Chapter 2 Small-scale power plants First of all, one can see that the maximum cycle temperature is no more the turbine inlet temperature, TIT, but COT, standing for Combustor Outlet Temperature. In fact in IFGTs they coincide (at least on first approximation) and one usually refers to TIT; on the contrary, in EFGTs these values are different due to the plant architecture and therefore COT must be used. However, the curves progress is similar to the previous case: as indeed predictable, efficiency reaches a maximum here, too and then decreases with increasing pressure ratio, even if maximum values are detected in a smaller range of pressure ratios (3 ÷ 4.5 against 3 ÷ 5.5); on the other hand, values are significantly lower: in particular differences in the maximum efficiencies are about 7 ÷ 9% in absolute terms, that is 30 ÷ 40% in relative terms. As obvious, this is mainly due to the different role of the heat exchanger and in fact TIT, that is the real main operative parameter, is now considerably lower than the corresponding COT: indeed with ε = 100%, COT and TIT would be equal and the efficiencies themselves would also be almost equal. Of course there would be several other factors (even conflicting, e.g. the stream flowing through the turbine in EFGTs has lower mass flow rate and specific heat capacity in respect to the IFGT case, but fuel compressor consumptions are also lower, etc.), but they are of minor importance. Finally, the incidence of the heat exchanger effectiveness on EFGTs electrical efficiency is shown in Figure 2.22 (in this case COT is fixed at 950°C). 28 26 24 22 20 18 16 14 EFGT - Electrical efficiency vs β - ε 1 2 3 4 5 6 7 8 9 10 11 Pressure ratio ε = 90% ε = 88% ε = 86% ε = 84% ε = 82% ε = 80% Figure 2.22 – Effects of the heat exchanger effectiveness on EFGT electrical efficiency. 79 Electrical efficiency [%]PDF Image | SMALL-SCALE BIOMASS POWER GENERATION

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
