ABSTRACT:
Fine particulate solid fuel is utilized in the calcining or uniflow shaft of a uniflow regenerative shaft furnace having outlet openings of fuel lances of the furnace arranged with a uniform distribution over the cross-section of the furnace shaft in a horizontal plane between the preheating zone and the calcining zone of the furnace. The fuel feed is maintained constant with time by a dosing system through which fuel is supplied through feed lines to the fuel lances. Due to the uniform distribution of solid fuel which is accomplished, a calcined material is obtained which has a quality comparable to that which may be achieved through calcining with gaseous or liquid hydrocarbons.
