The operating mode of a gas turbine depends not only upon the intake air parameters but also upon a degree of regeneration. The paper analyses the effect of a regeneration degree on the operation of a considered GT 750-6 gas turbine using a special software developed for this purpose. Based on case calculations, the effect of a degree of regeneration on the specific power and thernal efficiency of the actual GT 750-6 gas turbine is quantified. and Obsahuje seznam literatury
