  • Method for producing a dried particulate coal fuel from a particulate low rank coal
    Patent number: 4501551
    Abstract: A method for producing a dried particulate coal fuel having a reduced tendency to spontaneously ignite from a low rank coal by drying the low rank coal in a fluidized bed, cooling the resulting dried coal in a fluidized bed cooler, separating coal particles smaller than about 80 Tyler Mesh from the cooled dried coal and treating the cooled dried coal with a deactivating fluid.
    Type: Grant

    Inventors: Louis P. Riess, Bernard F. Bonnecaze
  • Process for cooling particulate coal
    Patent number: 4401436
    Abstract: In a process for drying particulate coal by passing a heated gas through the particulate coal in a heating zone and thereafter cooling the dried particulate coal in a cooling zone, an improvement comprising the addition of a controlled quantity of water to the dried coal in the cooling zone so that the coal is cooled by evaporation of the water.

  • Method for producing a dried coal fuel having a reduced tendency to spontaneously ignite from a low rank coal
    Patent number: 4396394
    Abstract: A method for producing a dried coal fuel having a reduced tendency to spontaneously ignite from a low rank coal by drying the low rank coal and thereafter cooling the dried coal to a temperature below about 100.degree. F. Optionally the dried coal is partially oxidized prior to cooling, and optionally the dried coal is mixed with a deactivating fluid.
