Process and device for cleaning exhaust gases For efficient generation of electrical power, de-dusted hot gas (10) is led to a gas turbine. Dustladen hot gas (1) is generated by a pressurized fluidizedbed firing system or by coal gasification at a temperature of 850.degree.C and a pressure of 16 bar and then cleaned in a de-dusting plant (4, 8, 9). The dedusting plant comprises a coagulator (4) for mutual deposition of dust particles and 2 downstream cyclones (8, 9) for separating the dust (13, 14). The coagulator (4) has a bundle of coagulator tubes (5) with attached vibrators (6). A 1st cyclone (8) is fitted with a cyclone electrode (11) for more effective dust separation. Granular bed filters or devices for chemical injection can be provided before, in, or after the coagulator (4) in order to reduce greenhouse gases and/or corrosive gases. (Fig. 2) |
