A health check-up of CHP (Coal Handling Plant) and AHP (Ash Handling Plant) equipment is a systematic inspection and performance assessment carried out to ensure safe, reliable, and efficient operation. It focuses on identifying wear, misalignment, overheating, leakages, vibration, and abnormal operating conditions.
For CHP equipment—such as conveyors, crushers, feeders, transfer points, and stacker-reclaimers—the health check includes inspection of belts and rollers, gearbox and motor condition, lubrication systems, chute blockages, dust suppression systems, and safety interlocks. Special attention is given to spillage, belt tracking, bearing temperature, and vibration levels.
For AHP equipment—including ash slurry pumps, pipelines, hydro-ejectors, silos, compressors, and valves—the check-up covers pump performance, seal and gland condition, pipeline erosion/leakage, ash concentration, hopper discharge, and instrumentation health.
Regular health check-ups help in early fault detection, reduction of forced outages, improved plant availability, extended equipment life, and enhanced safety, thereby supporting efficient and uninterrupted power plant operation.
