Abstract

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.
