Separator of solid particles from steam-gas mixture

The present invention is related to the separator (dust chamber) for separating solid particles from vapor-gas mixture, particularly to the structure of the dust chamber belonging amongst installation of the plant processing the fossil fuels or materials containing organic matter. The dust chamber for separating solid particles from vapor-gas mixture comprises main body with inner refractory lining arranged to the inner surface of said main body, first and second stage cyclones, lamella compensators, dust removal conduits and inlet conduit of the vapor-gas mixture into the first cyclone. The main body of the dust chamber is manufactured in all height from the cylinder of equal diameter and first and second stage cyclones are placed outside of the main body of the dust chamber. For the refractory lining of the main body of the dust chamber and first and second stage cyclones the non-porous and wear proof material, for example concrete, is used.
