Chapter 3 Working hypotheses and preliminary analysis The main input to define the gasifier are: • type of oxidiser (air or oxygen: being small-scale plants, air is always being used; as one can see, water/steam can in case be fed another way); • type of input specification by the user: air flow ratio or gasifier temperature, obviously with the respective datum (the latter was chosen in this work, letting then system fix the proper mass flow rate); • gasifier pressure. Other minor parameters then complete the model: auxiliaries power consumption, slag exit temperature, etc., while biomass type has previously been defined. Syngas composition (in volumetric terms) and lower heating value as well as, given the mass flow rates, cold gas efficiency of the gasifier are the provided results. 3.3.1 Reliability of the model As specified in the Introduction, the first operation is aimed at verifying reliability of the gasifier model supplied by ThermoflexTM. Indeed, complete modelling of biomass gasification is not a purpose of this work, but is just one of the addressed issues, therefore it is sufficient here to verify that results provided by the software are in line with those found of literature or commercial plants, without discussing them too much in detail. In particular this verification has been carried out considering two different references. The first one is a computational code, designed for simulation of biomass gasification, available on the website of Savona Combustion Laboratory, Dipartimento di Macchine, Sistemi Energetici e Trasporti (DIMSET/SCL), University of Genoa [3.2]. It is a simple executable program, analogous to the ThermoflexTM model in terms of required inputs and provided outputs. It is quite obvious that the two models have been fed with the same wood type (weight composition: C – 50%, O – 44%, H – 6%, i.e. CH1.44O0.66 in molar terms; moisture: 10%) in the comparison analysis, varying gasification temperature in the range 500 ÷ 1200°C at ambient pressure and using air as oxidiser: results denote very good correspondence, as shown in Figures 3.4 ÷ 3.6 (the evolution of CO and H2 content and of air/fuel ratio is presented for summary purposes, only). 98PDF 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
