Pulverised Coal an overview ScienceDirect Topics

Pulverized coal is used in many utility boilers. Due to the small particle size, pulverized coal can be transported pneumatically. Coal particles contain four major components: moisture, volatiles, char, and ash. When heated, the moisture is dried and the volatiles are devolatized. The volatile vapor mixes with oxygen and the mixture burns.

Pulverised Coal Combustion with higher 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 C.

Pulverized Coal Firing Systems Testing & Diagnostics

Typical Pulverized Coal Investigation Scenario: A pulverized coal fired boiler experiences furnace slagging and elevated carbon in ash after changing coal suppliers. An investigation to remedy this problem may involve the following activities: Site Visit & Testing: A series of pulverized coal [PC] sampling tests are conducted on each pulverizer

Numerical simulations of pulverized coal combustion

Coal is an important energy resource for meeting the further demand for electricity, as coal reserves are much more abundant than those of other fossil fuels. In pulverized coal fired power plants, it is very important to improve the technology for the control of environmental pollutants such as NOx, SOx and ash particles including unburned carbon.
