| Abstract | ||
| 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 and water spray system in the inlet air duct of the GT-85-2-H gas turbine. The influence of regeneration and water injection in the air intake 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%. Water injection strongly affects the power output. Water injection tends to increase the brake power output by about 47%.The thermal efficiency is also increased by about 30%.The specific fuel consumption is reduced by about 29%. | ||
