Pulverized coal producing processes are widely used in thermal power stations, cement and iron-smelting industry. Many accidents and protection techniques have been reported by former investigations [1-3]. Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and

Coal mills have a significant influence on the reliability, efficiency, and safe operation of a coal-fired power plant. Coal blockage is one of the main reasons for coal mill malfunction. It is highly essential to accurately detect the critical blockage in coal mills to ensure a safe and stable operation of the unit. Taking advantage of unsupervised learning methods and historical process data ...

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal …

The Shell coal gasification process (SCGP) uses an up flow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. 8.5).The up flow arrangement allows separation of syngas and slag largely within the reactor itself.

China is the largest energy consumer in the world and its main energy resource is coal. With the increase in the depth and intensity of coal mining activities, a variety of coal-rock dynamic disasters such as coal and gas outbursts, rock bursts, and large-scale pressure on stope, have become more serious and safety production problems have also arisen [1,2].

Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called "coke" remains.
