The pulverization of coal is performed in the coal mill, while the hot flue gasses from PH (Hfg 4) are used for preheating and drying of the raw coal. The stream of preheated coal (Fl ph) is then transferred into the rotary kiln burner. A planetary clinker cooler (CC) is used to cool down the clinker from approximately 1400°C to 100°C.

Types Of Plant Maintenance Done In Coal Handling Plant 1. Preventive Maintenance. It involves the systematic inspection of equipment where potential problems are detected and corrected in order to prevent equipment failure before it happens. Maintenance scheduled is based on a time or usage trigger. 2. Breakdown Maintenance

20.13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. …

studies, short-term operations should aim for lower capital cost, while long-life installations should be designed to minimize operating costs and emphasize maintainability. "Operating availability is a function of the design of the processing lines and the ease and type of their maintenance" (Shoemaker and Gould, Modern Mill Design, 1980).

Rapid changes in electricity power markets have increased the production costs of coal-fired power plants and pushed their production to the limits of profitability. For power plants currently in operation, a possible approach to cope with this issue is to introduce novel methods that increase the plant's reliability and availability. Coal mills …

The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

After a year (8760 h) in operation, the availability of coal mills, when the new strategy is applied, is equal to 98.76 % of the availability when the old maintenance strategy is applied—while during the same period, the availability of coal mills, when the proposed remediation-based maintenance is used, is equal to 99.74 %.
