Problems solved by technology

During the actual operation, it was found that the inner wall was severely corroded and worn, and the furnace was forced to be shut down for maintenance, which caused losses to production
Through analysis, it is found that the causes of damage are halogen element corrosion and alkali metal corrosion. This depends on the content of halogen elements and alkali metal elements in the gasified coal, resulting in different corrosion situations. To deal with this situation, it is necessary to Select the corresponding inner wall material for the elemental content of the production coal tested at the beginning, and the selected inner wall material is equivalent to the limited coal type, which reduces the coal type adaptability of the gasifier
Once the coal type changes, the inner wall will be corroded, and the rotation of the furnace grate will drive the coal and coal ash to rub against the inner wall, which will cause the water jacket to leak, and the gasifier will be forced to stop for maintenance, causing losses to production
