Superconduction environmental protection and energy saving fast heating type gas heater
Technical field
The novel water heater technical field that relates to of this practicality exactly is a kind of environmental protection and energy saving fast gas heater technology of carrying out heat exchange and waste heat recovery with superconduction temperature device.
Background technology
Along with developing rapidly of combustion gas cause and improving constantly of living standards of the people, China's gas heater demand increases sharply in recent years, and all render to market with 400~5,000,000 quantity every year.But gas heater is wasted in the use of combustion gas greatly at present, shows that mainly the thermal efficiency of water heater is low.Conventional gas instantaneous water heater is by GB GB6932-2001 regulation, and its exhaust gas temperature θ Py is more than or equal to 110 ℃, and the thermal efficiency is more than or equal to 80%.Just the production status of China is seen, generally all about 220 ℃, heat dissipation of exhaust fume is big, adds the thermal losses on the burner wall for the water heater exhaust gas temperature, and the thermal efficiency of general water heater has only about 75%.Obviously, the waste heat of gas heater and the thermal losses on the burner wall all fail to make full use of, and cause the very big waste of the energy.Although gas heater is used the thermal efficiency that the boundary makes great efforts to improve water heater always, owing to be subjected to the restriction of various factors, even Chinese state-of-the-art factory, the thermal efficiency of its gas heater generally also has only about 84%.The thermal efficiency of external like product generally also has only 85%.Because the combustion gas price is higher relatively in China, exploitation high efficiency burnt gas apparatus meaning is more great.In addition, gas heater smoke exhaust heat loss is serious, except that causing energy significant wastage, has also seriously influenced human natural living environment, even poisonous gas poisoning phenomenon when bathing takes place.As everyone knows, the pollution threat of large natural environment people's existence and development of human society, according to interrelated data, annual in the world at present have 700,000,000 tons pollutant to surround the earth, in a large amount of harmful substances that human lives's atmosphere is floating, the photochemical smog of more than 50 hundred million tons of nitrogen oxide that fuel produced of the annual burning-off of light just has 200,000,000 tons, and As time goes on this pernicious gas can get more and more.This serious harm that pollution caused has caused that countries in the world government pays much attention to, and formulates the way of contaminated solution protection environment one after another.The exhaust gas temperature of current widely used straight-line and chimney flue type gas instantaneous water heater (and common water heater) is higher, because only used the part of its heat flow during gas water heater working, sensible heat can't be used to its latent heat part.Therefore, develop the high efficiency burnt gas apparatus, and the natural environment of protecting the mankind to depend on for existence is had crucial meaning.
