Maintenance of coal mills is an important part of ensuring the efficient and reliable operation of a 210 MW power plant.
Coal mills are used to grind and pulverize coal into fine powder, which is then used as fuel in the boiler. Regular maintenance of coal mills can help to prevent downtime, reduce maintenance costs, and ensure that the power plant operates at maximum efficiency.
Monitoring: Coal mills should be monitored regularly to ensure that they are operating within their designed parameters. Monitoring can include measuring temperature, pressure, and airflow, and comparing these measurements to the manufacturer's specifications.

In addition to these maintenance activities, it is important to have a comprehensive maintenance program in place, which includes regular inspections, preventive maintenance, and corrective maintenance. This can help to ensure that coal mills of 210 MW units operate efficiently and reliably, minimizing downtime and reducing maintenance costs.
