How to Protect Grates and Furnace Walls When Burning High-Calorific-Value, Light Solid Waste
How to protect grates and furnace walls when burning high-calorific-value, light solid waste in waste incinerators where furnace temperatures are too high
When burning high-calorific-value, light solid waste, the problem of protecting grates and furnace walls from excessively high furnace temperatures in waste incinerators needs to be effectively addressed through multi-dimensional measures such as material upgrades, structural optimization and operational control:
- Selection of refractory and insulation materials
Refractory layer of furnace walls: use high-alumina bricks or silicon carbide composite materials as the lining to resist erosion by high-temperature molten slag;
Grate material: use high-temperature alloy steel;
- Structural design and cooling system
Enhanced heat dissipation design
Combustion chamber optimization: adopt a stepped grate plus rotating arch structure to promote tumbling of materials and avoid local accumulation and overheating;
- Temperature control and operation management
Precise regulation of air volume to avoid overtemperature; waste heat recovery and utilization: install waste heat boilers or steam generators; real-time monitoring and maintenance
- Process adaptability adjustment
Raw material pretreatment and layered feeding control: adopt a multi-stage feeding system
Through the above comprehensive measures, long-term stable operation of grates and furnace walls can be achieved under high-calorific-value working conditions, while improving energy utilization efficiency.
