Description
Technical field
This utility model is related to a kind of New forced circulation fuel-firing gas-firing pipe hot water boiler.Belong to boiler technology field.
Background technology
At present, 2.3 times for world average level of China's energy consumption per unit of output value, main energy-consuming product specific energy consumption is than external
Advanced level is high by 40%；China often create the energy consumption of one dollar of GNP be Germany 4.97 times, Japan 4.43 times, the 2.1 of the U.S.
Times, 1.65 times of India, this is to cause one of entreprise cost rising, the major reason of deficiency in economic performance.According to investigations, China's industry
The product energy, the consumption of raw material account for 75% of enterprise's production capacity or so, if reducing one percentage point can just obtain more than 100 hundred million
The benefit of unit.
Recent two decades come, on the one hand, oil, the development rate of natural gas are greatly improved, and country eliminates large- and-medium size cities
Use the restriction of oil product and natural gas；On the other hand with the enhancing of global environmental consciousness, Chinese national economy is developed rapidly, people
People's living standard is improved constantly, and China is adjusted to fuel policy, is environmental pollution and the air for improving large- and-medium size cities
Quality, government start to encourage public enterprises and institutions to use oil product or natural gas, greatly accelerate the development of oil-burning gas-fired boiler.
In the development of self-contained fuel-firing gas-firing hot water industrial boiler, as fuel-firing gas-firing stove is different from medium boiler, there is no heat
Hysteresis effect, after blowing out, boiler does not vaporize danger, so not having many restrictions, boiler to hot-water boiler heating surface arrangement
Species is also varied.The type of furnace that China mainly introduces, produce has the double drum longitudinal water pipe pots of WNS horizontal tubular boilers, SZS
The structures such as stove, corner tube boiler.This three classes type of furnace respectively has pluses and minuses, and wherein WNS horizontal tubular boilers water capacity is larger, and energy consumption is relative
It is slightly higher；The double drum longitudinal water-tube boilers of SZS, volume are larger, and number of tubes is more, and joint is more, and welding job amount is big；Cornue boiler
Stove, header, steelframe, connecting pipe are more, and heavier-weight, flow process are more, and water resistance is big, complex structure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of New forced circulation combustion for above-mentioned prior art
Oily combustion gas pipe hot water boiler, compact conformation, water capacity are little, and flow process number is few, lightweight, supporting integrated energy-saving device so that row
Cigarette temperature is low, and efficiency high, heat loss are few.
The technical scheme in the invention for solving the above technical problem is：A kind of New forced circulates fuel-firing gas-firing water pipe
Hot-water boiler, it is characterised in that it includes burner, burner hearth, body front header and body rear set box, the burner hearth is located at body
Between front header and body rear set box, body front header and body rear set box are fixedly installed on base, and the burner is installed
It is connected in the middle part of body front header and with burner hearth, the burner hearth includes the circular horizontal membrane wall for setting gradually from inside to outside
Burner hearth, annular advection pipe and circular horizontal membrane wall pipe, the circular horizontal membrane wall burner hearth and annular level pair
Formed between flow tube it is first annular walk cigarette channel, is formed between the annular advection pipe and circular horizontal membrane wall pipe
Second ring walks cigarette channel, it is described it is first annular walk cigarette channel and the second annular walk the top of cigarette channel and be connected with the combustor of burner hearth
It is logical, it is described it is first annular walk cigarette channel and the second annular walk the bottom of cigarette channel and be connected with the connection flue below burner hearth, institute
State connection flue to collect mouth by finned tube energy-saving appliance and smoke evacuation and be connected, be provided with into water in the bottom of the body rear set box
Mouthful, outlet is provided with the top of body front header.
Preferably, the body front header and body rear set box are separated into the part of upper, middle and lower three, between each part
Turned on by burner hearth, by system moisture into several flow processs.
Preferably, outsourcing heat-insulation layer is coated with the outside of the burner hearth.
Compared with prior art, the utility model has the advantage of：
1st, the boiler body is realized all Water flow-path unified plannings, is reduced unmanaged face using double header designs in front and back
Pressure parts（Header, drum, pipeline）Quantity, reduce flow process and water resistance, drop lower steel consumption.
2nd, this boiler convection area is the annular advection pipe and circular horizontal membrane wall by being centered around around burner hearth
Pipe is constituted, and heat exchanging water pipe is all horizontally disposed, and in the shape of falling ω, this structure for closely surrounding significantly reduces pot to exhaust gases passes
Furnace body size.In addition, placed the integrated energy-saving device isometric with boiler in body side so that boiler overall dimensions are more
It is compact, allow also for the detachability of energy-saving appliance.
3rd, this boiler pressure part has circular horizontal membrane wall burner hearth, annular advection pipe, circular horizontal membrane wall
Pipe, body front header and body rear set box, in addition to first three is belonging to heating surface, behind two headers belong to unmanaged portion
Part, water capacity are also fewer, therefore the hot-water boiler heats up comparatively fast, and blowing out heat loss is few, is particularly suitable for the heating of the normal start and stop of Jing
User, overall efficiency are high.
4th, this boiler adopts finned tube energy-saving appliance as convection heating surface, by low-temperature return water come cooled flue gas so that row
Cigarette temperature is reduced to less than 100 DEG C, only than high 25-30 DEG C or so of return water temperature, hot-water boiler efficiency greatly improved.Due to heat
Homogeneous solution-type reactor is generally used for winter heating, and winter environment temperature is relatively low, so actual flue-gas temperature will be lower.
5th, body header is in annular, is arranged in front and back, heating surface tube vertical equity arrangement so that heating surface tube quantum count is big
It is big to reduce, while supporting header or drum quantity are also significantly reduced, each one before and after only needing, so having simplified header use
Amount, reduces steel consumption.Compared with the corner tube boiler of same specification, header usage amount reduces 70%.Further, since header reduction, pipe
Quantum count is reduced, so reducing Water flow-path, same flow process number is reduced, and affects larger local resistance to diminish water resistance, therefore
Water resistance is reduced, and can equally reduce the power consumption of system circulation water pump.
