Coal Feeder Maintenance Checklist for Thermal Power Plants

By Willam Jerry on October 10, 2026

A coal feeder does one job: deliver the right amount of coal to the mill, steadily. When it does not, the boiler feels it quickly, through unstable firing, load swings and trips. Most feeder problems are not sudden. A belt drifts off centre, a skirt seal wears, a load cell drifts, coal starts to bridge in the inlet, and each one is visible on a walk-down before it becomes a trip. This 33-point coal feeder maintenance checklist follows the coal path from inlet to discharge so nothing gets missed. OxMaint AI maintenance management software turns each stop into a scheduled inspection with recorded findings and follow-up work orders.

Coal Feeder Maintenance Checklist for Thermal Power Plants.

Missed feeder checks show up as unstable coal flow, drifting feed rate and avoidable trips. OxMaint AI connects feeder inspections, issues found, work orders and recurring PM in one platform, so every shift check is recorded and every defect gets an owner and a due date.

The Coal Feeder Walk-Down Checklist

Follow the route from the hopper to the discharge and tick each item as you go. Tags show how often each check is typically done. Critical marks safety items, so never skip them. Intervals are typical; your manufacturer's manual and plant procedures decide the final schedule. Book a demo to see each stop become a scheduled round.

Six Feeders, Four Shifts, One Paper Checklist. Who Checked Feeder 3B on Tuesday?

OxMaint AI assigns each round by feeder and shift, collects readings and photos on a phone, flags missed checks and keeps the history per asset, so the answer is always on record.

Coal Feeder Troubleshooting: Symptom to First Check

When something goes wrong, start with these checks before opening anything up, and always isolate and lock out first. Start free and log faults against each feeder.

Low or no coal flow
Check inlet gate, bridging or rat-holing in the hopper, wet coal and a blocked chute.
Belt drifting or mistracking
Check belt tension, idler alignment, loading and build-up on pulleys.
Feed rate drifting from setpoint
Check zero, load cell, speed sensor and skirt seal condition, then recalibrate per procedure.
Motor overload or trip
Check belt jam, bearing condition, gearbox oil and an overloaded or sticking drive.
Coal dust or spillage
Check door gaskets, seal air and skirt boards, and clean spills promptly.
Unusual noise or heat
Check bearings, gearbox, idlers and coupling, and trend temperature over time.

Frequently Asked Questions

What should a coal feeder maintenance checklist include?
Inlet and hopper, belt and skirts, drive, gearbox and bearings, weighing and calibration, discharge and seals, and safety and housekeeping. Start free and use the template.
How often should a coal feeder be inspected?
Many plants do a quick check every shift, with deeper checks weekly and monthly and calibration and internal inspection at outages, subject to the OEM manual. Book a demo of the schedule.
Why does coal feeder calibration matter?
Feed rate accuracy affects combustion stability. Zero and span checks per your procedure help keep measured and actual coal flow aligned. Start free and schedule calibration.
What are common coal feeder problems?
Coal bridging, belt mistracking, worn skirts and seals, drifting calibration and bearing or drive faults. Book a demo of fault tracking.
How does a CMMS help with coal feeder maintenance?
OxMaint AI schedules each round, records readings, turns defects into work orders and keeps history per feeder. Start free and see it work.

Keep Coal Flowing and Every Check on Record.

Schedule the rounds, record the findings and close every defect. Start with one feeder and see how much clearer the picture gets.
