A gas feed element is provided. In the gas feed element for feeding gas into a dust-like loose material having a high permissible differential pressure in respect of the thickness of the gas feed element and a high operating temperature range, a support plate having openings (holes) is arranged on the side of the filter material facing the gas flow and on the side of the filter material facing away from the gas flow. The gas feed element permits rapid pressurization of a pressure vessel containing a stock of coal dust. Particular configurations of the filter material are provided by metallic filtration mesh with or without support mesh, sintered metal and sintered polymer, in each case having a filter fineness of from 5 mum to 1000 mum. |
