Abstract

In a process for separating the bed material and to increase the heat transfer in an incineration plant operating on the circulating fluidised bed principle and a corresponding finned-tube incineration plant for implementing the process with a separation and return device parallel to the combustion chamber to separate and return the bed material into the combustion chamber, the stream of flue gas from the combustion chamber with the material conveyed with it is deflected in the gravitational direction and subsequently against gravity so that the coarse material is separated and returned and the fine material is used for transferring heat to the downstream heating surfaces. To this end, there is a deflection wall (14) partly separated by an intermediate wall (4) with a separation chamber (2) and a return device (9), where these devices form part of the descending and rising pipe system of the boiler body.
