ABSTRACT:
An effective and economical supply of energy from residual oil for power generation can be obtained by a sequential process of partial combustion of a crude or residual oil such as Bunker C and other high sulfur stocks, in the presence of air and steam in a fluidized bed of inert particles followed by a fluidized bed heat exchange for the production of steam and control of solids build-up, the solids-free gas being desulfurized by commerical processes and thence being available for combustion for gas turbine operation to produce transportable electrical power or other types of mechanical power such as a compressor driver. Emission levels of contaminants are within forseeable requirements and turbine maintenance problems are reduced. Coal solids can be used as a supplement to the residual oil. Alternatively, the low BTU gas can be effectively added to pipeline gas as a supplementary source of energy when dilution of high-Btu gas is permitted or used directly as a low-Btu desulfurized industrial fuel.
