Abstract: A modified gas turbine system is provided that adapts an advanced pressurized fluidized bed combustor cycle for use with existing combustion turbine technology. To accommodate current combustion turbine technology, the air extracted from the compressor discharge is limited, e.g. to about 20% of the total. The additional air required for the APFBC cycle is provided by an auxiliary source of compressed air. The compressor discharge air that is not extracted is used for combustion of the fuel gas produced by the carbonizer and also provides internal cooling as required by conventional combustion turbine design. A separate expander turbine is used to recover energy from the vitiated air from the PFBC. Energy from the vitiated air may further be recovered by directing the expander exhaust to an HRSG.

Abstract: An external fluid in a closed loop is used to cool hot gas path components of gas turbine. After cooling the turbine components, the heated external fluid is dumped either in the compressor discharge casing or in the one of the turbine's stages. Where the external fluid is nitrogen to be dumped in the turbine compressor's discharge casing, the nitrogen is compressed using diluent nitrogen compressors. Alternatively, where the external fluid is nitrogen to be dumped in one of the stages of the turbine, the nitrogen is not compressed at all. The turbine blade heat exchangers in the turbine stages through which the nitrogen passes can be connected in parallel or in series for cooling the hot gas path components in the turbine stages. The nitrogen can optionally be mixed with air or steam or not mixed at all.

Abstract: A system and method for recovering heat from dirty gaseous fuel (syngas), wherein the pressure of clean fuel gas is elevated to a pressure higher than that of the dirty syngas and then the pressurized clean fuel gas is fed to a heat recovery unit for heat exchange with the dirty syngas. Consequently, in the event of a leak in the heat recovery unit, the flow is from the clean fuel side to the dirty syngas side, thereby avoiding the possibility of contamination of the clean fuel gas.

Abstract: A gas turbine system that includes a compressor, a turbine component and a load, wherein fuel and compressor discharge bleed air are supplied to a combustor and gaseous products of combustion are introduced into the turbine component and subsequently exhausted to atmosphere. A compressor discharge bleed air circuit removes bleed air from the compressor and supplies one portion of the bleed air to the combustor and another portion of the compressor discharge bleed air to an exhaust stack of the turbine component in a single cycle system, or to a heat recovery steam generator in a combined cycle system. In both systems, the bleed air diverted from the combustor may be expanded in an air expander to reduce pressure upstream of the exhaust stack or heat recovery steam generator.
