ABSTRACT:
Gas-fluidized ground coal, and coal dust slurried with fuel oil, are supplied to a reverse flow cyclone combustor which provides the functions of combustion and particulate removal. Coal dust borne by the fluidizing gas is passed through a cyclone scrubber utilizing fuel oil, and the resulting slurry is introduced into the combustor adjacent the inner surface of the combustor wall. Only the finest coal dust is employed in the slurry, to minimize oil consumption. Separative performance of the combustor is enhanced by introducing combustion air centrally adjacent the combustor outlet and gas-borne ground coal directly onto the cyclone walls.
