ThenThe invention relates to a method for cooling raw gases of fluidized bed gasificationnsolid fuels under pressure, the hot, particle-laden raw gases,nthe fluidized bed gasifier with the carburetor outlet temperaturenleave, with water vapor and / or carbon dioxide containing second gasification agentsnbe cooled by endothermic reaction.nAccording to the inventionnProcedure so led thatnin the hot,nParticles laden raw gases, the fluidized bed gasifier with thenLeave carburetor outlet temperature, so steam and / ornCarbon dioxide are mixed in that by endothermic reactionnwith the overheated onesncarbonaceous particles of the raw gases as a result of interferencenformed reaction gases up to their final kinetic reaction temperaturenor cooled below itnbe so that the particle-laden raw gases are no longer for high-temperature pollution, buildupnor corrosion. |
