The influence of pulverizing process parameter, such as electrical current of the driving motor, mill capacity, boiler production, coal types on mill vibration are investigated to identify the potential malfunction of beater wheel mills and their associated components for predictive maintenance purposes.
Entrainedflow gasifiers have the ability to handle practically any coal feedstock and produce a clean, tarfree syngas. Given the high operating temperatures, gasifiers of this type melt the coal ash into vitreous inert slag. The fine coal feed can be fed to the gasifier in either a dry or slurry form. The former uses a lock hopper system ...

The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually.
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are:
