This is not the place for accusations and trash talk. (We can leave that to professional athletes.) Stick to technical discussion of gasification. Ownership of the designs used in this discussion are currently confused and not appropriate for discussion on this forum. The "owners" can report to us only after they have sorted things out amongst themselves offline. That could take months. If the data, like the gas analysis, is not believable show example so of what is. A useful model of gas analysis was published this week by the American Chemical Society: Modified Thermodynamic Equilibrium Model for Biomass Gasification: A Study of the Influence of Operating Conditions Maria Puig-Arnavat, Juan Carlos Bruno and Alberto Coronas Energy Fuels, Article ASAP DOI: 10.1021/ef2019462 Publication Date (Web): February 02, 2012 Copyright C 2012, American Chemical Society http://pubs.acs.org/doi/abs/10.1021/ef2019462 This paper presents a mathematical model for biomass gasification processes developed in the equation solver program Engineering Equation Solver (EES) with an implemented user-friendly interface. It is based on thermodynamic equilibrium calculations and includes some modifications to be adapted to a real process, in which only a partial approach to chemical equilibrium is achieved. The model can be used to predict the producer gas composition, yield, and heating value for a certain biomass with a specific ultimate composition and moisture content. It has been validated with published experimental data from different authors for downdraft, fluidized-bed gasifiers and different biomasses, showing good agreement between reported data and modeled values. In addition, it has been used to evaluate the influence of different operating parameters [equivalence ratio (ER), air preheating, steam injection, and oxygen enrichment] on producer gas. The model predicts the behavior of different kinds of biomass and becomes a useful tool to simulate the biomass gasification process by allowing its integration in complete energy supply systems, such as co-generation plants. _______________________________________________ Gasification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: http://gasifiers.bioenergylists.org/
