Title:
中間冷却復熱式ガスタービン及び冷媒複合ボトミングサイクルの複合化システム
Document Type and Number:
Japanese Patent JP7241794
Kind Code:
B2
Abstract:
The invention discloses a new type of combined cycle to compete with the standard gas-steam combined cycle in terms of full load/part load efficiency besides ramp rate, startup time and other off design performance. The topping cycle is intercooled recuperative gas turbine (ICR GT) with multiple intercoolers. The bottoming compound cycles consists of supercritical refrigerant Rankine cycle (RRC) and vapor compression refrigeration cycle (VCRC). The refrigerant can be chosen from various organic and inorganic working fluids. The topping and bottoming cycles are highly coupled and form a new integrated cycle rising to the challenge of incoming renewable energy era when thermal power plants undergo frequent load change and long-term part load operation. This invention also markedly outperforms single intercooler ICR GT bottomed by single pressure subcritical RRC system in terms of efficiency, ramp rate etc., and could be an incredibly competitive solution for stationary power generation and marine propulsion.
