NUMERICAL SIMULATION OF BURNERS WITH THERMAL PRETREATMENT OF THE PULVERIZED COAL STREAM at THERMAL POWER PLANTs /
The problem of replacement of masut is actual at kindling and illumination of a jet of furnace of boiler by cheap coals of Kansko-Achinsk basin, which cost more than 10 times less cost of liquid fuel - masut. The work is devoted to the study of the burners with thermal pretreatment of a pulverized coal stream to burn brown coal of Kansko-Achinsk basin at thermal power plants. Numerical simulation of a burner muffle to specify the design and determine required operating regimes of the object under study is performed. The findings will provide practical recommendations to develop energy efficient universal burners.
