Abstract
A coal-burning gas boiler belongs to the technical field of heat energy engineering. A slit burner is installed between a gas generating chamber and a gas combustion chamber, the slit burner causes gas to enter into an inlet of the combustion chamber, and then the gas spreads around, igniting hole beams are installed at the lower portions of the gas generating chamber and the gas combustion chamber, the gas in the gas combustion chamber can be ignited at any moment by flame which comes from the gas generating chamber and gushes from the igniting hole beams, and the problem of deflagration is effectively resolved, meanwhile, air is provided twice, thereby the combustion is much complete, and the blackness and dust content of flue gas are decreased. The utility model is suitable for being used for heating and the production of industrial steam, domestic steam and drinking water.
Description
One, technical field
The utility model relates to the Thermal Power Engineering technical field, a kind of specifically coal-burning gas boiler.
Two, background technology
Now, China has made some big and medium-sized cities the regulation of inaccurate scatter fire of raw coal in succession, and this has just limited some boilers that still exceed standard at over-emitting black exhaust and smoke content.In addition, the ignition deflagrating of hot phenomenon because igniting is difficult to grasp opportunity, usually takes place in traditional gas generator (seeing " miniature boiler " book that boiler teaching and research room of Harbin Institute of Technology writes) when coal gas ignition.This is because coal gas generation instability occurs gas-fired sometimes and interrupts (because not having the incendiary source of " Chang Ming "), occurs the gas explosion accident easily.
" Industrial Boiler " introduced a kind of smokeless coal-burning boiler (patent No. 01211882) in the second phase in 2002, though normal combustion environmental-protecting performance index is up to standard, also exist operation easier big, and the problem of detonation takes place in igniting.
In addition, the gas exit of some gas burner is single, concentrates, and mixes inhomogeneously with auxiliary air, causes efficiency of combustion low, and operation easier is big, and poor stability.
Three, summary of the invention
The purpose of this utility model is to want to provide a kind of coal-burning gas boiler, and it can reach every index of environmental requirement, has solved the detonation problem, and, the efficiency of combustion height, operation easier is little, and security is good.
The technical solution of the utility model is as follows:
This gas burner is except having equally chimney, shell, convection heating surface, inner bag, water bridge, fire grate, the fire door etc. with traditional burner, there is gas generating chamber in central authorities at inner bag, the gas burner is positioned at around the gas generating chamber, the slit gas burner is between gas generating chamber and gas burner, and coal gas enters the gas burner by each gas entry of slit burner.Slit burner gas entry place is equipped with guard shield, can prevent the coal-fired gas passage that leads to the gas burner that stops up.The top of slit burner links to each other with water bridge, the bottom of gas generating chamber and gas burner is equipped with coal gas ignition hole beam, gas generating chamber and gas burner are run through in hole on the fire hole beam, the flame from generation chamber of from the hole, emerging, at any time the coal gas in the ignition combustion chamber is avoided detonation.Be equipped with moving grate in the gas generating chamber bottom, the bottom, gas burner is equipped with fixed grate.A blast orifice is arranged on ash storage chamber's wall, and primary air is supplied with gas generating chamber through moving grate, strengthens raw coal combustion, and auxiliary air is supplied with the gas burner through fixed grate, strengthens the burning of coal gas.Gas fume after burning is discharged by chimney after the convection heating surface heat exchange.
The utility model is simple to operate, only needs discontinuity to throw coal, and discontinuity is shaken moving grate ventilations, the ash that falls, timing scarfing cinder, deashing and got final product.The utility model can be at any time be coal gas ignition owing to assembled coal gas ignition hole beam, thereby igniting can not occur and be interrupted, and causes the ignition deflagrating of hot problem, can guarantee to light a fire and the safety when moving.Give wind apparatus owing to disposed secondary, make raw coal combustion efficient height, gasification rate is fast, and every environmental protection index is all up to standard, and compact conformation, and is simple to operate, and coal adaptability is wide.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that A-A of the present utility model is to cutaway view.
Five, the specific embodiment
From Fig. 1 and Fig. 2 as can be known, this gas burner is equipped with chimney 1 with the same top at stove of traditional gas burner, and body of heater is made up of shell 2 and inner bag 4, and convection heating surface 3 is arranged at 4 li tops of inner bag, is distributed with fire door 15 on the body of heater, clean-out door 16, shoot door 17.This gas burner has gas generating chamber 9 in the central authorities of inner bag 4, gas burner 11 is positioned at around the gas generating chamber 9, slit gas burner 6 is between gas generating chamber 9 and gas burner 11, and coal gas enters gas burner 11 by each gas entry of slit burner 6.The gas entry place of slit gas burner 6 is equipped with guard shield 8, can prevent the coal-fired gas passage that stops up.The top of slit gas burner 6 links to each other with water bridge 5, and the bottom of gas generating chamber 9 and gas burner 11 is equipped with coal gas ignition hole beam 14.Be equipped with moving grate 13 in gas generating chamber 9 bottoms, 11 bottoms, gas burner are equipped with fixed grate 10, and blast orifice 12 is arranged on ash storage chamber's wall, and sign 7 is a flame-observing hole among the figure.
Claims (2)
1, a kind of coal-burning gas boiler, comprise shell, inner bag, convection heating surface etc., there is gas generating chamber in the central authorities that it is characterized by at inside of boiler, and the gas burner is positioned at around the gas generating chamber, and the slit gas burner is between gas generating chamber and gas burner; The top of slit burner links to each other with water bridge; Be equipped with coal gas ignition hole beam in the bottom of gas generating chamber and gas burner; The bottom of gas generating chamber is equipped with moving grate, and the bottom, gas burner is equipped with fixed grate; A blast orifice is arranged on ash storage chamber's wall.
