided with detection mouth, if bottom is provided with dry seal shoot door.
Further, spray equipment includes square spray chamber and the spray head being arranged on square spray chamber.
The water co-fire that coal is added after gas generating chamber, with gasification produces mixed gas, in the presence of blower fan, mixing
Coal gas is entered by crater with anti-burn grate fully to be burnt in the fire tube of combustion chamber, while the cinder below anti-burn grate exists
Also sufficient burning has been carried out in the presence of tertiary air, has been burnt again subsequently into fire tube, it is de- finally by spray equipment
Enter chimney after sulphur, whole process reaches smokeless, dustless environment protecting.
Compared with prior art, the beneficial effects of the utility model are：1st, will fully it be burnt after coal gasification, finally by spray
Drench desulfurization and be discharged into air into chimney, on the one hand reduce heat loss of imperfect solid combustion, on the other hand reach energy-conserving and environment-protective
Effect；2nd, preceding positive burning makes coal fully gasify, and the coal gas of generation increases fire grate burning area through anti-burn later, improves boiler thermal effect
Rate.
