Abstract
The utility model relates to a gas saving device for the natural gas boiler, in particular to a device to recycle the boiler exhaust heat, i.e. a device to promote the thermal efficiency of the civil hot water gas boiler and the industrial steam gas boiler, which is composed of an internal drum, an external drum, a diameter reducing drum, an exhaust fume outlet, a water intake pipe, a sprinkling device and so on. The utility model carries out heat exchange through direct contact of the system backwater or the cold water with the boiler exhaust fume, the exhaust fume heat is recycled by heating the water flowing into the boiler or the water tank, thus not only increasing the thermal efficiency by 5%-15%, but also further purifying the fume exhausted into the atmosphere. Due to the technical characteristics, the utility model can be used in the renovation of civil and industrial boilers or newly designed boilers.
Description
Technical field
The utility model relates to a kind of supporting energy-conservation province device of air of natural gas boiler that is, promptly is applicable to civil natural gas hot-water boiler and industrial natural gas steam boiler.
Background technology
At present, generally more than 180 degree, the heat loss of smoke evacuation is bigger for the exhaust gas temperature of the gas fired-boiler of domestic production, if do not take measures, and burning 1m
3The heat that the steam of natural gas is taken away is up to more than 10%, and this is very objective heat loss.The combustion gas now particularly price of natural gas is also somewhat expensive, for the gas fired-boiler user, looks forward to the specific energy consumption that reduces combustion gas invariably, looks forward to the saving operating cost.Therefore the exhaust gas temperature of putting forth effort to reduce gas fired-boiler is the realistic approach that improves the natural gas boiler thermal efficiency.
Summary of the invention
Natural gas characteristic and data that the utility model basis provides about scientific and technological data, 10% the water that promptly whenever condenses, boiler thermal output can improve about 1.2%.Because have sulphur content hardly in the natural gas, the cold end corrosion problem can not considered.Therefore, exhaust gas temperature can be reduced to below 100 degree fully.Because the thermal efficiency of conventional boiler has reached more than 90%, if can reduce exhaust gas temperature, the latent heat of vaporization of condensate water reclaimed be used, the thermal efficiency of boiler will further improve, and its value just can be above 100%, in addition; Because in the condensation flue gas steam time, can remove the harmful substance in the flue gas easily, therefore, the utility model adopts the system hypothermia backwater or cold water is direct and the hot flue gas of the original discharging of boiler carries out the direct contact heat exchange, not only make the thermal efficiency of conventional boiler can improve about 10%, and making the flue gas that is discharged into atmosphere clean more, ring can twoly be protected the benefit highly significant.
