    Patent number: 4210632
    Abstract: A method and apparatus for calcining limestone in which limestone is burned continuously in a vertical kiln provided with at least one fuel injector which permits pulsed introduction of fuel thereto. Combustion air is passed continuously through the kiln and air/fuel mixing efficiency is enhanced by the use of an arch or hood superposed above the fuel injectors to thereby create a protected space in the mass of charged limestone.
