For a rational production of electrical energy, a hot dusted gas (10) is sent to a gas turbine. The hot dust-laden gas (1), produced by combustion in a fluidized bed under pressure or by gasification of coal, at a temperature of 850 ° C. and under a pressure of 16 bars, is then purified in a dedusting installation (4, 8, 9). The latter comprises a coagulator (4) for fixing the dust particles to one another and two cyclones connected in series (8, 9) for separating the dust (13, 14). The coagulator (4) has a bundle of tubes (5) fitted with vibrators (6). A first cyclone (8) is equipped with an electrode (11) ensuring a more efficient separation of dust. Packed bed filters or chemical injection devices can be provided upstream, inside or downstream of the coagulator (4), in order to reduce greenhouse gases and / or corrosive gases. |
