Chapter 2 Small-scale power plants A typical energy balance of a biomass fired ORC plant is instead shown in Figure 2.25: as one can see, electrical efficiency is about 15%, but the recovery of the condensation heat allows to reach a very high thermal efficiency, about 75%. As a result, first law efficiency can achieve even 90%11. Figure 2.25 – Typical energy balance of a biomass-fired ORC plant [2.18]. As one can see, electrical efficiency is significantly lower than the one reached by internal combustion engines and gas turbines, even considering penalisation due to the fact that it is an external combustion plant. Indeed, this parameter is variable adjusting the condensation temperature. In fact, the case described above refers to the typical configuration in which the organic fluid condensates at 90°C, thus allowing the production of hot water for heating purposes, but it can be lowered down to 40 ÷ 50°C: in this case electrical efficiency raises to about 20%, but it is clear that useful heat recovery is no more possible (neglecting contribution of flue gases). This is why the CHP configuration is normally preferred. Concerning the thermodynamic cycle, given the low-temperature heat source, a superheated approach like in traditional Rankine cycles is not appropriate. Actually, a little superheating is always performed in order to prevent formation of liquid droplets at the intake of the turbine, that would damage the component, but it generally does not 11 These values are quite standardised among the various commercial solutions (that indeed are not numerous yet). 83PDF 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
