Air supplying method for fluidized-bed boiler, involves supplying air flow from primary air jets and side air jets into furnace, where air flow supplied from primary air jets is stronger than that supplied from side air jets

摘要

The method involves supplying air flow from primary air jets and from side air jets (17) into a furnace (2). The air flow supplied from the primary jets is stronger than the air flow supplied from the side air jets. The primary air jets are placed in a front wall (12) of the furnace. The side air jets are placed in side walls (14, 15) of the furnace. Independent claims are also included for the following: (a) an air arrangement for supplying upper air from an upper air supply level (b) a fluidized-bed boiler.
