An official with the Pars Oil and Gas Company (POGC), Mohammad Mehdi
Tavasolipoor, said the project has made over 30% progress over the course of the
past 6 months ever since it was labeled as a prioritized project at POGC.
He said all the items required for completion of the project have been
ordered, adding a renowned foreign manufacturer is providing the project's heat
recovery steam generators (HRSG) and other parts are being supplied by domestic
In electric power generation, a combined cycle is an assembly of heat
engines that work in tandem with the same source of heat, converting it into
mechanical energy, which in turn usually drives electrical generators.
The principle is that after completing its cycle (in the first
engine), the temperature of the working fluid engine is still high enough that
a second subsequent heat engine may extract energy from the waste heat that the
first engine produced.
By combining these multiple streams of work upon a single mechanical
shaft turning an electric generator, the overall net efficiency of the system
may be increased by 50–60%. That is, from an overall efficiency of say 34% (in
a single cycle) to possibly an overall efficiency of 62.22% (in a mechanical combination
of two cycles) in net Carnot thermodynamic efficiency.
