Abstract
A furnace, especially a fluidized furnace with a combustion chamber (1) that gas flows up through and that has a gas outlet provided with a second flue (2) and a precipitator (10) for separating solids from the flue gas. The solids end of the precipitator communicates with the second flue, which accommodates a layer (12) of solid matter. The bottom of the second flue communicates by way of a solids-reintroduction line (14) with the combustion chamber. The second flue is a solids cooler and the precipitator is also a filter.
