Gas turbine in a power plant with circulating pressurized fluidized bed combustion

The objective of introducing the circulating variant of pressurized fluidized bed combustion is coupled with the intention to simultaneously implement this technology with standard gas turbines designed for combusting high-grade fuels such as natural gas and distillate fuel oil. This presentation uses the commercially-offered Siemens gas turbines to illustrate the associated requirements imposed on the coal conversion system and hot gas cleanup as well as necessary modifications to the gas turbine. The report focuses both on power plants equipped with conventional circulating pressurized fluidized bed combustion (PCFB 1. Generation) and those with partial coal gasification (PCFB 2. Generation).
