Fine grained coal is fed into a first chamber of a generally horizontally extending fluidizing bed reactor while a stream of hot solid heat exchange material is passed through the chamber. The coal is then subjected to a fluidizing action with a low nitrogen and low oxygen content so as to degas the coal particles and obtain the combustible gases and liquid byproducts. The coke particles thus formed are then passed into an adjoining second chamber which acts as the combustion chamber and are subjected therein to fluidization with air and burning. Steam is generated in water-filled conduits passing through said second chamber. The heat exchanger particles are simultaneously heated up and are continuously fed back into the first zone of the reactor to contact fresh coal introduced thereinto.
