锅炉省煤器是锅炉的辅助设备,而非“蒸汽锅炉零件”。省煤器定义根据中华人民共和国国家标准GB/T2900.48-2008《电工名词术语锅炉》的定义,省煤器是利用给水吸收锅炉尾部低温烟气的热量,降低烟气温度的对流受热面。由于该装置在降低锅炉排放烟气温度的同时,可提高锅炉给水温度,节约了燃料的消耗量,故将其形象的称为省煤器。省煤器分类按使用材料可将省煤器分为铸铁式和钢管式。铸铁式省煤器,是将熔融金属浇入型模中冷却凝固成形制得。因为铸铁件强度
Boiler economizer is a boiler auxiliary equipment, rather than “steam boiler parts ”. Economizer Definition According to the definition of “National Electrotechnical Terminology Boiler” GB / T2900.48-2008 of the People’s Republic of China, an economizer is a convection heating surface that uses feed water to absorb the heat of low-temperature flue gas in the rear of a boiler to reduce the flue gas temperature. Since the device reduces the temperature of the flue gas discharged from the boiler, it can increase the temperature of the boiler feed water and save the fuel consumption. Therefore, the image is called economizer. Economizer classification According to the use of materials can be divided into cast iron and steel tube type. Cast iron economizer, is poured into the molten metal mold cooling and solidification obtained. Because of the strength of cast iron
