THERMAL EFFICIENCY IMPROVEMENT FOR A HYDROGEN -AIR FIRED REGENERATIVE MICRO GAS TURBINE CYCLE
Potential application of high temperature of air-combustors has been described in a number of publications. This is because of its environmental advantages as well as its expected performance This paper is a continuation to our previous work 1 aiming at improving the performance of a micro-gas turbine unit. The work was originally carried out by a group of researchers of Tohoku University in Japan 2. Indeed we found out some improvement in the cycle thermal efficiency of the cycle under the same operation conditions. The cycle thermal efficiency was further improved by increasing turbine pressure ratio by introducing a steam condenser into the cycle. Proper selection of combustor and regenerator materials -ceramic in particular- to withstand higher temperature values and attain better regenerator effectiveness as well, improves the cycle efficiency On the other hand, better selection of turbine materials, should improve the cycle efficiency due to internal efficiency increase.
