    摘要: An integrated gasification combined cycle plant is combined with a Kalina bottoming cycle. High thermal energy streams 31, 69, 169 from the gasification system are provided in heat exchange relation with the two component working fluid mixture at appropriate locations along the Kalina bottoming cycle units to supplement the thermal energy from the gas turbine exhaust 28 which heats the working fluid supplied to the vapor turbines. Particularly, low temperature heat recovery fluid from the low temperature cooling section 50b of the gasification system lies in heat exchange relation 27 with the condensed working fluid from the distillation/condensation sub-system of the Kalina cycle to preheat the working fluid prior to entry into the heat recovery vapor generator 12. Heat recovery fluid from the high temperature gas cooling section 50a of the gasification system is placed in heat exchange relation 23 and 65 with the working fluid at an intermediate location along the heat recovery vapor generator 12. By supplementing the heat of the gas turbine exhaust with available heat from the gasification system, and optimal integration, increased power output and improved efficiency are obtained.

    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: 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.

    摘要: 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.
