Performance improvement of a coal gasification and combined cogeneration plant by multi-pressure steam generation

Introducing multi-pressure steam generation in the heat recovery steam generator of a combined power plant is found to improve the performance of the plant than that of the corresponding single-pressure system. Similar introduction of multi-pressure steam process in a coal gasification combined cogeneration plant has been discussed in this paper. The effects of number of different pressures of steam generation and their magnitudes have been estimated by an energy analysis.
