The equations used in the physical simulation model of the gasifier are primarily stoichiometric calculations of how the biomass is converted through partial combustion. This will calculate adiabatic temperature and cooling through heat transfer and through transport of material from the gasifier and the heat exchangers in the exhaust gas train. The mass in the bed inventory by time is given from: inventory i,in i,out m / t = m - m where mi ,in is the mass input flow of each single component of the composition vector i= (C, H, O, N, CO2, H2O, NO2, ash) and mi, out is the corresponding output flow. The change in concentration of each component is given by ci in the bed inventory: where j are all incoming flows and k all out-going flows of the inventories. Except the bed inventory we also have one inventory for the steam system, gas cooling, filter and scrubber. The steam system has only water and steam components, while the others have the same components as t...
