Abstract THe complex utilization of coal burning boiler smoke and ash slag features the sulfur circulation process to produce sulfuric acid and phosphoric acid as well as sulfur fertilizer and phosphate fertilizer, to convert ash slag into Se and Ge rich anticancer glass fertilizer and functional glass fertilizer, asbestos fiber, heat insulating board, artificial timber, light energy saving wall board and other products. The produced fertilizers may be further compounded with nitrogen fertilizer, potash fertilizer and boron fertilizer to produce anticancer functional compound fertilizer. The present invention can realize no waste slag and no pollutant gas exhaust.
