Abstract:
1. A device for the gasification of solid fuels such as bituminous coals and cokes such as bituminous or lignite coke, biomass coke, and petroleum coke in the entrained flow with an oxidizing medium containing free oxygen, comprising: a system for preparing and feeding slurry made from slurry fuel with a grain size of <200 μm, water and added surfactant, such that the slurry has a solids concentration of 40-70 wt %; a reactor for the gasification of supplied powdered fuel with an oxidizing medium containing free oxygen, said reactor operating at a pressure between atmospheric pressure and 100 bar and at a temperature between 1200 and 1900° C. and comprising a supply pipe for slurried fuel received from said system and a line for the oxidizing medium, which is fed by burners into a reaction chamber having a cooling shield consisting of water-cooled pipes welded gas-tight and an outlet device; a quenching cooler with no internals, said quenching cooler being connected to the reactor and having nozzles arranged in one or more nozzle rings through which is sprayed water for quenching, said nozzles being flush with an inner jacket; and a gas cleanser comprising a crude gas scrubber and partial condenser, or a device for dry dust separation, connected to the quenching cooler.
