1. By pulling the rising pipes on both sides of the collection box towards the furnace, and then introducing them into the lower part of the drum side, supplemented by insulation at the bottom of the drum, a new furnace structure was successfully used to solve the problem of direct high-temperature flame radiation at the bottom of the drum, avoiding the formation of a heating surface on the top of the furnace; Drum Pack” Defects.
2. The setting of the two wing flue allows the flue gas to smoothly enter the front smoke box, ensuring that the temperature of the front tube plate is the same and avoiding the occurrence of tube plate cracks due to temperature stress.
3. Arched design adopts“ Xi'an Jiaotong University National Science and Technology Progress Second Prize; The latest scientific research achievement shows that the rear arch is low and long, the exit section is reverse inclined, and the front arch has an inclination angle of 45 degrees; Corresponding to the rear arch, forming a clear inversion; α ” Flames are beneficial for the combustion of low-quality coal and have strong adaptability to different types of coal.
4. The design of the grate side sealing structure is advanced and reasonable, with air intake on both sides; Adopting a new type of curved arm screw air regulation structure, the cross-sectional ratio of air regulation and ventilation reaches 99.9%; Flexible adjustment and even air distribution.
5. Design a push-pull gate dust cleaning device, which uses heat-resistant cast iron precision machined sealing structure to effectively prevent secondary combustion deformation and grate air leakage.
