Description
(1) technical field
The utility model relates to a kind of boiler.Be specifically related to a kind of external independent energy-saving appliance and the horizontal fuel oil of condenser (gas) condensing steam boiler be with.Belong to the heating equipment technical field.
(2) background technology
For sustainable development and the requirement on environmental protection that adapts to national economy, coal type fuel is progressively changed into oil, gas type fuel.Oil, gas type fuel are easy to carry and use, and are guaranteeing not produce environmental pollution basically under the good burning condition, the calorific capacity height, and this makes fuel oil, gas fired-boiler realize operation automation, high efficiency.In recent years because oil-burning gas-fired boiler is small, automaticity is high, easy for installation, and under various heating agents, can obtain very convenient and use flexibly, oil-burning gas-fired boiler has obtained developing widely and using.
In the tradition oil-burning gas-fired boiler, owing to reasons such as flue gas resistance, cold end corrosions, the exhaust gas temperature design all is higher than 150 ℃, the boiler of magnetic tape trailer portion heating surface even be higher than 250 ℃ not, water vapour is in the superheated steam state in the flue gas, can not condense into aqueous water and emits the latent heat of vaporization, therefore, China is the same with other countries, and the low heat value that adopts fuel during boiler heating power calculates is as calculating benchmark.If can drop to exhaust gas temperature enough lowly, the water vapour that is superheat state in the flue gas will condense into aqueous water and emit the latent heat of vaporization.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and exhaust gas temperature is dropped to enough low, make the water recovery that is superheat state in the flue gas become aqueous water and emit external independent energy-saving appliance of being with of the latent heat of vaporization and the horizontal fuel-firing gas-firing condensing of condenser steam boiler.
The technical solution of the utility model is as follows: a kind of external independent energy-saving appliance and the horizontal fuel-firing gas-firing condensing of condenser steam boiler be with, comprise burner, front smoke box, flue, shell, explosion proof door, strile-back chamber and convection bank, flue, strile-back chamber and convection bank all is arranged in the shell, flue is horizontally placed on bottom in the shell, the chamber of strile-bacing is arranged at the flue rear side, with the flue intracavity inter-connection, front smoke box is arranged at the preceding shell wall of the shell outside, convection bank is horizontally placed on the shell internal upper part, the tube side of convection bank is connected with the front smoke box and the chamber of strile-bacing, burner is arranged at the flue front side, explosion proof door is arranged at behind the shell on the shell wall, and be connected with the rear portion, chamber of strile-bacing, top at shell independently is furnished with energy-saving appliance and condenser, and the condenser shell side is connected with the energy-saving appliance shell side, and the energy-saving appliance shell side is connected with the tube side of convection bank, the condenser tube side is connected with the energy-saving appliance tube side, and the energy-saving appliance tube side is connected with shell.
The flue gas that burner combustion produces is successively through flue, the chamber of strile-bacing, convection tube tube side and energy-saving appliance shell side in the shell, flue-gas temperature drops to about 160 ℃ and enters condenser, and temperature enters atmosphere after further being reduced to below the steam dew-point temperature in the flue gas (60 ℃～70 ℃); Feedwater adds through condenser, energy-saving appliance that heat absorption is laggard goes into shell, and further heating produces steam in shell, and the shell internal heating surface is flue and two backhauls of convection tube.
The heat exchanger tube of described energy-saving appliance and condenser all adopts the spiral fin coil of band extended surface.
Described front smoke box adopts double sealing structure.
The beneficial effects of the utility model are:
1, owing to after being fuel combustion with oil or gas, vapour content height in the flue gas, condenser boiler is by effectively reducing the exhaust gas temperature of fuel oil (gas) boiler, make the water vapor condensation in the flue gas emit the latent heat of vaporization, emit the latent heat of vaporization by reclaiming obvious heat of smoke and the water vapour condensation that the temperature reduction is emitted in the flue gas, by reasonable heating surface and flow scheme design, boiler thermal output can reach more than 100%, can make boiler improve about 10% on the basis of original thermal efficiency.And control boiler resistance keeps constantly substantially, and boiler is thermal efficiency height not only, and adaptive surface is wider.The back pressure that burner had of original boiler just can satisfy.
2, adopt independent energy-saving appliance, the condenser of Influences of Structure of Spiral Finned Tube, volume is little, good looking appearance.
3, external energy-saving appliance, condenser is arranged in the boiler top, and no floor space is changed easy for installationly, adopts ND steel (09CrCuSb) to prevent from acid corrosion to have improved service life greatly.
4, the rational Application of corrugated flue and enhanced heat transfer component energy-saving appliance, condenser spiral fin coil is not only strengthened the turbulent flow heat transfer of high-temperature flue gas but also is effectively absorbed expanding with heat and contract with cold of body of heater.
5, front smoke box adopts unique double sealing structure, solved the difficult problem that cigarette is leaked at horizontal malleation internally fired boiler long-time running ubiquity smoke box place, prevent the heat loss that smoke spillage causes, adopted the cleaning of being convenient to smoke box and smoke pipe and the double swing doors of maintenance simultaneously; Be furnished with the spring explosion-protection equipment, just in case furnace puff can open rapidly when inner flue gas of the stove pressure increases suddenly, thereby huge flue gas pressures in the discharging stove is guaranteed safe operation of the boiler.On the explosion proof door flame-observing hole is housed so that check the flame combustion situation, thereby helps stoker's personnel adjustment burner, guarantee efficiency of combustion to optimum state.
6, the horizontal wet back of the body two return structure of boiler entire arrangement employing, center, combustion chamber low level is arranged, the design philosophy that heat exchange smoke pipe left-right symmetry distributes, the heat exchange load is uniform and stable, help the circulation of working medium side carbonated drink, reduce the generation of lack of water accident to greatest extent, improve boiler safety.Adopt the design philosophy of the maximum heating surface of the big shell of big flue simultaneously, burning is difficult for carbon distribution fully, and fuel savings reduces the flue thermic load, reduces NO
XGeneration, have efficient high output foot, the distinguishing feature that overload capacity is strong simultaneously.Adopt the big shell design that can guarantee enough vapor spaces and hydrospace, the boiler water capacity is big, and load is steadily added water separator in the rational pot, guarantees steam quality, is suitable for long-time running.
