Coal Combustion

It is kept at low temperature, limited to about 373 K, for reasons of safety against ignition and explosion in the mill and in the powdered coal transport pipeline between the mill and the burners. The rest of the combustion air, which can be preheated to higher temperatures, is injected separately and admixed with the already ignited coal particle-laden jet in the combustion chamber.

How to Match Oil Filtration to Machine Requirements

 · For instance, during normal operating speeds, fine fly ash will pass freely through machinery bearings in a coal burning electric power station without causing damage. However, when the rotational speed drops to five to 10 rpm, the bearings in a steam turbine are susceptible to excessive wear due to reduced film thickness and the associated reduction in the clearance for the contaminants.

Coal-fired power station

The 4 main types of coal-fired power station in increasing order of efficiency are: subcritical, supercritical, ultra-supercritical and cogeneration (also called combined heat and power or CHP). [42] Subcritical is the least efficient type, however recent innovations have allowed retrofits to older subcritical plants to meet or even exceed efficiency of supercritical plants.
