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 ...

Reduce fuel cost by using low-cost low-calorific value coal. Less maintenance and longer bag life. Two types of coal firing are used: 1. Direct Firing 2. Indirect Firing. Direct firing is when coal is milled and is directly fed to the kiln. In indirect firing system, coal is milled and stored and fed to the kiln as needed.

The heating rate may have an important influence on the combustion of pulverized coal under low oxygen concentration. In this work, bituminous coal and anthracite are used for experiments at heating rate of 10 K/min, 20 K/min, or 40 K/min with 5% oxygen concentration. The TG and DTG curves with sample temperature are shown in Fig. 4.
