DYNAMIC STOCHASTIC MODELS BY THE FEATURE OF "RAW COAL FEEDER ROTATION SPEED - FLUE GAS TEMPERATURE IN THE FURNACE SYSTEM REVERSING CHAMBER" IN STEAM GENERATION
The article treats the application of a known Box - Jenkins method for steam generation process identification. The object of the study is a furnace unit, which is a very complex and interconnected system. We describe it as a dynamic stochastic object with uncontrollable perturbation influence. The temperature of flue gases in the reversing chamber is determined to be an indirect parameter characterizing heat emission of air mixture combustible dust. Experimentally and with the application of statistical methods, we obtained a mathematical model allowing to determine the effect of the raw coal feeder rotation speed on the flue gas temperature in the reversing chamber of the furnace unit on left and right sides. Rotation speed of raw coal feeders refers to control actions in steam production. The developed model can be used for forecasting and controlling the temperature of flue gases in the reversing chamber of the furnace unit on the left and right sides.
