我厂于1991年5月使用四川五通桥盐厂清灰剂分厂生产的EMEI化学清灰剂。一年生产实践表明,该清灰剂具有对热力设备无腐蚀,操作简单,方便、完全等特点,使用效果显著。使用清灰剂后,锅炉排烟温度降低了8℃,锅炉传热效率增加了5％,每年可节省重油500吨以上;我厂现配用的WGZ—35/39—11锅炉每月消耗清灰剂120多公斤,年消耗仅2.5吨,按购进价4000元/吨计,年投资1万元。如果重油价按580元/吨计
I plant in May 1991 to use Sichuan Wutong Bridge salt plant cleaning agent plant EMEI chemical cleaning agent. A year of production practice shows that the cleaning agent has no corrosion on the thermal equipment, simple operation, convenience, completeness and other characteristics, the use of significant results. The use of cleaning agent, the boiler exhaust gas temperature decreased by 8 ℃, the boiler heat transfer efficiency increased by 5%, saving more than 500 tons of heavy oil per year; I plant is equipped with WGZ-35 / 39-11 boiler consumed monthly More than 120 kilograms of ash, the annual consumption of only 2.5 tons, according to the purchase price of 4,000 yuan / ton, the annual investment of 10,000 yuan. If the heavy oil price by 580 yuan / ton meter
