Abstract

The utility model is a vertical type coal-making gas successive combustion boiler comprising a boiler body, a boiler tank, a boiler arch, a base, a gasificaton agent inlet and a removable grate, which is characterized in that: the boiler arch divides the boiler into a down coal gas chamber which is communicated with the inlet and a top radiation combustion chamber; a gas ignition gate is arranged between the radiation combustion chamber and the boiler body. A coke breaking removable grate is provided with a tower type coal gas generator and a vertical coal cylinder as well as a down-feed mechanical double-cylinder stoker connected to the vertical coal cylinder and a coal box at the center. The utility model is characterized in that: 1. the boiler is integrated with a gas furnace, coal gasification combustion is successive and clean, decoking is carried out by machine, coal of any quality is available and operation has no interruption; 2: the boiler is in triple-pass type whose flue gas process is as long as 4 to 6 meters and heating area is quite large. Its funnel temperature is less than 180 Celsius system, 200 to 300 Celsius system lower than that of similar products, thermal efficiency is as high as 80 to 86 per cent, combustion efficiency is larger than 94 per cent, saving 20 per cent energy, and soot density is smaller than 80 mg per m <3>, soot ringelmen number is smaller than grade one, SO2 and nitrogen oxides is lower than state standard.

Description

Vertical coal gas continuous burning boiler

Affiliated technical field:

The utility model belongs to boiler plant, and specifically, what it related to is a kind of vertical coal gas continuous burning boiler.

Background technology:

At present, traditional gas generator can be a coal gas with the raw coal solid fuel conversion continuously, is transported to clean combustion in other boilers, but itself can not do work in the while heat exchange; And existing hand burns semi-gas furnace or simple and easy gas burner (being commonly called as gasification furnace) on the market, though can heat exchange do work, because of artificial periodically coal, not only labour intensity is big, and has destroyed the boiler combustion operating mode, can not continuous heat supply work, serious is one burns one more clearly, intermitten service, and also the boiler coal adaptability is single, can only burn fat coal, can not burning inferior coal, cause volume of smoke to be discharged in the air, cause serious air pollution, environmental protection is not up to standard, wastes energy.

Summary of the invention:

The purpose of this utility model is at the problems referred to above, provides a kind of boiler and gas burner to be combined into one, the burning of coal gasification continuous cleaning, mechanical decoking, any ature of coal of burning, the vertical coal gas continuous burning boiler of free of discontinuities operation.

For this purpose, the utility model adopts following technical scheme: comprise boiler body [1], flue [2], chimney arch [3], base [4], gasifying agent import [5], the vertical coal gas continuous burning boiler that broken burnt moving grate [6] is formed, it is characterized in that chimney arch [3] is separated into flue [2] bottom gas generating chamber [11] and the top radiant [15] that links with gas exit [12], be provided with gas ignition door [16] between radiant [15] and the boiler body [1], the center of broken burnt moving grate [6] is equipped with tower gas producer [8] and vertical coal delivery cylinder [7], and raises mechanical twin-tub feeder [9] and add coal bin [10] with the following of vertical coal delivery cylinder [7] connection.

The interior gas exit of described gas generating chamber [11] [12] central upper installs turbulent burner [13] additional.

The middle part has been welded tangential parallel secondary wind [14] nozzle 6-12 in the described radiant [15].

The utlity model has following characteristics: 1, boiler and gas burner are combined into one, the burning of coal gasification continuous cleaning, mechanical decoking, any ature of coal of burning, free of discontinuities operation; 2, this stove is that three backhaul flue gas flows reach 4-6 rice, heating surface area is big, exhaust gas temperature is less than 180 ℃, low 200-300 ℃ of existing like product, boiler thermal output is up to 80-86%, and efficiency of combustion is greater than 94%, energy-conservation 20%, dust concentration is less than 80mg/m3, and flue dust blackness Lin Geman is less than one-level, and sulfur dioxide, nitrogen oxide are lower than national standard.

Description of drawings:

Fig. 1 is the utility model overall structure schematic diagram.

Among the figure: 1. boiler body, 2. flue, 3. chimney arch, 4. base, 5. gasifying agent import, 6. broken burnt moving grate, 7. vertical coal delivery cylinder, 8. the tower gas producer is 9. raised mechanical twin-tub feeder down, 10. add coal bin, 11. gas generating chamber, 12. gas exits, 13. turbulent burner, 14, tangential parallel secondary wind, 15. radiant, 16. gas ignition doors.

The specific embodiment:

Comprise boiler body [1], flue [2], chimney arch [3], base [4], gasifying agent import [5], broken burnt moving grate [6], chimney arch [3] is separated into flue [2] bottom gas generating chamber [11] and the top radiant [15] that links with gas exit [12], be provided with gas ignition door [16] between radiant [15] and the boiler body [1], the center of broken burnt moving grate [6] is equipped with tower gas producer [8] and vertical coal delivery cylinder [7], and raises mechanical twin-tub feeder [9] and add coal bin [10] with the following of vertical coal delivery cylinder [7] connection.

The interior gas exit of gas generating chamber [11] [12] central upper installs the turbulent burner made from silicomanganese vanadium material [13] additional.

The middle part has been welded tangential parallel secondary wind [14] nozzle 6-12 in the radiant [15], and preferred plan is 9.

The tangential angle of gas port of turbulent burner [13] is 35 degree, and it is consistent with tangential parallel secondary wind (14) direction of rotation angle, its effect is to use rotary centrifugal force to strengthen rotary combustion, improve fire box temperature, according to flame color, adjust air quantity, make the combustion chamber combustion gas mixing, reach completing combustion than more full and uniform.

During operation, the raw coal of particle 10-30mm is added in the coal bin [10], raise mechanical twin-tub feeder [9] under starting, make the coal-fired top tower gas producer [8] that is advanced to vertical coal delivery cylinder [7] by mechanical chain above, through stirring of rotation coal feeder, evenly be covered with at broken burnt moving grate [6] above the fire bed, start air blast or gasifying agent import [5] and give air quantity, make the raw coal low oxygen combustion produce coal gas, under suction function, pass through gas exit [12] and eddy flow gas burner [13], arrive radiant [15], the naked light that runs in the lighting door [16] takes fire, and, be that orange band blueness is optimal combustion state according to flame according to the tangential parallel secondary wind of the color adjustment of combustion flame [14] air quantity.Coal seam thickness is according to using thermic load, and adjustment adds coal bin [10] coal-supplying amount, makes its coal seam thickness even, the well-ventilated, and aerogenesis is vigorous, and burning is normal.Be in operation by observing the flame power, can judge when needing deashing, shake brokenly burnt moving grate [6], carry out the scarfing cinder ash disposal, favourable ventilation aerogenesis, it is more abundant to burn.
