Characteristics of RB Control Loop of Large Lignite Power Plant Boiler and Analysis and Comparison

In recent years, lignite has been widely used as an important reserve energy in China. In view of the characteristics of lignite, such as high moisture content, high volatile content and low calorific value, in order to achieve the best expected effect, a plant has carried out many RB experiments. Reasonable use of the boiler itself heat storage, through constant adjustment of water, coal and other inertial links, so that the unit safety and stability to low load. According to the characteristics of lignite boiler, a series of RB logic rationalization control suggestions are put forward.
