Application of Model-Based Deep Learning Algorithm in Fault

The coal mill is one of the important auxiliary engines in the coal-fired power station. Its operation status is directly related to the safe and steady operation of the units. In this paper, a model-based deep learning algorithm for fault diagnosis is proposed to effectively detect the operation state of coal mills. Based on the system mechanism model of coal mills, massive fault data are

In addition there is heated combustion air fed to the mill to transport the pulverised coal, and the secondary air supply as shown in Fig. 4. Grinding. The grinding function reduces coal fed into the mill into a dust with particles of the size required for combustion. There are two main types of mill in common use: the spindle type and the drum

the coal pipe. Conversely, the flame stability can suffer, if the coal/air mixture becomes too lean. Two factors helped deal with these problems. One is finer coal pulverization, produced by the pulverizer at low primary air flow/coal throughput, and another was the relatively high volatiles content in the coal (34-36%).

Grinding elements maximise pulveriser operating | Engineer

Poor pulveriser grinding efficiency can be a contributing factor to poor combustion efficiency at the furnace and a myriad of downstream effects. Coal pulverisation is viewed as a high wear process and generally considered the 'key' to combustion performance; thus the primary consideration of many when it comes to optimising system performance.

MPS mill is a type of mill known as an applied force mill, meaning that the force used in this type of mill has both magnitude and direction. MPS mills utilize large tires as their grinding media and are primarily used for the pulverizing of coal. Bowl mills are very similar to MPS mills and come in two main designs: deep bowls and shallow bowls.
