METHOD AND DEVICE FOR PURIFYING GASES

摘要

Method for decomposing thermally decomposable components which are present in gases, whereby these gases are led through a heat exchange medium consisting of particles which resist the decomposition temperature, and whereby these gases are heated in said heat exchange medium up to the decomposition temperature of the decomposable components, characterized in that the heat exchange medium is continuously carried around and consequently carried away from a first zone (30) in which this heat exchange medium heats the gases and is again carried to a second zone (31) in which the heat exchange medium is heated, at least partly by the waste gases of the combustion of the decomposable components and/or of the decomposition products thereof and by the remainder of the gases which were further heated by this combustion, which combustion mainly takes place in a combustion zone (32) situated between these zones (30 and 31).
