The anti-gravity clean coal-fired boiler is mainly applied to coal-fired boilers.
Description
Technical field
The utility model relates to a kind of boiler, is specifically related to a kind of antigravity clean combustion of coal boiler.
Background technology
Along with social development, people are more and more stronger to the protection consciousness of environment, thereby energy saving and environment friendly boiler also more and more is subject to people's concern and welcome, China is the production of coal and uses big country, industrial coal and coal consumption of living use amount are very large, continually developing and utilizing along with coal, the coal resources of China are fewer and feweri, therefore the thermal efficiency that improves and take full advantage of coal is extremely to need the problem solved, transformation by boiler structure can make coal burn fully, improve the thermal efficiency of coal, reduce the exhaust emission of flue dust, environment purifies air, thereby reach the purpose of energy-conserving and environment-protective, the boiler structure of prior art is varied, most boiler structures is unreasonable, coal burning is insufficient, produce a large amount of flue dust in combustion process, Dark smoke billows, the soot emissions severe overweight, do not meet the requirement that national energy-saving reduces discharging, not only wasted resource but also polluted environment, researching and developing energy-efficient less boiler is very important.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of simple and reasonable for structure, sufficient combustion, the antigravity clean combustion of coal boiler that efficiency of combustion is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: antigravity clean combustion of coal boiler, comprise: body of heater, described body of heater inside is provided with burner hearth and ashes chamber, described burner hearth is provided with feeding port, the ashes chamber is provided with cleaning door, be provided with fire grate between described burner hearth and ashes chamber, described body of heater is sandwich, middle cavity is the air distribution chamber, is provided with a plurality of aid distributing pipes on the hearth wall of burner hearth, and described burner hearth is connected with the air distribution chamber by aid distributing pipe, described air distribution chamber also is provided with air inlet, and described ashes also are provided with outlet flue on chamber.
Described fire grate is water-cooled grate.
Be provided with blower fan on described air inlet.
The beneficial effect that the utility model compared with prior art had is: the utility model adopts the ashes chamber to set out mouth, burner hearth arranges aid distributing pipe, coal on fire grate is carried out to overheavy firing, because outlet flue is arranged on the ashes chamber, the flue gas that coal combustion produces flows downward in burner hearth, combustible component in coal is fully burnt, fundamentally eliminated the phenomenon of over-emitting black exhaust, ignition temperature is low, effectively reduced flame temperature, reduced the generation of NOx, and avoided the deposition of dust, reduced the thermal resistance effect of dust stratification at heating surface, greatly improved efficiency of combustion, reduced the corrosion of dust stratification to boiler simultaneously, extended the service life of boiler.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is body of heater, and 2 is burner hearth, and 3 is the ashes chamber, and 4 is feeding port, and 5 is cleaning door, and 6 is outlet flue, and 7 is fire grate, and 8 is the air distribution chamber, and 9 is aid distributing pipe, and 10 is air inlet.
The specific embodiment
As shown in Figure 1, antigravity clean combustion of coal boiler, comprise: body of heater 1, described body of heater 1 inside is provided with burner hearth 2 and ashes chamber 3, described burner hearth 2 is provided with feeding port 4, ashes chamber 3 is provided with cleaning door 5, be provided with fire grate 7 between described burner hearth 2 and ashes chamber 3, described body of heater 1 is sandwich, middle cavity is air distribution chamber 8, is provided with a plurality of aid distributing pipes 9 on the hearth wall of burner hearth 2, and described burner hearth 2 is connected with air distribution chamber 8 by aid distributing pipe 9, described air distribution chamber 8 also is provided with air inlet 10, on described ashes chamber 3, also is provided with outlet flue 6.
Described fire grate 7 is water-cooled grate.
Be provided with blower fan on described air inlet 10.
When the utility model is specifically used, close feeding port 4 and cleaning door 5, and sealed, body of heater 1 is sandwich, middle cavity forms air distribution chamber 8, be provided with a plurality of aid distributing pipes 9 on the hearth wall of burner hearth 2, burner hearth 2 is connected with air distribution chamber 8 by aid distributing pipe 9, ashes chamber 3 is provided with outlet flue 6, blower fan is by air distribution chamber 8 like this, aid distributing pipe 9 enters in burner hearth 2, coal on fire grate 7 is carried out to overheavy firing, the flue gas that coal combustion produces flows downward in burner hearth 2, outlet flue 6 by ashes chamber 3 flows out, combustible component in coal is fully burnt, fundamentally eliminated the phenomenon of over-emitting black exhaust, ignition temperature is low, effectively reduced flame temperature, reduced the generation of NOx, and avoided the deposition of dust, reduced the thermal resistance effect of dust stratification at heating surface, greatly improved efficiency of combustion, reduced the corrosion of dust stratification to boiler simultaneously, extended the service life of boiler.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make various variations.
