Abstract
The invention relates to a device for using oxygen for the thermochemical gasification of biomass in at least one fluidized-bed reactor, a heating system being located in the fluidized bed of said reactor and the fluidized-bed reactor being heated by the at least partial oxidation of a combustible gas using oxygen.
Claims11
A fluidised bed reactor for producing synthesis gas by gasification of solid fuels, having a heater for heating a fluidised bed of the fluidised bed reactor, the heater having at least one cavity,
- wherein the heater has an oxygen feed for delivering a gas containing oxygen into the cavity of the heater and the cavity adjoins a porous, gas-permeable section of the heater, and
- wherein the heater is located within the fluidized bed of the reactor and comprises a plurality of tubes arranged concentrically with one another, respectively with an inner tube and an outer tube, at least the inner tube or the outer tube being formed so that it is porous and gas-permeable and the oxygen feed is formed so as to deliver the gas containing oxygen to an annular space between the outer tube and the inner tube.
