Review of control and fault diagnosis methods applied to coal
2015年8月1日 Mill problems originate mainly due to poor controls or faults occurring within the milling system As discussed by GQ Fan and NW Rees [3], the control of mills remains very simple in most of the power plants due to the fact that the mill system is highly nonlinear with strong coupling among the variables and it is very difficult to measure some important The directfired system with duplex inlet and outlet ball mill has strong hysteresis and nonlinearity The original control system is difficult to meet the requirementsStructure of duplex inlet and outlet ball mill systemIn order to solve the problem that the output of ball mill pulverizing system is difficult to directly measured in thermal power plant with double inlet and double outlet ball mill pulverizing system which is a large delay, strong nonlinear system It introduces the pruning method to improve the incremental least square support vector machine's sparsity that based on the incremental least Direct Blowing Pulverizing System Modeling Based on IPLSSVM2016年8月1日 The established coal mill model is based on the following assumptions: (1) the process of coal grinding is simplified by disregarding the separation of coal particles; (2) the grinding and delivery of pulverized coal are divided into two stages in the mill; and (3) pulverized coal sizes at the outlet is neglected in the model, and only raw coal and pulverized coal exist in Modeling and control of ball mill system considering coal moisture
