Abstract

This invention deals with a method of burning crushed or lump-sized combustible material, such as limestone, dolomite, magnesite or a similar material, in an annular shaft kiln having an annular outer shaft and an inner shaft, where the annular and the inner shafts are alternatively charged with fresh air and combustion gases, or are connected with the exhaust gas system. Furthermore, the invention deals with an annular shaft kiln for carrying out this method, which has a shaft insert that is open at the top, whereby the combustion material is selectively fed into the annular shaft formed around the shaft insert, or into the inner shaft which is formed inside the shaft insert. In a first operating position, the inner shaft adjacent its upper end is connected with the exhaust gas system, and combustion gas and combustion air are fed into the outer annular shaft. In a second operating position, the inner shaft is fed with the combustion air and the combustion gas, while the annular shaft adjacent its upper end, is connected to the exhaust gas system. Thus, in the first operating position, the annular shaft has air passed it and the inner shaft has gas flowing through it in counter flow, the flows being parallel, and in the second operating position the annular shaft has gas passed through it in counter flow and the inner shaft has air passed through it in parallel flow.
