Abstract: The new-type high-efficiency combustion furnace for sulfur recovery includes main combustion furnace, reheating furnace and exhaust incinerator. It is mainly used for sulfur recovery at natural gas purification plant, petrochemical plant and coal-fired electricity generation plant. It is the key equipment in the Claus sulfur recovery process system. This paper introduces the key technological parameters, such as furnace temperature, furnace volume, designed pressure, and furnace wall temperature. Ring wall protection technology is adopted to effectively control the inner wall temperature in high-temperature furnace lining. Skid-mounted integration technology is developed to ensure long-term operation of production facility and reduce discharge of pollutants. The overall technology level is better than that of imported burner, breaking the monopoly of foreign products for sulfur recovery combustion furnace and ensuring the quality of natural gas surface construction projects.

Key words: sulfur recovery, combustion furnace, high-temperature combustion, localization
