Abstract

Pulverizing mills are used to grind raw coal into fine lignite particles, for the preparation of primary fuel to feed the boiler. Hence, it is an important equipment in the Thermal power plants for power production. While in operation, the mills are subjected to unexpected failures, which results in reduced power generation and in turn the productivity. Failure of such critical equipment is a great threat for power production. To overcome this issue, Risk Based Maintenance (RBM) approach is carried out. The Risk Based Maintenance helps in reducing the machinery failure rate resulting from breakdown and managing action priorities. This approach mainly deals with estimating the risk caused by unexpected failures of the components of mill as a function of the probability and the consequence of failure. Maintenance activity for various components of pulverizing mill is prioritized based on the risk level that helps in reducing the overall risk of the equipment. A thermal power station has been selected for performing the maintenance task in pulverizing mill.
