Integrated gas turbine power generation system and process.

摘要

The system includes a circulating fluidized bed combustor (1) coupled at its outlet (7) to a particle separator (5). A vertical return channel (10) is provided for conveying separated solid particles from the separator (8) back to the combust ion chamber (2). A gas turbine cycle (18) is provided, including a gas compressor (19), a heat transfer means (21) directed to a first duct to the compressor (19) for heating the compressed oxidizing gas, a gas turbine (23) connected through a second duct (22) to the heat transfer means (21) for power generation and a third duct (27) for conveying expanded oxidizing gas from the turbine (23) to the combustion chamber (2). The heat transfer means (21) includes tubes (31) disposed inside the vertical return channel (10) for indirect heat transfer between the compressed gas and the dense suspension of separated particles flowing downwardly in the vertical channel (10).
