Abstract
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.

The purpose of RB test process of unit is to ensure long-term safe and stable operation of unit. Therefore, the relevant parameters of RB test should consider the condition of long-term operation of unit. Therefore, the parameter adjustment and optimization before RB test and the more stable coal type should be adopted in RB test process. Different RB parameter loops are adjusted according to different coal types and different combustion modes.
