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:
A kind of condensing boiler, comprise burner, condensing heat exchanger, combustion chamber, remaining cigarette flue, grid vapourizing unit and blower fan, in described condensing heat exchanger housing, combustion chamber is set, described grid vapourizing unit one end is communicated with burner, the other end and combustion chamber, described grid vapourizing unit is by shell and grid is affixed forms, the wind outlet of described blower fan connects burner, the top barrel of described combustion chamber is provided with multiple equally distributed smoke tube, the port of the smoke outlet of described smoke tube down, described condensing heat exchanger top is provided with exhaust opening, condensation dehydration device is provided with between described exhaust opening and combustion chamber, air preheater is provided with between described two groups of condensation dehydration devices, waterworks are provided with between described combustion chamber and condensation dehydration device, the described waterworks mouth of pipe connects to water shunting atomizer, the barrel of described condensing heat exchanger water space capacity arranges hot water outlet, the bottom of described condensing heat exchanger arranges blow-off pipe, the condensing heat exchanger housing at described air preheater two ends is provided with inlet of cold air and hot air outlet, hot-air duct is provided with between described hot air outlet and burner.
As the further scheme of the present invention: described grid is formed by intersecting affixed stainless steel materials
As the present invention's further scheme: described condensation dehydration device is provided with more than two.
As the present invention's further scheme: described condensing heat exchanger arranges water-level gauge.
Beneficial effect of the present invention is: under the effect of blower fan, the fuel lighted is blown in grid vapourizing unit, because grid is heated, grid after heating is continuous conversely again vaporizes the fuel lighted entered in it further and burns, make full combustion of fuel, by arranging smoke tube and condensation dehydration device, effectively high-temperature flue gas and boiler feedwater can be carried out direct contact heat transfer, effectively can improve the thermal efficiency, reduce the temperature of smoke evacuation; Because flue gas fully contacts with feedwater, extremely low to the carbon monoxide of airborne release, hydrocarbon, sulfide and oxynitrides, minimizing environmental pollution; Air preheater is set, makes the cold air of burning by the abundant preheating of condensing heat-exchange, again improve heat exchange utilization rate.
