A new energy material enterprise in Sichuan produces 80,000 tons of petroleum coke powder annually. It uses our company's 2500 fuel hot air furnace as the core heat source equipment, and the supporting rotary drying system realizes deep drying of petroleum coke moisture from 15% to 1%.
As the core heat source of the petroleum coke drying system, the fuel hot air furnace generates high-temperature clean hot air (adjustable from 180-650℃) by burning fuel, directly or indirectly heating the wet petroleum coke in the rotary kiln/drum. The equipment has a thermal efficiency of up to 92%, which saves more than 30% energy compared with traditional coal-fired hot air furnaces. The moisture content is deeply dried from 15% to less than 1%, meeting the raw material standards of high-end carbon products such as negative electrode materials.
Equipment technical features
1. Combustion system optimization
Using heavy oil catalytic combustion technology, the thermal efficiency reaches 91%
Dual-channel swirl burner ensures temperature field uniformity (±2℃)
Gradual utilization of tail gas waste heat (preheating combustion air to 150℃)
2. Drying process control
Multi-section temperature control system (adjustable from 200-450℃)
Oxygen content monitoring and linkage damper adjustment
Explosion-proof design meets the explosion-proof requirements of carbon powder
Customer feedback: "The combustion furnace operates stably and reliably, with a high degree of automation, which greatly reduces the intensity of manual operation. At the same time, its excellent energy-saving performance saves us more than 800,000 yuan in fuel costs annually, and the nitrogen oxide emission concentration is less than 80mg/m³, which fully meets environmental protection requirements."
This case fully verifies the technical advantages of fuel combustion furnaces in the field of petroleum coke drying, and has achieved significant economic and environmental benefits. It provides efficient and environmentally friendly heat source solutions for the carbon industry.
