Abstract
The utility model relates to and discloses a combustion technology of an industrial boiler, and particularly discloses an environment-friendly industrial pulverized coal boiler capable of burning fuel gas in a blending way. The environment-friendly industrial pulverized coal boiler capable of burning the fuel gas in the blending way comprises a furnace wall, wherein a burner is arranged on the furnace wall; a primary air pipe is arranged inside the burner; an inlet of the primary air pipe is communicated with a gas supply device; a secondary air pipe is arranged on the outer side of the primary air pipe; one end of the secondary air pipe is communicated with a fan; the other end of the secondary air pipe extends into a hearth; the blast capacity of the fan can ensure the air volume of fuel in the hearth. According to the environment-friendly industrial pulverized coal boiler, primary air of the conventional burner is changed into natural gas carrying pulverized coal, and the secondary air volume of the boiler is increased to ensure the air volume required in the burning process of the boiler so as to ensure that the boiler provided by the utility model is adaptable to burning of coal gas; the natural gas is clean and efficient fuel, so that the emission of pollutants is reduced; by blending with the natural gas, the regulation load of the boiler is relatively quick and stable, so that the using amount of the pulverized coal is reduced and the cost for preparing the pulverized coal is greatly reduced.
Description
Technical field
The utility model relates to a kind of combustion technology of Industrial Boiler, particularly relates to a kind of environmental protection coal ash Industrial Boiler that can blending gas.
Background technology
Industrial Boiler is one of main heat energy equipment of China, existing Industrial Boiler fuel package oil scraper, gas and coal, domestic industry boiler be take fire coal as main, in coal-burning boiler of the prior art, be on furnace wall, to arrange a coal burner, coal burner is injected burner hearth with certain concentration and speed by coal dust preparation system respectively for the coal air mixture (wind) coming and the required Secondary Air of burning, under suspended state, realize the device of stable ignition and burning, but, this mode is difficult for catching fire while burning, and burning burn-off rate is lower.
Utility model content
For solving the problems of the technologies described above, the utility model provides and makes to be a kind ofly easy to burning, and effectively improve burn-off rate can blending gas environmental protection coal ash Industrial Boiler.
A kind of environmental protection coal ash Industrial Boiler that can blending gas of the present utility model, comprise furnace wall, on described furnace wall, be provided with burner, in described burner, be furnished with airduct one time, the import of a described airduct is communicated with feeder, and the outside of a described airduct is furnished with secondary air channel, and described secondary air channel one end is communicated with blower fan, the other end of secondary air channel extends in burner hearth, blower fan to air quantity, guarantee the air quantity of giving of burner hearth fuel.
Described burner is turbulent burner.
The outlet of described secondary air channel arranges swirl vane.
The beneficial effects of the utility model compared with prior art: because the import of an airduct is communicated with feeder, the outside of an airduct is furnished with secondary air channel, secondary air channel one end is communicated with blower fan, the other end of secondary air channel extends in burner hearth, blower fan to air quantity, guarantee the air quantity of giving of burner hearth fuel; Like this, change wind of original burner into natural gas and carry coal dust, and strengthen boiler secondary air quantity and guarantee the required air capacity of boiler combustion process, to guarantee to adapt under existing boiler load the multifuel combustion of coal gas, because natural gas is clean and effective fuel, reduced the discharge of pollutant, mix and burn natural gas and make the adjusting of the boiler fast and stable more of loading, reduced the use amount of coal dust, the cost of preparing coal dust is significantly reduced, by gas mixed burning, make boiler combustion gas and coal powder ignition burning complementation, accelerate speed of ignition, be conducive to the after-flame of fuel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the environmental protection coal ash Industrial Boiler that the utility model can blending gas.
Fig. 2 be the utility model can the environmental protection coal ash Industrial Boiler of blending gas in the structural representation of secondary air channel outlet.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail, following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Fig. 1-Fig. 2, a kind of environmental protection coal ash Industrial Boiler that can blending gas, comprise furnace wall 1, on furnace wall 1, be provided with burner 2, burner 2 is turbulent burner, in burner 2, be furnished with airduct 3 one time, the import of an airduct 3 is communicated with feeder 6, a wind in an airduct 3 is that natural gas carries coal dust, the outside of an airduct 3 is furnished with secondary air channel 4, secondary air channel 4 one end are communicated with blower fan, the other end of secondary air channel 4 extends in burner hearth, the outlet of secondary air channel 4 arranges swirl vane 5, blower fan to air quantity, guarantee the air quantity of giving of burner hearth fuel.
In the present embodiment, feeder 6 is prior art.
The present embodiment is because the import of an airduct 3 is communicated with feeder, the outside of an airduct 3 is furnished with secondary air channel 4, secondary air channel 4 one end are communicated with blower fan, and the other end of secondary air channel 4 extends in burner hearth, blower fan to air quantity, guarantee the air quantity of giving of burner hearth fuel; Like this, change 2 wind of original burner into natural gas and carry coal dust, and strengthen boiler secondary air quantity and guarantee the required air capacity of boiler combustion process, to guarantee to adapt under existing boiler load the multifuel combustion of coal gas, because natural gas is clean and effective fuel, reduced the discharge of pollutant, mix and burn natural gas and make the adjusting of the boiler fast and stable more of loading, reduced the use amount of coal dust, the cost of preparing coal dust is significantly reduced, by gas mixed burning, make boiler combustion gas and coal powder ignition burning complementation, accelerate speed of ignition, be conducive to the after-flame of fuel.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
