Show CONCLUSIONS Results from commercial gas turbine plant operations and from large scale combustion trials confirmed that machines equipped with a large volume single combustion chamber, such as the BBC units, can successfully and advantageously be used in the firing of low grade fuels. The range of these fuels include low heating value gases, petroleum crudes, residues, and alternative fuels of the future. The design of the large volume combustor provides sufficient residence time to achieve complete carbon burn-out for low hydrogen fuels and to avoid overheating due to increased luminosity of these flames. Environmental concerns due to adverse fuel properties did not materialize either with the use of the low grade fuels; therefore, it appears to be justified to reach the overall conclusion that the present-day commercial machines described are directly applicable for low grade fuel service and through reduced fuel cost can lessen the cost of power generation.
