Recent experimental results on gasification and combustion of low Btu gas for gas turbines

Conference ·
OSTI ID:7186328
A proposed system is presented for low pollution power generation by means of a combined cycle gas turbine system using low Btu fuel gas produced from high sulfur residual oil and solid fuel by gasification. Experimental results and conclusions are presented from a cooperative research program where high sulfur crude oil residue was partially oxidized with air to produce a 100 to 150 Btu/scf sulfur-free fuel gas for use in a turbine combustor. An FT4 gas turbine combustion chamber test demonstrated that low Btu gas can be efficiently burned with a large reduction in nitrogen oxide emissions. Gas turbine modifications required to burn low Btu gas are described, and projected NO/sub x/ emissions for the low Btu gas compared to No. 2 fuel oil and natural gas are shown for an FT4 gas turbine. Integration of the gas turbine combined cycle system to a low Btu gasification process is described. The system provides an efficient method of generating electrical power from high sulfur liquid fuels while minimizing emissions of air and water pollutants.
