Description

Direct-fired semiwater gas boiler

One, technical field

The utility model belongs to boiler manufacturing technology field, is specifically related to a kind of semiwater gas boiler.

Two, background technology

The fuel availability of coal-burning boiler is low, and the gasification process is slow, chamber temperature is low, and intensification is slow and taken away a large amount of combustible volatile, makes carbon residue be difficult to after-flame.In combustion process, not flammable mineral grey matter is put in " grey clothing " to carbon in the coal charge, and " grey clothing is gradually thick " makes its very difficult ingress of air, causes imperfect combustion, wasted a large amount of energy.Since on fire slow, chamber temperature is low, has discharged a large amount of combustible volatile and sulfur material, contaminated air.

Because there are above-mentioned all deficiencies in direct-fired coal-burning boiler, people have developed gas boiler.It is that coal is added in the gas generating chamber substantially that gas boiler on the market integrates, and makes coal under the condition of high temperature anoxic, and coal gas takes place, and gas is directly sent in the burner hearth burnt then.This boiler must set up gas generating chamber, and adds the heat of cold water device control gas generating chamber.Excessive in order to prevent coal gas, must sealing between fire door and the doorframe, it is explosion-proof and prevent that coal gas is excessive to establish water seal tank below boiler; Explosion proof door must be set to prevent gas explosion above the combustion chamber.Need establish two cover supply air systems in addition, coal gas usefulness for taking place in a wind, and secondary wind gives gas to burn and uses.This boiler cost height, volume is big, auxiliary device, device are many, be difficult for to move, be difficult for installing, most critical be not easy to operate, have explosion danger.

Three, summary of the invention

The purpose of this utility model provides a kind ofly can burn coal, and semiwater gas and improve the direct-fired semiwater gas boiler of efficiency of combustion can burn again.

Semiwater gas (semi-water gas) is steam and air (or oxygen-enriched air) to be blown in the gas generator together with the anthracite of red heat or coke effect and the coal gas that produces is the mist of water gas or producer gas.The burning semiwater gas can improve fuel availability, reduces pollution emissions.

The technical solution adopted in the utility model is: direct-fired semiwater gas boiler comprises stove seat, shell, flue and fire grate, it also comprises hydrate liquid case and vaporizer, vaporizer is circular, is installed in above the stove seat, the shell bottom, and its periphery and shell inwall join; Hydrate liquid case is installed in the body of heater top, and the pipeline of vaporizer through being connected with control valve, check-valves is connected to the hydrate liquid case of upper of furnace body; The vaporizer both sides have the blast pipe that reaches below the fire grate downwards, two exhaust pipe lower part connecting branches, and arranging on the arm many has the bank tube of spray orifice to constitute jet grid.

The utility model adopts the ring-shaped gasification chamber, uses the stove endogenous pyrogen, imports jet grid after producing the saturated vapor with medium composition, is mapped in the fervid coal charge by spray orifice, quickens gasification, oxidation obtains water-gas, promptly produces i.e. burning, and a stove is finished two flow processs.

Five, the specific embodiment

Direct-fired semiwater gas boiler comprises stove seat 1, shell 4, flue 5 and fire grate 2, ashpit 9 is arranged respectively on stove seat 1 and the shell 4 and throw coal charge door 10, it also comprises hydrate liquid case 8 and vaporizer 3, vaporizer 3 is circular, be installed in shell 4 bottoms above the stove seat 1, vaporizer 3 peripheries and furnace shell medial surface join; Hydrate liquid case 8 is installed in chimney next door, boiler top, and the pipeline 8-1 of vaporizer 3 through being connected with control ball valve 8-2, check-valves 8-3 is connected to the hydrate liquid case 8 of upper of furnace body; Vaporizer 3 both sides have the blast pipe that reaches below the fire grate 2 downwards, and two exhaust pipe lower parts have hinged arm, and a plurality of evenly distributed bank tubes are arranged on two arms, and the fumarole that has even row to establish on each bank tube, the bank tube that arm and its are arranged above constitute jet grid 3-1.The arm of jet grid 3-1 and each bank tube are below fire grate, and be parallel with fire grate, the spray orifice on the bank tube up, the spraying of coal charge in the combustion chamber; When not needing coal charge gasification, oxidation, but closing control ball valve 8-2 rotates to stove seat inwall, the position vertical with fire grate with jet grid.In the hydrate liquid case medium and the water that ethanol, methyl alcohol, tween, distilled water etc. are mixed with is housed.

Fire grate 2 of the present utility model is upper and lower two-layer combined type fire grate, and lower fire grating 2-1 is fixed on the stove seat 1, and upper fire-grating 2-2 is placed on above the lower fire grating 2-1, and the rib of upper and lower fire grate does not coincide, and the handle that is connected to the body of heater outside is arranged on the upper fire-grating 2-2.There is circular hole at the center of lower fire grating 2-1, and there is downward projection at the center of upper fire-grating 2-2, and this projection is inserted in the circular hole of lower fire grating 2-1.Move the handle upper grate and can do reciprocal plane motion, make on the fire grate 2 the solid carbon displacement collision of carrying, strip off grey clothing on the coke with this.

In upper of furnace body middle funnel 6 is arranged, middle funnel 6 is a truncated cone, hang over below the exhaust opening of upper of furnace body, there is the adapter body 7 that connects chimney at the exhaust opening place, take on the body 7 and have dog-house, in the middle funnel sulphur removal material is housed, the sulphur removal material has calcium oxide etc., can produce reaction with the sulphur in the flue gas.
