Description
Technical field
The utility model is related to boiler processing technique field, especially a kind of whirlwind secondary combustion-supporting hot-blast stove.
Background technology
Hot-blast stove turns into the product of electric heat source and conventional vapor power heat source, profit as thermal power machinery in many industries
The heat energy produced with fire coal improves heat utilization efficiency and hot working effect as medium and carrier.At present, traditional hot-blast stove mainly leads to
Air door air intake is crossed, is made because air intake is main combustion-supporting in coal-fired bottom in coal-fired lifting combustion efficiency, combustion process, Boiler pressure control is difficult
Degree is big, if air quantity is larger, can make coal-fired conflagration, burns insufficient, combustible is contained in cinder, coal-fired waste is caused,
If air quantity is smaller, make combustion-supporting effect relatively poor, the thermal efficiency is relatively low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of regulation and control air quantity, makes burning fully, the coal-fired wave of reduction
Fei Liang, improves combustion-supporting effect, the higher whirlwind secondary combustion-supporting hot-blast stove of the thermal efficiency.
To solve the above problems, a kind of whirlwind secondary combustion-supporting hot-blast stove described in the utility model, including in body of heater, body of heater
The flue that the ash-pit and upper of furnace body that the stove tooth of setting, stove tooth lower section are set are set, it is characterised in that：On the furnace body outer wall
Portion is provided with heat dissipating housing, and bottom is provided with the outside of wind-blocking board, the wind-blocking board and is connected with air-introduced machine by pipeline；The air-introduced machine and wind sheltering
Wind conveying pipe is connected between plate, the wind conveying pipe is connected with tornadotron；The tornadotron is set along the furnace body outer wall axial plane, and should
Tornadotron is provided with the air-supply mouth uniformly arranged；The air-supply mouth is set diagonally downward in the same direction, and forms annular wind path.
The wind-blocking board and the stove tooth set location flush.
The wind-blocking board is evenly arranged with fresh air inlet.
The air-supply mouth is provided with 3-5, and angle of inclination is located between 20-30 °.
The air-supply mouth is connected with the body of heater.
The utility model has advantages below compared with prior art：
（1）The utility model is provided with wind-blocking board due to furnace body outer wall, and wind conveying pipe is provided between wind-blocking board and air-introduced machine, will be entered
The air quantity separation entered, air quantity is regulated and controled, and makes fired coal combustion fully, the coal-fired wastage of reduction.
（2）The utility model is provided with tornadotron due to furnace body outer wall, and air quantity is rotated along tornadotron, and stove is transported to by tuyere
In vivo, to body of heater internal upper part coal-fired combustion-supporting, combustion-supporting effect is improved, makes its thermal efficiency higher.
Brief description of the drawings
