Abstract
The invention discloses a condensing boiler. The condensing boiler comprises a burner, a condensing heat exchanger, a combustion chamber, a residual smoke duct, a grid gasification device and a fan, wherein one end of the grid gasification device is communicated with the burner, the other end of the grid gasification device is communicated with the combustion chamber, a plurality of uniformly distributed smoke guide pipes are arranged at the cylindrical wall of the top of the combustion chamber, the ports of the smoke outlet ends of the smoke guide pipes face downwards, a smoke exhaust port is formed in the top of the condensing heat exchanger, condensing dewatering devices are arranged between the smoke exhaust port and the combustion chamber, and an air preheater is arranged between the two groups of condensing dewatering device. The arranged grid gasification device can enable fuel to be fully combusted; by arranging the smoke guide pipes and the condensing dewatering devices, high-temperature smoke and boiler feed water can be effectively enabled to be direct contact for heat exchange, the thermal efficiency can be effectively improved, the temperature of exhausted smoke is reduced and environmental pollution is reduced; by arranging the air preheater, cold air for combustion is fully preheated through condensing heat exchange and the heat utilization rate is further improved.
Description
Technical field
The present invention relates to a kind of heat-exchanger rig, specifically a kind of condensing boiler.
Background technology
Condensing boiler is exactly sensible heat in utilize efficient waste heat of condensation retracting device high-temperature flue gas that absorption boiler discharges and the latent heat that discharges of water recovery, to reach the object improving boiler thermal output.Condensation heat homogeneous solution-type reactor is in order to reduce exhaust gas temperature, improve boiler thermal output, the measure taked allows flue gas stay boiler flue as much as possible flue gas is fully contacted with water, be exactly allow the content of discharging steam in flue gas reduce in addition as far as possible, but realize the device of these measures in prior art, there is complex structure in it, the problem of poor effect, the exhaust gas temperature of condensation heat homogeneous solution-type reactor in reality still can not obviously be reduced, and the exhaust opening of condensation heat homogeneous solution-type reactor also has white cigarette of emerging to take away more heat transfer more, if by this part heat recovery and utilization, production cost can not only be reduced, improve boiler thermal output, can also protection of the environment.
Summary of the invention
The object of the present invention is to provide a kind of condensing boiler, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to Fig. 1 ~ 2, in the embodiment of the present invention, a kind of condensing boiler, comprise burner 1, condensing heat exchanger 2, combustion chamber 3, remaining cigarette flue 8, grid vapourizing unit 16 and blower fan 17, in described condensing heat exchanger 2 housing, combustion chamber 3 is set, described grid vapourizing unit 16 one end is communicated with burner 1, the other end is communicated with combustion chamber 3, described grid vapourizing unit 16 is by shell 161 and grid 162 is affixed forms, described grid 162 is made up of the affixed stainless steel materials of intersection, the wind outlet of described blower fan 17 connects burner 1, its wind directly blows to grid vapourizing unit 17, under the effect of blower fan 1, the fuel lighted is blown into grid vapourizing unit 17 and enters in combustion chamber 3, the top barrel of described combustion chamber 3 is provided with multiple equally distributed smoke tube 6, the port of the smoke outlet of described smoke tube 6 down, described condensing heat exchanger 2 top is provided with exhaust opening 11, condensation dehydration device 8 is provided with between described exhaust opening 11 and combustion chamber 3, described condensation dehydration device 8 is provided with more than two, air preheater 9 is provided with between described two groups of condensation dehydration devices 8, waterworks 13 are provided with between described combustion chamber 3 and condensation dehydration device 8, described waterworks 13 mouth of pipe connect to water shunting atomizer 7, the barrel of described condensing heat exchanger 2 water space capacity arranges hot water outlet 5, the bottom of described condensing heat exchanger 2 arranges blow-off pipe 15, described condensing heat exchanger 2 arranges water-level gauge 14, condensing heat exchanger 2 housing at described air preheater 9 two ends is provided with inlet of cold air 12 and hot air outlet 10, hot-air duct 4 is provided with between described hot air outlet 10 and burner 1, make the cold air of burning can fully preheating.
When the present invention uses, under the effect of blower fan 17, the fuel lighted is blown in grid vapourizing unit 16, and enter in boiler through grid 162, because grid 162 is heated, grid 162 after heating is continuous conversely again vaporizes the fuel lighted entered in it further and burns, make full combustion of fuel, described combustion chamber 3 major part in condensing heat exchanger 2 is immersed in water, flame in burner 1 and flue gas enter combustion chamber from lower end, combustion chamber 3 connecting pipe, fire smoke gases is in combustion chamber 3 inside turn, by combustion chamber 3 sidewall heat passed to the water in condensing heat exchanger 2, then flue gas enters condensing heat-exchange space from smoke tube 6, after shunting the water smoke heat exchange after being atomized with waterworks, flue gas is discharged by exhaust opening 11, air preheater is set, by the further condensing heat-exchange of heat smoke after burning, make the abundant preheating of the cold air of burning, delivered in burner 1 by hot-air duct 4.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection domain of the claims in the present invention opinion.
