Improving Coal Pulverizer Performance And Reliability

Improving Coal Pulverizer Performance And Reliability

To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.Oct 01, 2011 The pulverizer configuration usually found in most coal-fired power generation plants is the vertical air swept design, although there are a number of ball tube pulverizers still in service.

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o [email protected]{osti_20939456, title = {Dynamic classifiers improve pulverizer performance and }, author = {Sommerlad, R E and Dugdale, K L}, abstractNote = {Keeping coal-fired steam plants running efficiently and cleanly is a daily struggle.
