The internal heat recirculation from the porous matrix hosting the flame zone enhances burner Indoximod and offers outstanding fuel interchangeability capabilities. This is of major importance especially for the case of low calorific value fuels, where there are studies examining the performance of porous media combustors under such operation conditions [23] and [24]. Moreover, the porous burner technology provides a particularly attractive combustor for fuels presenting large variation in their constituent composition. Such fuels, as for instance synthesis gases from gasification plants, exhibit as a result diverge combustion characteristics such as burning velocities, ignition time delays and flammability limits [25]. Porous inert medium and packed bed burners have been also proven to operate satisfactory, as far as pollutant levels and combustion efficiency are concerned, for CO2-rich fuels, such as biogas mixtures, which are increasingly penetrating modern applications [26] and [27]. In addition, there is a fostered request on burning hydrogen-enriched fuels. The last years there is an increasingly shifting interest from applying porous media technology for hydrogen and synthesis gas mixtures reforming [28] and [29] to burning such blends as well [30], [31] and [32]. In PGAL (phosphoglyceraldehyde) regard, the present study focuses on characterizing a porous media burner while operating in typical mixtures which involve the latter streams and resemble natural gas, biogas and synthesis gas blends in near equimolar ratios.
