Description
Technical field
The present invention relates to a kind of vertical gas boiler, particularly relate to a kind of vertical three backhaul gas fired-boilers of central flame flame.
Background technology
On current market, the flue of the vertical type water heater boiler of supply is all arranged in lower portion thereof, flue space relatively narrower, combustion
Burner ejection combustion gas limited by flue area, flame can not be sufficiently spread out burning, cause combustion gas burnout the most completely just by
Discharging, heat-energy losses is bigger.It addition, traditional vertical gas fired-boiler mostly is fire tube list return structures, also exist flue gas flow shorter,
The problems such as smoke pipe heat exchange area is less, lateral fluid convection transfer rate is relatively low in smoke pipe so that the heat of fuel combustion release
Cannot be fully absorbed, thus cause that exhaust gas temperature is higher, boiler thermal output is on the low side.According to statistics, traditional vertical gas-fired boiler
Stove exhaust gas temperature, typically more than 200 DEG C, not only causes substantial amounts of energy waste, and environment is caused thermal pollution.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of vertical three backhaul gas-fired boilers of central flame flame
Stove.
The technical solution adopted in the present invention: a kind of vertical three backhaul gas fired-boilers of central flame flame, including cylinder, flue,
Burner, smoke pipe, spiral steel disc, collection smoke box, on turn smoke-box, under turn smoke-box, water inlet pipe, outlet pipe, smoke exhaust pipe, spring and the end
Seat, it is characterised in that: burner is positioned at vertical boiler cylinder top, and nozzle downwardly flue, flue is by cylinder and ellipse
End socket assembly welding forms；Strile-back type centered by the combustion system of flue flame, flame returns naturally along ellipsoidal head in flue
Turn, constitute the first backhaul of flue gas；Flue upper end turns smoke-box on connecting, and the second backhaul smoke pipe connection is upper and lower turns smoke-box；Collection smoke box
It is positioned at and turns above smoke-box, and by turning smoke-box under the 3rd backhaul smoke pipe connection.
Turning smoke-box under described is an annular housing, and its upper surface is annular tubesheet, and second and third backhaul smoke pipe is by welding
Being vertically fixed on annular tubesheet, its lower surface is ring plate, and bottom supports sealing of tube by four and is fixed on base.
Second and third return smoke circumference of cannon bone is circumferentially arranged around flue, the smoke pipe between two journeys on tube sheet according to equilateral triangle
Mode is arranged.
On turn smoke-box and collection smoke box be cylinder, its upper surface is ring plate, and burner is fixed on two annulars
The center of flat board, lower surface is annular tubesheet, respectively by second and third backhaul smoke pipe with under turn smoke-box and connect.
Being respectively provided with spiral steel disc in second and third backhaul smoke pipe, this spiral steel disc is slightly less than smoke pipe internal diameter by width
Steel disc distortion forms.
Compared with prior art, the invention has the beneficial effects as follows: one is that the vertical three backhaul gas fired-boilers of central flame flame will combustion
Burner is placed in vertical boiler top, adds the length of combustor, and fuel flame can be made fully to burn；Two is to use central flame flame
Combustion system, add the Radiant exothermicity of flue；Three is that the ellipsoidal head bottom flue can make thermal-flame freely
Revolution, decreases the loss of momentum of combustion gas；Four is that flue gas experiences three backhauls altogether, substantially prolongs the flow distance of flue gas, aobvious
Write the heat-exchange time adding flue gas.

Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
A kind of vertical three backhaul gas fired-boilers of central flame flame, including cylinder, flue, burner, smoke pipe, spiral steel disc, collection
Smoke box, on turn smoke-box, under turn smoke-box, water inlet pipe, outlet pipe, smoke exhaust pipe, spring and base.Burner is positioned at vertical boiler cylinder
Top, be fixed on collection smoke box and on turn the center of smoke-box, nozzle downwardly flue；Flue is by cylinder and ellipsoidal head
Assembly welding forms, its upper end with on turn the annular tubesheet of smoke-box by being welded and fixed；On turn the lower surface of smoke-box by the second backhaul
Smoke pipe with under turn smoke-box and connect, the lower surface of collection smoke box by the 3rd backhaul smoke pipe with under turn smoke-box and connect, second and third return smoke
Circumference of cannon bone is circumferentially arranged around flue, and the smoke pipe between two journeys is arranged according to equilateral triangle mode on tube sheet；Smoke-box is turned under described
Bottom by four support sealing of tube be fixed on base.
When gas fired-boiler runs, the thermal-flame that burner produces burns in flue and carries out a heat exchange with flue,
Through central flame flame by turn smoke-box and enter the second backhaul smoke pipe, after secondary heat exchange through under turn smoke-box and enter the 3rd return smoke
Pipe, is entered after three heat exchange in collection smoke box and is discharged by smoke exhaust pipe.Flue, smoke pipe are all immersed in stove water with turning smoke-box, are all
Flue gas and the heat-transfer surface of stove water, the healed water water inlet pipe from boiler side walls bottom enters, and the outlet pipe from top is discharged.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
