Abstract

Method in burning solid fuels of different types in a furnace (10). The fuels is supplied to the upper end of an inclined grate (11) and is burnt thereon while primary air, possibly mixed with flue gas, is blown from below through the grate and the fuel bed (36) thereon to provide a zone of suspended fine fuel particles above the fuel bed. Unburnt material entrained into the escaping flue gas is separated from the flue gas and returned to the furnace for final combustion. Air and/or flue gas is blown into the upper portion of the grate transversely of the grate at a high pressure to provide an air or flue gas curtain at the location (12) of supplying the fuel while blowing-up existing fine fractions of the fuel from the fuel bed. At the same time the returned material together with air and/or flue gas is blown into the fuel bed in the lower portion of the grate for blowing-up remaining fine fractions of the fuel bed while blasting and stirring the fuel bed and simultaneously lowering the temperature of the hottest combustion zone located on the lower portion of the grate.
