Pollutant emissions restrictions have driven gas turbine manufacturers to employ new technologies and to operate these systems in extreme operating conditions. These operating conditions produce in some cases combustion instabilities which can have dramatic effects for the turbine. Extended experimental and numerical studies are then required to analyze the possible behavior of the end design.

A reduced-order model (ROM) is considered a promising solution for engineering simulation of a gasifier. In this study a ROM of a commercial-scale opposed multiburner gasifier is developed based on a reactor network model (RNM). The RNM blocking for this gasifier is established and validated based on analysis of the gasifier flow field.
