摘要： 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.

摘要： Low grade heat recovered from various sections of an integrated gasification system is used to drive an absorption chilling cycle. In an exemplary embodiment, the recovered low grade heat is used to heat a two component working solution that is pumped through a closed cycle absorption chilling system. The heated working solution is separated into a rich stream and a lean stream. The rich stream is condensed to produce a liquid rich stream that is throttled to reduce its temperature and then evaporated to produce a cooling load. The cooling load may be used for auxiliary cooling needs in the integrated gasification system. The rich vapor stream produced by the evaporating step is mixed with the lean stream to produce a mixed stream, which is cooled in an absorber to produce the working solution for the cycle to be repeated.

摘要： 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.
