Performance of the pulverizer is critical to: Combustion efficiency; NO x and CO reduction; Unit availability; Many power operator have switched to the coal supply from the spot market, and turn to low grade coal. Low grade coal have higher ash content and moisture that could lead operation problems, i.e. high FEGT, boiler slagging and fouling ...
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. The classification function plays the important role of ensuring that only fine particles are sent to the boiler.
This study shows the performance of a currently running vertical roller coal mill (VRM) in an existing coal-fired power plant. In a power plant, the coal mill is the critical equipment, whose ...
Coal pulverisers' performance optimisation is an important process in power generation plants. Pulveriser operation is costly; reliability and availability is key to power generation and cost reduction is achieved by the optimal performance of associated plants. The objective of
