How to Purchase the Right Boiler Grate Bars During Maintenance?
Boiler grate bars are critical components directly involved in fuel combustion, widely used in chain grate steam boilers, hot water boilers, thermal oil boilers, and other thermal equipment. To ensure the boiler operates efficiently, regular inspection and maintenance of the chain grate and its components are essential.
Common Chain Grate Issues and Solutions
- Chain Grate Movement Failure: Large fuel particles or external forces can cause the grate to jam, leading to intermittent movement or complete stoppage. Severe cases may result in broken fuse links or damaged transmission mechanisms. Immediate inspection and troubleshooting are required
- Chain and Gear Misalignment:Prolonged operation can cause significant wear, leading to misalignment. Timely chain replacement is necessary.
- Chain Beam Bending: External forces or overload can bend the beams, requiring immediate replacement.
- Grate Deviation During Operation: Improper adjustment of the front and rear axles during installation can cause unstable grate movement.
- Fuel Coking on the Grate: Long-term use of low-quality coal or high-oil-content fuel can lead to caking on the grate surface. Regular cleaning is recommended.
Purchasing New Chain Grate Spare Parts
When replacing essential parts like grate bars, it’s crucial to provide suppliers with accurate details to avoid confusion. Below are key measurements for a 20t/h chain grate steam boiler:
1. Left and Right Boiler Grate Bars
Measure the length, width, height, and positioning dimensions. Note that left and right bars may look similar but have different installation orientations.
2. Middle Grate Bar
Provide detailed measurements as illustrated.
3. Large Grate (Fish Scale Type)
Due to variations between manufacturers and batches, measure the length, width, height, hole spacing, hole diameter, and other parameters.
4. Chain
Specify the length, number of sections, thickness, and other requirements. For example, a 20m chain with 125 sections.
5. Boiler Slag Stopper/Ash Remover
Measure the arc length and the distance between endpoints.
6. Roller
Provide the overall length.
7. Bushing
Include outer and inner dimensions.
8. Shaft
Specify the dimensions and overall length.
9. Grate Buckle
Provide the end face diameter and connecting part diameter.
10. Side Seal Plate
Measure the overall length, height, and width, as designs vary.
