Coal Feeder Conveyor Belt for Power Plant Weigh Feeder
The Coal Feeder Belt is a critical component in thermal power plants and coal handling systems. It is not just a ordinary conveyor belt, but a precision-engineered device that integrates weighing, conveying, and control functions. It directly impacts boiler combustion stability, especially in power generation applications.
Key Features at a Glance
| Feature | Description |
|---|---|
| Core Function | Accurate Feeding & Weighing – Transports raw coal from the bunker to the pulverizer at a controlled rate, while continuously weighing the material. It is a key element in the plant's DCS (Distributed Control System). |
| Design | Endless (Spliceless) – Modern feeder belts are vulcanized as a continuous loop without mechanical fasteners, eliminating joint-related failures. Sidewall (Profiled) – Equipped with corrugated edges to prevent coal spillage that could interfere with weighing accuracy. |
| Common Material | Fire-Resistant Rubber – Most power plants require belts to meet flame-retardant standards (e.g., IS 1891 Part V), replacing conventional wear-resistant (M-24) rubber for safety. |
| Typical Specs | Thickness: 5–10 mm Width: up to 1168 mm Length: custom-made based on feeder dimensions. |
Our Product Advantages
1. The seamless skirt edge is firmly attached without peeling off - through the use of high-frequency vulcanization technology, the skirt edge is seamless and extremely sturdy.
2. Usage efficiency has been doubled - using polyester fiber fabric as the framework layer, it is highly resistant to pressure, does not deform or stretch.
3. Smooth operation - The infrared shaping process is adopted, resulting in flat and secure joints.
4. Strong Manufacturer - A professional manufacturer and research and development enterprise, with international SGS factory certification.
Working Principle – More Than Just Conveying
The feeder belt operates with high precision:
- Raw coal drops from the overhead hopper onto the belt.
- An adjustable metering gate levels the coal bed to ensure a constant cross-sectional area.
- Load cells beneath the belt, combined with belt speed sensors, calculate the instantaneous feed rate.
- This signal is fed back to the control system for closed-loop regulation.
This accuracy directly affects pulverizer vibration, coal fineness, and overall combustion efficiency
Procurement & Design Considerations
When selecting a coal feeder belt, prioritize the following:
- Fire Resistance – Confirm compliance with relevant flame-retardant standards (mandatory in most thermal plants).
- Dimensional Accuracy – Verify belt circumference, width, and sidewall height against the original feeder specifications.
- Tensile Strength – Check the carcass rating (e.g., EP400/3) to ensure it meets the required load capacity and service life.
