Abstract
The invention provides a combustion system of a heat storage type heating furnace. The combustion system comprises the heating furnace, heat storage boxes are arranged on the outer wall of the heating furnace, air faucets are arranged in the heating furnace, the air faucets are connected with the heat storage boxes through pipelines, flat flame fans are arranged right opposite to the air faucets and perpendicular to the air faucets, the air faucets and the flat flame fans are arranged in conical holes in the outer wall of the heating furnace, the number of the heat storage boxes is two, the two air faucets are arranged correspondingly, the working states of the two air faucets are different, namely, when one air faucet is in an air suction state, the other air faucet is in an air injection state, and the working states of the air faucets can be converted. The combustion system of the heat storage type heating furnace has the advantages that energy is saved, consumption is lowered, waste gas collection is facilitated, environment pollution is reduced, heat storage energy is more sufficient due to the fact that the two heat storage boxes are used for conducting heat storage processing for storing heat respectively, the working efficiency of the heat storage type heating furnace is improved and the heat storage type heating furnace is convenient to clean.
Description
Technical field
The present invention relates to a kind of combustion system of heating furnace, relate in particular to a kind of combustion system for recuperative heater.
Background technology
Industrial heating furnace, typically uses conventional gas and oil combustion heating.Because heating furnace does not have treating apparatus, cause burning insufficient, reduce production efficiency, and the flue gas after easily collecting burning not, cause environmental pollution.Also have now recuperative heater, recuperative heater is a kind of novel heating furnace for steel rolling mill, has efficient burning, recycles the advantages such as flue gas and low carbon dioxide emission.Extensive use in industrial enterprise, plays important facilitation to energy-saving and emission-reduction work.But current recuperative heater only has a heat storage tank, in gas conversion, easily cause gas to mix, waste gas cannot be discharged, and is not easy to clean.Therefore, solve that the easy gas of recuperative heater mixes and not the problem of easy cleaning just seem particularly important.At present, the flame-thrower nozzle of heating furnace, is to adopt flame on the direct workpiece toward needing to heat of nozzle mostly, is heated inhomogeneous while tending to like this cause workpiece heating; Use oil-gas heating, flame temperature is higher, and flame directly sprays on workpiece, usually can cause the damage of workpiece, or does not reach the effect after workpiece heating.On the other hand, use nozzle directly toward flame on workpiece, the oil-gas ratio of its consumption is more, has increased the production cost of enterprise.
Summary of the invention
In order to address the above problem, the invention provides the combustion system of recuperative heater, comprise heating furnace, heating furnace outer wall is provided with heat storage tank, in heating furnace, be provided with valve, valve is connected with heat storage tank by pipeline, valve right opposite is provided with the flat flame fan perpendicular to valve, valve and flat flame fan are arranged in the bellmouth on heating furnace outer wall, and heat storage tank has two, and correspondence is provided with two valves, the duty of two valves is contrary, when a valve is operated in suction condition, another is operated in jet state, and the duty of valve can convert.
Further improve and be: flat flame fan is in the form of annular discs, flat flame fan is provided with the circle being surrounded by aperture, and flat flame fan periphery is provided with breach.
Further improve and be: described bellmouth is larger over against one end boring ratio of inside heating furnace.
Beneficial effect of the present invention is: by heat storage tank is set, the waste gas with temperature stored, heat put aside, and energy-saving and cost-reducing, and be conducive to the collection of waste gas, reduce environmental pollution, by two heat storage tanks, carry out regeneration treatment, accumulation of heat respectively, make heat-retaining capacity more sufficient, improve the operating efficiency of recuperative heater, be convenient to clean, heating member is subject to thermal velocity fast, flame can directly not beaten on workpiece, and heating member is heated evenly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the bellmouth structural representation at valve of the present invention and flat flame fan place.
Wherein: 1-heating furnace, 2-heat storage tank, 3-valve, 4-pipeline, 5-flat flame fan, 6-bellmouth.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the combustion system of recuperative heater, comprise heating furnace 1, heating furnace 1 outer wall is provided with heat storage tank 2, is provided with valve 3 in heating furnace 1, valve 3 is connected with heat storage tank 2 by pipeline 4, by heat storage tank 2, the waste gas with temperature is stored, heat is put aside, energy-saving and cost-reducing, and be conducive to the collection of waste gas, reduce environmental pollution.Valve 3 right opposites are provided with the flat flame fan 5 perpendicular to valve 3, valve 3 is fanned in 5 bellmouths 6 that are arranged on heating furnace 1 outer wall with flat flame, heat storage tank 2 has two, correspondence is provided with two valves 3, the duty of two valves 3 is contrary, when a valve 3 is operated in suction condition, another is operated in jet state, the duty of valve 3 can convert, by two heat storage tanks 2, carry out regeneration treatment, accumulation of heat respectively, make heat-retaining capacity more sufficient, improve the operating efficiency of recuperative heater, be convenient to clean, while being burned to a certain degree in heating furnace 1, two valves 3 are air-breathing and jet respectively, produce relative wind, burning gases are circulated in heating furnace 1, the efficiency of heating furnace 1 is got a promotion.It is 5 in the form of annular discs that flat flame is fanned, and flat flame fan 5 is provided with the circle being surrounded by aperture, and flat flame is fanned 5 peripheries and is provided with breach, and flame can directly not beaten on workpiece like this, heating member is heated evenly, fuel saving.Bellmouth 6 is larger over against one end boring ratio of heating furnace 1 inside.
The beneficial effect of the present embodiment is: energy-saving and cost-reducing, and be conducive to the collection of waste gas, reduce environmental pollution, by two heat storage tanks, carry out regeneration treatment, accumulation of heat respectively, make heat-retaining capacity more sufficient, improve the operating efficiency of recuperative heater, be convenient to clean, heating member is subject to thermal velocity fast, flame can directly not beaten on workpiece, and heating member is heated evenly.
