This figure shows interesting behaving of the partial cooling, the cycle has similar trend (but not so steep) as the re-compression placed at higher turbine pressure ratios. Both cycles characteristics maximum is almost equal. The pre-compression cycle trend is similar to the simple Brayton cycle, likewise partial cooling is placed at higher turbine pressure ratios. 0,50 0,48 0,46 0,44 0,42 0,40 0,38 0,36 Brayton Recompression Split expansion Partial cooling Precompression 2 2,2 2,4 2,6 2,8 3 3,2 3,4 3,6 3,8 4 Turbine Pressure Ratio [-] Figure 2.4 Results of analysis for turbine inlet pressure 25MPa The re-compression thermal efficiency trend has moved, together with split expansion and partial cooling, to higher turbine pressures ratio and became less steep; furthermore higher value of thermal efficiency is achieved. The pre-compression thermal efficiency has little increase and the characteristic trend is rather flatter. 3 Conclusion From the cycles analysis, has emerged: • Operating close to the critical point is not improving much the simple brayton cycle thermal efficiency. Only for compressor outlet pressure about 25MPa is visible an increase but it falls rapidly with some change in the pressure ratio. • The pre-compression cycle can reach high efficiency for compressor outlet pressure 10MPa (see Figure III.2.2), which mainly depends on the precompressor inlet temperature and ratio of pressures ratio. • The re-compression cycle achieves the highest efficiency for optimal pressure ratio, which corresponds to compressor inlet pressure about 7.7MPa. With a change of this ratio, the efficiency significantly decreases. • The split expansion cycle behaves as the re-compression cycle but reaches lower thermal efficiency due to pressure reduction in the reactor. • Partial cooling cycle reaches higher efficiency for high ratio of pressures ratio, likewise pre-compressor cycle. For increasing compressor outlet pressure are the characteristics moving to higher turbine pressure ratio. • The benefits of partial cooling cycle with improved regeneration higher thermal efficiency, pale in overall cycle complexity, which causes pinch point problems within recuperators.
