Because the product structure of a gas water tube boiler of the prior art is unreasonable, the thermal efficiency is low, and the combustion system adopts a blower type burner, the noise is loud, the electric consumption is more, the boiler has the danger of deflagration or explosion, the utility model provides a gas hot water boiler with high thermal efficiency, simple structure, secure running, low cost and automatic control. The utility model comprises an outer package, a furnace wall, a furnace pipe, a base seat, a water inlet, a water outlet, a smoke exhaust mouth, pressurized elements, a burner and an automatic control system. The pressurized elements are composed of four header tubes arranged in the font, the rear, the upper and the lower parts, a 180-degree elbow joint connecting the upper and the lower header tubes, and a finned water pipe connecting the front and rear header tubes. The burner is an atmospheric type burner, which is composed of a gas pipe, a nozzle, a distorted burning pipe, a small firearm, and a gas valve.
Description
Technical field:
The utility model belongs to the forced circulation water-tube boiler, relates in particular to a kind of gas-fired water heating boiler of automatic control.
Background technology:
Because environmental requirement is more and more higher, heating boiler turns to the burning clear energy sources by fire coal gradually, as burning light oil, natural gas, artificial coal gas, liquefied gas, fire damp, biogas etc.At present, domestic oil-burning gas-fired boiler generally adopts internal combustion fire tube boiler (shell boiler), and its structure inner bag is a corrugated flue, and heating surface is the screw-type smoke pipe.The shortcoming of this multitubular boiler is: fire tube stops up easily, and the thermal efficiency is low, the operating cost height, and flue boiler tube complex structure, steel consumption is many, the cost height.
Also have a small amount of combustion gas water-tube boiler to come out in recent years, because unreasonable products structure, the thermal efficiency is lower.Combustion system adopts air blast burner in addition, and not only noise is big, power consumption is many, and needs furnace purge, and is unclean as purging, and the danger that detonation or blast take place is arranged.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming of prior art, provides that a kind of thermal efficiency height, simple in structure, security of operation, cost are low, the gas-fired water heating boiler of automatic control.
The utility model takes following technical scheme to realize its purpose.
A kind of gas-fired water heating boiler, comprise: external packing, furnace wall, burner hearth, base, water inlet, delivery port, exhaust opening and pressure parts, burner, automatic control system, its pressure parts is forward and backward by 4, the header cylinder of upper and lower setting and connection one half bend of header cylinder up and down, and the band fin water pipe of header cylinder is formed before and after being communicated with.
Described burner is an atmospheric burner, is made up of Gas Pipe, nozzle, special-shaped combustion tube, little firearm, burnt gas valve etc.Stretch into burner hearth bottom with the vertically disposed special-shaped combustion tube of Gas Pipe, Gas Pipe and combustion tube are provided with nozzle accordingly, and special-shaped combustion tube is upwards offered many apertures, and the little firearm that is connected with Gas Pipe stretches in the burner hearth.
Described water inlet is communicated with preceding lower collecting box tube, preceding lower collecting box tube is communicated with back lower collecting box tube by band fin water pipe, back lower collecting box tube is communicated with back upper header tube by one half bend, and back upper header tube is communicated with preceding upper header tube by band fin water pipe, and delivery port is communicated with preceding upper header tube.
Described furnace wall adopts high-strength, lightweight flame-proof thermal insulation material, and furnace wall also is provided with the external packing that one deck contains insulation material outward.
Described exhaust opening top is provided with hurricane globe.
The described band fin water pipe that is communicated with the front and back header cylinder has many, and is communicated with upper and lower header cylinder respectively.
Described and the vertically disposed special-shaped combustion tube of Gas Pipe has many, is distributed on burner hearth bottom.
Described automatic control system, it is connected with burner, and safety protection function is achieved in that after opening boiler, control system is given little fiery valve signal, and little firearm is lighted a fire automatically.Light as little fire, then system opens, and the big fire valve system begins normal operation.Flame-out under certain conditions as little fire, then watch-dog cut out big fire automatically in 0.2 second, little fiery valve system self-locking.In addition, also can realize temperature auto control synchronously with burner.Boiler start-stop temperature is set in the system, when temperature is lower than when opening temperature, boiler startup, when temperature reaches when stopping temperature, the boiler gas lockout valve, boiler is out of service.System also independently is provided with high limit temperature, and when reaching high limit design temperature as the boiler leaving water temperature above normal temperature, then system closes the large and small fire valve automatically, system's self-locking.Safety devices such as in addition, system also is provided with power-off protection, the protection of dying, low water level protection.
The utility model compared with prior art because pressure parts adopts full water pipe, heat absorption capacity is good, intensity is high, the life-span is long, and is with fin on the steel pipe, has increased heating surface greatly, has improved the thermal efficiency.Because burner adopts unique special-shaped combustion tube, has improved combustion intensity, has increased the unit are combustion power.Because burner is the air suspended type structure, can adapt to pressure oscillation, (be that gaseous-pressure is big, it is many to suck a wind, and gaseous-pressure is little, and it is few to suck a wind to regulate air distribution voluntarily.), sufficient combustion, combustion chemistry is not exclusively lost little, therefore, thermal efficiency height.Because burner is equipped with little firearm, during boiler startup, lights little fire earlier, when the normal smooth combustion of little fire, automatic control system is just opened gas valve, and fuel just can enter the boiler normal combustion, can not produce deflagration phenomenon, and is therefore, safe and reliable to operation.Owing to burner structure is simple, only need to change just different sources of the gas such as energy gas-firing, liquefied petroleum gas, coal gas, fire damp gas of few parts, fuel tolerance is strong.Owing to taked the automation combustion system, comprise flame monitoring, blowout protection, safety devices such as explosion-proof, therefore, guaranteed safe operation.Because furnace wall adopts not only fire-resistant but also material insulation is trembled, refractory temperature is up to 1300 degree, and heat-insulating property surpasses flexible mineral wool insulation material, greatly reduces boiler weight.Furnace wall also is provided with one deck insulation material outward, because of double-layer heat insulation is arranged, has reduced radiation loss, has mentioned the thermal efficiency.Because the boiler top is provided with hurricane globe, its unique design can prevent big wind-fall row, avoids blowing out little fire and causes blowing out; Can prevent that the too high draft of chimney is excessive, reduce the thermal efficiency, energy balance furnace pressure; Can prevent to cause the accident after flue from stopping up.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
