Description
Technical field
The utility model relates to field of boilers, particularly a kind of fuel-oil or fuel-gas boiler of horizontal built-in condenser/energy-saving appliance.
Background technology
in prior art, condenser is all generally the auxiliary device of boiler, is connected with boiler as back-end surfaces.Because of oil-burning gas-fired boiler with oil or gas for fuel, after burning, in flue gas, vapour content is compared with the height taking coal as fuel, and adding condenser effectively can reduce exhaust gas temperature, make a large amount of water vapor condensation in flue gas release the latent heat of vaporization, to raising boiler efficiency, energy-saving and emission-reduction, all there is considerable meaning.The condenser of prior art is the independently auxiliary genus equipment of boiler, and condenser will be arranged on upper boiler by connecting flue, or (tail) portion after being arranged on boiler, increases floor space, increases transport, installation cost.External condenser and connection flue external surface area greatly, add radiation loss, increase power consumption.
Summary of the invention
The purpose of this utility model is the fuel-oil or fuel-gas boiler providing a kind of horizontal built-in condenser/energy-saving appliance, solves the problems referred to above that prior art exists.Its compact conformation, floor space are little, transport simple installation, and the thermal efficiency is high, less energy consumption, good environmental protection.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
The fuel-oil or fuel-gas boiler of horizontal built-in condenser/energy-saving appliance, combustor 1 and shell 3 axis horizontal are arranged, the front end of flue 5 is connected with combustor 1, rear end arranges return combustion chamber 7 or back tube sheet 10, one end of long smoke pipe 6 is connected with front tube sheet 11, the other end is connected with back tube sheet 10, is provided with the condenser 9 of spiral fin coil in rear smoke box 8.
Described return combustion chamber 7 is connected with one end of short smoke pipe 4, and front tube sheet 11 is connected with the other end of described short smoke pipe 4.
Described front tube sheet 11 is connected with front smoke box 2.
Described long smoke pipe 6 is light pipe or threaded flue.
Described short smoke pipe 4 is light pipe or threaded flue.
The flame that combustor 1 sprays is washed into forward flue 5 until return combustion chamber 7, enter short smoke pipe 4 and be washed into forward front smoke box 2, after half-turn, enter long smoke pipe 6 at front smoke box 2 and proceed parallel baffled, then smoke box 8 after boiler is proceeded to, in rear smoke box 8, the condenser 9 with spiral fin coil is washed away in stagger arrangement, and flue gas is in condenser 9 heat release and enter air after partial condensation.Condenser 9 or energy-saving appliance are built in smoke box 8 after boiler, and exhaust gas temperature can be made to reduce, and improve boiler thermal output, more environmental protection.Be convenient to effective process containing after the flue gas condensing Water Sproading of nitrogen oxide and sulfide, decrease airborne release and pollute.
The beneficial effects of the utility model are:
1, reduce the heat loss of boiler: containing a large amount of protium in natural gas, produce a large amount of water vapour through burning.1.55KG water vapour can be produced after every 1NM3 combustion of natural gas, there is the considerable latent heat of vaporization, be approximately 3700KJ, account for about 10% of the low heat valve of natural gas.When exhaust gas temperature is higher, water vapour condensation can not release heat, and with fume emission, heat is wasted.Meanwhile, high-temperature flue gas also takes away a large amount of sensible heat, forms larger flue gas loss together.In order to reduce gas fired-boiler heat loss, flue gas condensing heat exchanger is set in fuel-oil or fuel-gas boiler afterbody, exhaust gas temperature is dropped to enough low level, water vapour in superheat state in flue gas will condense, the latent heat discharged by the physical sensible heat in heat exchange absorption smoke evacuation and water recovery is used, and the boiler thermal output being benchmark by fuel Lower heat value can meet or exceed 100%.Built-in condenser (energy-saving appliance) is connected with boiler without the need to peripheral hardware flue, lower than the radiation loss of traditional condenser.
2, improve fuel availability: by built-in condenser (energy-saving appliance), while reduction exhaust gas temperature, promote the temperature of boiler recirculated water (feedwater), make boiler be in high-temperature water all the time and run, the saving rate of fuel can reach 8-15%.Be convenient to effective process containing after the flue gas condensing Water Sproading of nitrogen oxide and sulfide, decrease airborne release and pollute.
3, adopt the heat exchange structure of special shape, heating surface adopts spiral fin coil, and the coefficient of heat transfer is high.Material is ND steel, there is not the possibility of acid condensate water corrosion, the move counter-current that flows to of recirculated water and flue gas ensure that the efficient of fume gas condensation rate, self-purging effect is supported in being arranged vertically of built-in condenser, the condensed water self formed can be unimpeded flow to bottom, keep the cleaning of heating surface while this makes it touch heating surface.
4, the boiler structure of built-in condenser (energy-saving appliance) is compact, floor space and take up room little, without the need to separately installing condenser, realizing one transport, saving installation cost and installation period.Need not worry for boiler plant type selecting mistake, save time, laborsaving, save worry.If if boiler does not arrange condenser, the space of condenser also can arrange energy-saving appliance, has joint cost equally, energy consumption saving wheel, the corresponding effect in joint space.Practical.
