| titleOfInvention | Circular flame ultra-low NOx burners for ethylene and styrene plants |
| abstract | A circular flame ultra-low NOx burner for ethylene and styrene devices belongs to the technical field of heating furnace burners. The upper part of the burner main body is provided with a primary combustion zone (18) and a secondary combustion zone (17) in sequence from bottom to top; The upper end of the outer gas pipe (1) extends into the primary combustion zone (18), and the upper end of the outer gas pipe (1) is arranged on the side of the secondary combustion zone (17), and the gas is sprayed to the secondary combustion zone (17), and the tail gas pipe (4) It is arranged between the primary combustion zone (18) and the secondary combustion zone (17), and the upper end of the exhaust pipe (4) is provided with a burner, and the exhaust gas is sprayed to the secondary combustion zone (17). The inner gas pipe and the outer gas pipe of the utility model inject the gas in stages, and the tail gas pipe sends the tail gas after the primary combustion zone combustion to the secondary combustion zone, and adopts the combustion grading and flue gas recirculation technology to suppress the generation of NOx . |
