There are varieties of critical equipments in Coal Handling Plants. These components require routine inspection to ensure their integrity. The purpose of the inspection is to identify any degradation in the integrity of the systems during their service life and to provide an early warning in order that remedial action can be taken before failure occurs. Assessing the condition is necessary to optimize inspection and maintenance schedules, of Coal Handling Plant to make decisions and to avoid unplanned outages.

Importance of CBM for CHP

To maintain an efficiently operating unit and avoid failure of critical equipment, it is necessary to maintain the critical parts of that equipment. The effect of planned maintenance is depending upon the methods used for maintenance. The combination of corrective preventative and condition based maintenance will required to apply for Critical Equipments. This type of maintenance policy and strategy will improve performance of CHP through availability of Critical Equipment. The basic layout of Coal Handling Plant is shown by block diagram. (See Fig. No 1) the coal is unloaded at unloading station and transported by conveyors to crushing and screening plant via transfer house. After crushing required quantity of coal is transported to bunker via transfer house and remaining coal is stored in stockyard. This coal is reclaimed as per requirement. There are different streams for transporting of coal. The streams are operated as per requirement. Some of the CHP’s are now days are operating beyond their design lives. Working conditions in CHP are dusty, dirty and often wet conditions. So there is a constant quest to improve machine uptime and avoid unplanned maintenance. A plant, which supply of coal to boilers having capacity of 750 tones per hour failed to fulfill need will loss generation of 0.6 MU for one hour. This cost 1.20 Core of Rupees.
