Abstract: A self-cleaning, high heat transfer wood or coal stove includes an interior cylindrical squirrel-cage configured fuel grate comprised of parallel air-conducting pipes for heating forced cold air. This arrangement of pipes not only provides for a self-cleaning stove interior due to the cyclical condensation and combustion of deposited effluents produced by combustion, but also greatly enhances the heat transfer capability of the stove by increasing the surface area available for heat exchange. The cyclical condensation and combustion is effected by incrementally rotating the interior cylindrical fuel grate by turning, using a handle inserted into one of a plurality of rod sockets which reside on the front of the stove. The stove of this invention is constructed with separate doors for convenient fuel loading and ash removal, and the fuel loading door is disposed to engage the combustion chamber opening with an air-tight and secure fit.

Abstract: 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.
