一、引言工业锅炉是工业生产中的通用设备。据统计,全国有20万台锅炉,年耗煤量达2亿吨,约占全国煤产量的三分之一。因此,节约工业锅炉的用煤,是节能工作的重要方面。由于锅炉运行参数较多,各种参数相互影响,情况很复杂,要求又高,因此锅炉的控制也就比较困难,一直以来都以手控制为 I. INTRODUCTION Industrial boilers are common equipment in industrial production. According to statistics, there are 200,000 boilers nationwide, with an annual coal consumption of 200 million tons, accounting for about one third of the national coal output. Therefore, saving coal for industrial boilers is an important aspect of energy conservation. Due to the boiler operating parameters are more, the various parameters affect each other, the situation is very complicated and demanding, so the boiler control is more difficult, has been hand-controlled
