Zusammenfassung:Loosely stacked fuel (6) is introduced through a charging opening (5) into the furnace (1) of the boiler on a first support (7), and jets (25) of ignition air entraining hot flue gas from the furnace are directed at the surface of the fuel on the support so that the surface layer is ignited and the fuel is partially gasified. The fuel is passed onto a grate (9) located at a lower level on for final combustion. The air from the ignition air jets (25) are permitted, together with the entrained flue gas, to pass down through the loosely stacked fuel (6) and the first support (7) and then to flow off to the furnace (1). The flue gas entrained by the ignition air jets (25) is drawn substantially from a section of the furnace through which flows a mixture of combustion products from the first support and the grate.
