Model based optimization of the control strategy of a gasifier coupled with a spark ignition engine in a biomass powered cogeneration system

The plant model is realized by schematizing the whole biomass-to energy chain within the Thermoflex™ environment and, simultaneously, by improving the prediction of the ICE performance through a properly developed and validated one-dimensional (1D) model in GTSuite. Simulation of the combustion process is specifically customized for syngas use, namely to account for the extreme variability of this fuel that strongly depends upon the kind of processed biomass and the gasifier operating conditions. The system model is validated on the ground of experimental data collected in the real plant and is coupled with the modeFRONTIER software for the optimal choice of the main operating parameters.
