PCT No. PCT/FI81/00054 Sec. 371 Date Mar. 8, 1982 Sec. 102(e) Date Mar. 8, 1982 PCT Filed Jul. 6, 1981 PCT Pub. No. WO82/00187 PCT Pub. Date Jan. 21, 1982.The invention concerns a heating boiler operating on solid, comparatively finely divided fuel, such as chips or peat, and which is used to produce hot water or steam. The boiler comprises a furnace, in which the grate consists of a shell-like burning basket, which can be placed in rotary motion about its substantially horizontal axis. The rotating of the burning basket may be arranged by connecting to the basket a tubular arm provided with a gear wheel and which is connected to a motor placed outside the boiler. The arm then simultaneously serves as duct through which the fuel is introduced into the burning basket. The purpose of the rotating burning basket is to boost the combustion reaction so that comparatively wet fuel can be used in the boiler. The combustion may furthermore be boosted by placing the burning basket in the furnace in a housing having as its extension a cyclone constituting a helical exhaust duct for the flue gases, which sets the gases at high temperature into strongly turbulent motion.
