The type of flue gas heat recovery of waste heat recovery Wei Electrical Industry

WYRG-XF ultra heat pipe waste heat recovery boiler WYRG-XF type superconducting heat pipe heat recovery boilers are coal, oil, gas boilers waste heat recovery equipment, smoke vents installed in the boiler or flue, the flue gas heat recovery after heated air, hot air can be used as boiler combustion and dry materials. Its structure is shown below; four weeks headers, middle partition separating the upper and lower side of the channel, full-finned tube heat pipe, heat pipe can replace a single. Work, the lower temperature flue gas flowing through the collector heat pipe erosion, when heat pipe heat, heat the flue gas temperature drops. Heat pipe heat transmitted to the upper part of the absorption of the cold air flowing through the upper part of the heat pipe is heated. At this time the exothermic heat pipe, heat the air temperature rises. Waste heat recovery boiler is to recycle waste heat is to improve energy efficiency, reduce production costs, protect the environment of the most direct and economical means one. Boiler flue gas temperature directly affects the security of the boiler unit of the economy and the tail heating surface work. Select a lower exhaust gas temperature can be reduced boiler flue gas loss, help improve boiler thermal efficiency, saving energy and boiler operating costs. But filling the lower exhaust gas temperature to reduce the tail heating surface of flue gas and the working medium heat temperature and pressure, heat transfer area increases, early metal consumption and equipment investment increased. In addition exhaust gas temperature is too low can also cause backpass sulfuric acid vapor condenses, the low temperature heating surface corrosion plugging ash, so the majority of the boiler flue gas temperature at about 200 ℃. Waste heat recovery boiler main equipment is a heat pipe, which is a heat transfer element having a novel ultra-high thermal conductivity. Heat pipe originated in the 1960's the United States, in 1967 a stainless steel - water heat pipe was first satellite into Earth orbit and run successfully, thermal management theory was put forth to get the attention of scientists from various countries, and launched a large number of research work, so that the heat pipe technology to quickly develop. Heat pipe technology originally developed for the aerospace field, in China since the 1970s began to heat pipe research, since the 1980s have developed a heat pipe gas - gas heat exchanger, heat pipe air - water heat exchanger, heat pipe waste heat boiler, Heat pipe steam generators, heat pipe heat pipe hot stove, and other products, so that the heat pipe in the building materials industry, metallurgy industry, chemical and petrochemical, power engineering, textile industry, glass industry, electrical and electronic engineering and other fields are widely used.
