The thermal efficiency.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the transverse sectional view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of fuel gas hot-blast stove furnace structure, including combustion chamber 2, the combustion chamber 2 are set with interior outside
Air duct 4, the interior air duct 4 are set with exogenous wind cylinder 6 outside, are formed between the outer air duct 6 and interior air duct 4 and are used for the wind that air flows through
Ring casing 15, the vane room 15 is interior to be equipped with ventilating smoke tube 5, and the lower end of the combustion chamber 2 passes through under lower flue room 3 and ventilating smoke tube 5
End connection, the upper end of the ventilating smoke tube 5 are connected with upper flue room 7, and the upper flue room 7 is connected with chimney 10.
Further, the spacing between two neighboring ventilating smoke tube 5 is equal and front-back staggered is arranged.
As shown in Figure 1, a kind of fuel gas hot-blast stove, including shell body 12, the shell body 12 is interior to be equipped with combustion chamber 2, described
The top of combustion chamber 2 is provided with gas burner 1, gas burner 1 at the same time on shell body 12, the shell body 12 with
It is the first vane room 16 between outer air duct 6, is vane room 15 i.e. the second vane room between the outer air duct 6 and interior air duct 4, it is described
It is the 3rd vane room 14 between interior air duct 4 and combustion chamber 2, the lower end of the first vane room 16 and the lower end of the second vane room connect
Logical, the upper end of the second vane room is connected with the upper end of the 3rd vane room 14；The upper end of the shell body 12 be equipped with into
Air port, forms room 8 against the wind between the shell body 12 and the upper flue room 7, the air inlet passes through 8 and first wind of room against the wind
The upper end connection of ring casing 16, the side wall of the shell body 12 are equipped with air outlet, the air outlet 13 and the 3rd vane room
14 lower end connection.
The air inlet is provided with two, and casing 11 is set with outside chimney 10, and described sleeve pipe 11 is connected with room 8 against the wind,
One of air inlet is formed between described sleeve pipe 11 and chimney 10, the shell body 12 is on the periphery of the gas burner 1
Place is equipped with another air inlet 9.
First vane room 16, the second vane room, the trend that the arrow on the 3rd vane room 14 is air, combustion chamber 2, logical cigarette
Arrow in pipe 5 is the trend of flue gas.
As shown in Fig. 2, in combustion chamber 2 by gas burner 1 fire air in the flame and combustion chamber 2 in air duct 4 into
The following current heat exchange of the 3rd backhaul of row.The 3rd backhaul that certain air carries out, the flow direction of air and the flow direction of flue gas can also be
Countercurrent heat exchange.
The indoor ventilating smoke tube 5 of second vane leads to the flue gas of combustion gas, and the wall heat of ventilating smoke tube 5 is formed with the indoor air of the vane
The following current heat exchange of second backhaul.The second backhaul that certain air carries out, the flow direction of air and the flow direction of flue gas can also be inverse
Flow heat exchange.
Outer air duct 6 and shell body 12 form the first vane room 16, and the air in it is the wall heat of external air duct 6, carry out the
The countercurrent heat exchange of one backhaul, the vane room replace existing insulation furnace wall materials alumina silicate fibre with air.
Flue gas moves towards：
Gas burner 1 is that burned flame enters in lower flue room 3 in combustion chamber 2, and the flue gas in lower flue enters back into
In ventilating smoke tube 5, the flue gas in ventilating smoke tube 5 rises to upper flue room 7, is finally discharged from chimney 10.
The trend of air：
Cold air imports top together with entering from the air inlet 9 above upper flue room 7 with the upper end of casing 11 on chimney 10
Air compartment 8 is preheated, and enters back into the first vane room 16 of outer air duct 6 and shell body 12 composition, the air then preheated is by first
Vane room 16 enters the second vane room that interior air duct 4 and outer air duct 6 form, air and the high temperature in ventilating smoke tube 5 of the second vane room
Flue gas is exchanged into the hot-air of medium temperature by following current, and the hot-air of medium temperature enters combustion chamber and interior wind by the top of the second vane room
The 3rd vane room 14 of cylinder composition, is exchanged by the heat following current produced with the thermal-flame of combustion chamber 2, generation high-temperature hot air and
Drawn by air outlet 13.
The furnace wall of the present invention uses ventilating and cooling, thus can greatly reduce the storage radiation loss of furnace body, makes furnace body itself
The thermal efficiency can effectively improve.
