The specific embodiment
Fire coal has produced a large amount of flue gases by burning in boiler, and the heat energy in boiler smoke is comprised of sensible heat and latent heat two parts, conventionally in burner hearth, has only utilized the sensible heat of partial fume.Traditional exhaust gas temperature is generally higher than 250/350 ℃, and the water vapour in flue gas, still in superheat state, can not discharge the latent heat of vaporization.If the exhaust gas temperature of boiler drops to enough levels, the water vapour that is superheat state in flue gas will condense into water and emit the latent heat of vaporization, and this part of heat for boiler, can increase substantially the thermal efficiency, Here it is condenser boiler.As everyone knows, boiler thermal output is to calculate gained with fuel low heat value, do not consider the heat loss of latent heat of vaporization amount in the high-order calorific capacity of fuel, so the conventional boiler thermal efficiency generally can only reach 60% left and right.And condenser boiler has utilized the latent heat of vaporization of the steam in flue gas, the thermal efficiency just can increase substantially.Obviously, condenser boiler has a great difference with conventional boiler in design philosophy.Owing to condensing into the latent heat of vaporization of water, obtain and recycle, the sensible heat that has again a flue gas cool-down also recycle, boiler thermal output will improve greatly, Fuel Consumption greatly reduces, and has saved the energy.At present, external produced condenser boiler is all to utilize natural gas for fuel, and take the condenser boiler that coal is fuel, there is no manufacturer production both at home and abroad.
Condenser boiler not only has efficient energy-efficient performance, and has superior environmental-protecting performance.The fume environment protection purification mechanism of condenser boiler is: flue gas condensing is complicated heat and mass transfer process, and flue gas condensing is steam in flue gas, from little water droplet, becomes large water droplet, from large water droplet, becomes the process of condensed water.In this course, chemical substances different in flue gas can incorporate in condensate liquid, or and condensate liquid generation chemical reaction.Be dissolved in condensed water, destroyed the formation of vapour bath colloidal state, purified the harmful substance in flue gas.Flue gas is the purification to So2 and So3 in condensation process, when cigarette temperature is higher, part So2 is converted to So3, when heat exchanger wall surface temperature is higher, steam reaction in part So3 and flue gas and generate H2So4 steam, when temperature reduces, So3 and steam are in conjunction with generating sulfuric acid vapor.In condensing heat exchanger, the reduction of flue-gas temperature, heat exchange wall surface temperature is during lower than dew-point temperature, and H2So4 steam forms acid water droplet on heat-transfer surface.Flue gas condensing can produce condensed water, the acid water droplet that pernicious gas condenses into will be dissolved in condensed water, and when in condensed water, pernicious gas reaches capacity state, in flue gas, harmful gas concentration reduction reaches maximum, it is maximum that clean-up effect now reaches, and reaches maximum theoretical effect.Therefore, the environmental-protecting performance of condensing environment-protection boiler is very obvious, is greatly better than the environmental-protecting performance of plain cylindrical furnace
