coal mill operation in pulverized fuel

Pulverized Fuel Boiler an overview ScienceDirect Topics

Coal mills can also be used for reducing harmful emissions from the boiler. Appropriate modernization can not only decrease the sulfur content in the pulverized fuel, and thus the SO 2 emissions, but also the emissions of arsenic and mercury. An important objective of modernization of the grinding systems is to equalize fuel and air streams to individual burners, which is needed to ensure the required NOx

Pulverized coal-fired boiler Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

A Comparison of Three Types of Coal Pulverizers

Figure 5 shows the installation of a vertical roller mill in a typical pulverized fuel system. These mills are designed for pressurized operation since primary air fans are located upstream of the mill. Similar to the BTM, pressurized seal air is also used to prevent leakage of coal dust from the mill and to protect bearings in the grinding rollers.
