工业锅炉是我国目前应用面宽、数量多的耗用一次能源的重要设备,每年消耗原煤达2亿多吨。锅炉运行效率的好坏对于我国节能具有重大经济意义。当前,我国中小型锅炉广泛采用链条炉排式,锅炉实际运行热效率远低于设计效率。造成热损失大的因素虽然很多,但与工业锅炉上没有建立起一套合理的实际可行的燃烧控制系统有很大关系。针对我国中小型锅炉实际情况,我们对SHL20-1320t/h工业锅炉采用了先进的分布控制,上位机采用1BM-PC计算机,下位机采用了SIMATICS5-605μ可编程控制器,成功地实施了燃烧优化控制,提 Industrial boilers are an important equipment that consumes primary energy and have a large number of applications in our country at present, consuming over 200 million tons of raw coal each year. Boiler operating efficiency is good or bad for our energy-saving has great economic significance. At present, China’s small and medium-sized boilers widely used chain grate, the actual thermal efficiency of the boiler is far below the design efficiency. Although the heat loss caused by many factors, but with industrial boilers did not establish a set of reasonable and practical combustion control system has a great relationship. According to the actual situation of small and medium-sized boilers in our country, we adopt advanced distribution control to SHL20-1320t / h industrial boilers, the host computer adopts 1BM-PC computer, the lower computer adopts SIMATICS5-605μ programmable controller, and successfully implements combustion optimization Control, mention
