Industrial cogenerative application of the HAT cycle with partial humidification by tubular humidifiers. Numerical code for the energy-exergy analysis

摘要

In this the use of the HAT cycle in cogenerative configuration is investigated. Cogenerationis obtained by the utilization of both the heat of gas turbine exhaust gases and the heat of pressurized water resulting from the second body of a twin-body tubular evaporator, both used for process steam production by two heat recovery steam generators. A numerical code is developed to achieve the energy and exergy analysis for many configurations of the HAT 1 cycle, in order to evaluate the thermodynamic suitability and engineering. In detail, the code allows to correlate power and output of plants-by three main parameters, i.e. the gas turbine partial compression ratio of the two stage compressor and the fractional flowrates of both the compressed air and the exhaust gases utilized for humidlfication.
