ChunLei's fired heaters for refineries are engineered with optimized furnace structure, advanced combustion systems and high-temperature resistant materials. Even under high-temperature and continuous operating conditions, these heaters maintain high efficiency and long service life, helping refineries achieve lower energy consumption, improved unit stability and optimized long-term operating costs.


High-efficiency radiant and convection structure for improved thermal efficiency.
The core strength of our refinery fired heater lies in its heat utilization efficiency. The heater adopts a combined Radiant Section + Convection Section design to maximize thermal energy recovery.
In the radiant section, high-temperature flames transfer heat directly to the furnace tubes through radiation, enabling rapid heating of the process medium. The convection section recovers waste heat from flue gas to preheat the feedstock or combustion air.
This structure fully recovers residual heat from flue gas, allowing the overall refinery process heater to achieve a thermal efficiency of 92%–94%, higher than the 85%–88% efficiency of conventional industrial heaters. Fuel consumption can be reduced by approximately 6%–10%. This results in significant annual fuel cost savings, lower energy consumption and carbon emissions, and improved energy efficiency indicators for the entire unit.
High-Temperature Alloy Furnace Tubes for Extended Service Life
Process tubes in industrial fired heaters are subject to high temperatures and harsh chemical environments, which affect equipment service life. ChunLei's fired heaters adopt centrifugally cast heat-resistant alloy tubes, including HK40, HP Micro Alloy, and Cr-Ni heat-resistant alloy steels. These materials maintain outstanding creep resistance above 1000°C, with superior carburization resistance and thermal fatigue resistance.
By optimizing alloy compositions and centrifugal casting processes, we extend the service life of the tubes to more than 100,000 operating hours.
Low-NOx Combustion System for Stable Combustion and Environmentally Friendly Emissions
The combustion system determines the operational stability and emission performance of fired heaters. Our refinery fired heaters are equipped with low-NOx burners and staged combustion technology, which enable precise control of the fuel-air mixing ratio.This ensures stable and uniform flame patterns, eliminates local overheating, and promotes more complete fuel combustion for enhanced heat release efficiency.NOₓ emissions can be controlled at 30–50 ppm, ensuring high heating efficiency while meeting increasingly stringent environmental emission standards.
