我国有工业锅炉约20万台,每年耗煤约二亿吨,占我国年煤炭产量的三分之一。工业锅炉数量多,分布广,能耗大,是我国节能工作中重点对象之一。鼓、引风机和锅炉给水泵是工业锅炉的主要辅机,也是工业锅炉主要耗电设备,一般约占锅炉设备总耗电量的80—90%。据对装置三台 KZL 4—13型锅炉的锅炉房统计,这三种主要辅机的电耗占锅炉设备总耗电量的85.2%,其中鼓、引风机占56.3%,给水泵占28.9%。因此,研究鼓、引风机和给水泵
China has about 200,000 industrial boilers, consuming about 200 million tons of coal each year, accounting for one-third of China’s annual coal output. The number of industrial boilers, widely distributed, high energy consumption, is one of the key targets of our energy-saving work. Drums, induced draft fans and boiler feed pumps are the main auxiliary equipment for industrial boilers and are also the main power consuming equipment for industrial boilers, accounting for approximately 80-90% of the total power consumption of boiler equipment. According to the statistics of the boiler room of three KZL 4-13 boilers, the power consumption of these three main auxiliary machines accounted for 85.2% of the total power consumption of the boiler equipment, of which drums and induced draft fans accounted for 56.3% and feed pumps accounted for 28.9% . Therefore, research drums, induced draft fans and feed pumps
