Thermoeconomic optimisation of heat recovery steam generators of combined cycle gas turbine power plants considering off-design operation

Thermo-economic optimization of heat recovery steam generator for a range of gas turbine exhaust temperatures

“…Carapellucci and Giordano [23] undertook a thermo-economic optimization of several types of HRSG adapted to three types of GT, and investigated the effect of fuel price and capacity factor on the electricity cost. Rovira et al [24] considered the frequent off-design operation of CC and developed a thermoeconomic optimization model in order to minimize the electricity cost. Bakhshmand et al [25] have optimized a CC with supplementary firing leading to 3% decrement in the power plant specific cost and consequently the cost of electricity.…”

Optimization of fog inlet air cooling system for combined cycle power plants using genetic algorithm

“…The basic idea was to use the hot flue gasses, available at the end of the expansion stage of the gas turbine in Brayton cycle in order to produce hot and high-pressure steam in the bottoming cycle. Heat recovery steam generator (HRSG) is the place where steam heating takes place [1][2][3][4][5][6]. In order to obtain high thermal efficiencies of combined cycle plants up to 60% by the existing technologies, attention have been focused on the gas turbine cycle, by optimizing its performance improvements, which can be accomplished by several world-know technologies such as gas turbine inlet cooling methods and gas turbine blade cooling technologies.…”

Análisis energético, exergético y económico de un sistema de cogeneración: Caso para una planta azucarera de San Pablo

“…Este término no es nuevo; las plantas industriales han utilizado el concepto de cogeneración a principios de 1880 cuando el vapor era la principal fuente de energía. Sin embargo, en la actualidad este tipo de procesos todavía desempeñan un papel importante en la producción de energía, pues, sus bajos costos de inversión, operación y mantenimiento, así como su mayor eficiencia y menor impacto ambiental los hacen más atractivos [2][3][4].…”
