Abstract
A process for the efficient production of power from non-gaseous carbonaceous fuels, such as coal, or heavy fuel oil, in a steam power plant in which the carbonaceous fuel is first gasified at relatively high pressure and temperature by partial oxidation with oxygen to produce a fuel gas, the fuel gas from the partial oxidation reaction is expanded to a lower pressure in a turbine. Undesirable compounds, e.g., sulfur compounds, are removed from the fuel gas, and the fuel gas supplied to a steam boiler for the production of power. The process of this invention provides an effective means for conversion of gas-fired steam generation facilities to coal or heavy fuel oil while at the same time increasing the power generating capacity of the installation, all with minimal atmospheric pollution. The process is effective for the conversion of other types of gas-fired heaters and boilers to coal or heavy fuel oil.
