Abstract

Fuels, particularly caking fuels, are supplied in a fluidized bed reactor by conveying a fuel through an injection pipe with an end provided with an injection nozzle in a fluidized bed reactor, conveying a fluid through a jacket pipe surrounding the injection pipe and having an end provided with a jacket nozzle, wherein the jacket pipe is interrupted prior to the jacket nozzle, as considered in the flow direction, and at a predetermined location, and bypassing by a heat exchanger at this location at which the jacket pipe is interrupted.
