METHOD AND SYSTEM FOR BURNING SOLID PULVERIZED FUEL Russian patent published in 1997 - IPC

FIELD: power engineering; pulverized fuel combustion. SUBSTANCE: basic component in solid pulverized fuel combustion process is dust fluidizing unit 1 affording subsequent transfer of fuel over process channel with minimal content of air-carrier in it. Fluidized stream of fuel 4 goes to dust heating unit 5 wherein it comes in contact with high-temperature gaseous coolant 6. Then heated gas-dust mixture 10 arrives at gasification unit 11. Upon gasification, modified fuel 12 is passed to burner 13 to be burned together with hot air 14. EFFECT: improved efficiency of fuel combustion. 3 cl, 2 dwg
