«A mathematical model of SmartValley for estimation of contribution of biomass to the electrical generation»
Jorge Mírez ; Segundo Horna ; Daniel Carranza
2019 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC). Ixtapa, Mexico, Mexico
Abstract:
A mathematical model is presented for the estimation of the contribution of biomass to the generation of electricity for a valley as a geographical scope of application. Is considered that a valley has several species that are cultivated during the year and that have by-products of the harvest that we have considered as biomass that can be used for the production of electricity that would benefit the valley’s inhabiting community. We have called this integration between population and crops SmartValley, which leads to the use of monitoring, control, management and planning among the different agricultural-energy actors.

J1119e: Products from Thermochemical Biomass Processing….

The basis of a fuel or chemical production system is that the feedstock is converted to a useful primary energy product and either used as such, or further converted, upgraded or refined in subsequent processes to give a higher quality and higher value secondary product as shown in Figure. When organic materials are heated in the absence of air, they degrade to a gas, a liquid, and a solid as summarised in Figure. It is possible to influence the proportions of the main products by controlling the main reaction parameters of temperature, rate of heating, and vapour residence time. For example fast or flash pyrolysis is used to maximise either the gas or liquid products, depending on temperature as summarised below:
  • Slow pyrolysis at low temperatures of around 400°C and long reaction times (which can range from 15 minutes to days in traditional beehive kilns) maximises charcoal yields at about 30% wt.
  • Flash pyrolysis at temperatures of typically 500°C; at very high heating rates and short vapour residence times of typically less than 1 second or 500 ms; maximises liquid yields at up to 85% wt (wet basis) or up to 70% dry basis.
  • Similar flash pyrolysis at relatively high temperatures of above 700°C; at very high heating rates and similarly short residence times maximises gas yields at up to 80% wt. with minimum liquid and char production.
  • «Conventional» pyrolysis at moderate temperatures of less than about 500°C and low heating rates (with vapour residence times of 0.5 to 5 minutes) gives approximately equal proportions of gas liquid and solid products

J1118e: Thermochemical Conversion Technologles and Products…

abril 12, 2020 in Bioenergía, Bioenergy, Biomasa, Biomass

There are four thermochemical methods of converting biomass: pyrolysis, gasification, liquefaction and direct combustion. Each gives a different range of products and employs different equipment configurations operating in different modes. These are summarised below in figure
