This paper introduces the 2020829ensp0183enspa mathematical model of vertical shaft mill in thermal power plant. The model is based on the dimension mass balance SMB of coal mill and the overall mass and energy balance of mill. The model has been verified by the data collected in the mill model field test of 660MW Unit, and the research design and evaluation of the dynamic performance of the mill are carried out

The monitoring and diagnosis of coal pulverizer system is the key to the safe operation of power plant. In order to obtain a large number of fault samples effectively, the traditional data-driven fault diagnosis method often leads to low fault identification rate and even misjudgment of primary air system analysis due to the imbalance between fault data samples and normal data samples

2007130ensp0183enspat is located on the top of the mill shell. The air coal mixture 5 enters the classifier through the corner blade, which makes the air flow generate vortex. The coarse particles 8 on the impact wall are intercepted and returned to mix with the raw coal on the rotary table. Fine particles 6 are suspended in the air stream and leave the mill

Finally, taking the estimation of coal outlet mass flow as a new control variable, the inference predictive control method is used to solve the control problem of coal mill. The simulation results show that the new control method can shorten the delay time of coal preparation system and accelerate the response of boiler to AGC command

The pulverizer used in coal-fired power plant is modeled from the perspective of controller design, rather than educational simulator. By re studying the mass balance and heat balance model, the mass flow rate and outlet temperature of coal are modeled. The model parameters are identified by using the archived data in the power plant database
