Rear boiler wall temperature of the metal device Degree if less than the condensation point of sulfuric acid vapor (acid dew point), will be in the form Surface to form liquid sulfuric acid (acid gel). Over the years, air preheater for Tail heating plant boiler wall temperature is too low due to acid dew rot caused by Erosion, frequent ash and block, and has been without an effective solution, because Instead. The past, a variety of boiler design is often at the expense of thermal efficiency of boiler Price. By increasing the exhaust gas temperature to ease (not eradication) acid gel Corrosion. And to simply increase the exhaust gas temperature will inevitably cause a large number of low- Temperature heat waste. Nevertheless, the air preheater are often run from one to Corrosion is still there after two years, until the perforation, which is troubled by the boiler industry A global problem. Composite phase change heat transfer device technology and device is a widely applicable For a variety of coal, oil, gas boilers, industrial kilns and smelting Kim, petrochemical and other energy-efficient heat transfer equipment, a new patent products Products. It comes from the Shanghai Jiaotong University, Professor Yang Benluo the original design Total Concept and nine invention patents, is the thermodynamics, heat transfer And boiler principle, automatic control and modern computing technology, a comprehensive Innovative and efficient integration, it has solved the boiler exhaust gas temperature is difficult To reduce the global problem, is the utilization of a
