Operating Conditions and Lining Requirements of Flare Combustion Chambers
Flare combustion chambers are critical equipment in petrochemical plants, responsible for processing combustible waste gases. They must ensure environmentally compliant emissions while preventing the accumulation of flammable gases that pose safety risks. Therefore, the refractory lining must have high-temperature resistance, thermal shock resistance, and corrosion resistance to ensure long-term stable operation.
Challenges in Flare Combustion Chambers:
Severe thermal shock: Frequent start-stop cycles subject the lining to rapid heating and cooling.
Flame erosion: The burner area is directly exposed to high-temperature flames, requiring linings with high wear and erosion resistance.
High insulation requirements: Reducing heat loss improves combustion efficiency and lowers operating temperatures.
Lining Design:Walls and roof: Refractory ceramic fiber blocks serve as the insulation layer, effectively reducing the outer shell temperature.
Around the burner: High-strength refractory castables enhance resistance to flame erosion and mechanical impact.
Advantages of CCEWOOL® Refractory Ceramic Fiber Blocks
CCEWOOL® refractory ceramic fiber blocks are made from folded and compressed ceramic fiber blankets and are secured using metal anchors. Their key advantages include:
High-temperature resistance (above 1200°C), ensuring long-term stable insulation.
Excellent thermal shock resistance, capable of withstanding repeated rapid heating and cooling cycles without cracking.
Low thermal conductivity, offering superior insulation compared to refractory bricks and castables, reducing heat loss through the furnace walls.
Lightweight construction, weighing only 25% of refractory bricks, reducing the structural load on the flare combustion chamber by 70%, thereby enhancing equipment safety.
Modular design, allowing for faster installation, easier maintenance, and minimized downtime.
Installation Method of CCEWOOL® Refractory Ceramic Fiber Blocks
To enhance the stability of the furnace lining, a "module + fiber blanket" composite structure is used:
Walls and roof:
Install ceramic fiber blocks from bottom to top to ensure even stress distribution and prevent deformation.
Secure with stainless steel anchors and locking plates to ensure a tight fit and minimize heat leakage.
Fill corner areas with ceramic fiber blankets to enhance overall sealing.
Performance of CCEWOOL® Ceramic Fiber Blocks
Energy savings: Lowers the outer wall temperature of the combustion chamber by 150–200°C, improving combustion efficiency and reducing heat loss.
Extended service life: Withstands multiple thermal shock cycles, lasting 2–3 times longer than traditional refractory bricks.
Optimized structural design: Lightweight materials reduce the steel structure load by 70%, enhancing stability.
Reduced maintenance costs: Modular design shortens installation time by 40%, simplifies maintenance, and minimizes downtime.
CCEWOOL® refractory ceramic fiber block, with their high-temperature resistance, low thermal conductivity, thermal shock resistance, and lightweight properties, have become the ideal choice for flare combustion chamber linings.
