Abstract

The boiler combustion chamber (1) contains one or more vertical shafts (9) which are closed gas-tight at the top and issue at the bottom over the topside (8) of the eddy layer. The shaft walls (10) contain fluid-cooled pipes (12,13) which continue down through the eddy layer to distributor pipes (17) near the chamber's perforated bottom wall (3). The shaft's total cross-sectional surface is so much smaller than the eddy layer's top side that exhaust gases from the layer can flow upwards without hindrance through the combustion chamber between the shaft walls and the boiler's side walls (2'). Cooling of the shaft walls prevents ignition of fine fuel particles over the eddy layer, and permits usage of mechanical fuel feed extending across the whole combustion chamber's length.
