THE INFLUENCE OF REGENERATION ON TWO-SHAFT GAS TURBINE PERFORMANCE
A two-shaft gas turbine type GT-85-2-H has been modified and converted into a research unit. The main modifications consist of incorporating regeneration system in GT-85-2-H gas turbine. The influence of regeneration on gas turbine performance has been studied. The results show that regeneration improves the thermal efficiency by about 56 % due to reduction in the fuel consumption, and reduces the power output due to back pressure losses that occur because of the regenerative system by about 20,67 %. The brake specific fuel consumption is reduced by about 59 %.
