2nd European Conference on Polygeneration – 30th March -1st April 2011 – Tarragona, Spain Turbine and alternator The turbine, a modified single stage type (C10S-II) by Tuthill Nadrowski, is expected to work with an isentropic efficiency of 0.78. The unit is connected to a gearbox (ratio 1:6). The nominal speed of the turbine is 500 RPM which is transformed to 3000 RPM for the synchronous alternator. The generator (DGI 450/2L WT) produced by Weier Electric with a rated power of 1500 kVA has the following characteristic: Table 1: Load specifications of alternator [19] The table shows two efficiencies, with and without cooling. In this case the alternator is equipped with a cooler thus the net efficiency values have to be taken. On base of the constant turbine efficiency given by the manufacturer and the alternator characteristic one should expect a degree of efficiency stable over a wide range. To examine the turbine performance the thermodynamic states before and after the turbine have been measured (pressure, temperature). Furthermore the mass flow is taken after the feeding pump. Based on those values the turbine efficiency is calculated. To obtain the thermodynamic properties, formulations based on Peng-Robinson [4] and Colonna et al. [7]/[8] have been used. Figure 5: Isentropic efficiency of turbine versus fluid mass flow Figure 5 shows a plot of turbine efficiencies of one week. The widely scattered points derive from opening and closing of the turbine control valve. These points are not representative for steady-state operation. The main cloud of points shows that the isentropic efficiency of the turbine is not design point. The turbine misses the design efficiency under full load conditions by 5 percentage points under the design specifications. The average value over this week is 5PDF Image | ElectraTherm Green Machine 190 to 240 F

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
