Benefits of Hydrogen-Rich Gas (HRG) on Biomass Combustion Performances

Due to accelerated globalization, climate change and the increased costs of classical fuels, the notion of biomass is growing in recent years. Harnessing fuels as well as biofuels or hydrogen-rich gas (HRG) helps in a sustainable and environmentally friendly development of the energy sector. Although biofuels cover a vast field in terms of calorific value, maintaining a certain level of humidity is a real problem in practice. Thus, the primary combustion is difficult, and the combustion plants and their performances are restricted. Ideally, the humidity is recommended to be a maximum of 30%. Hydrogen-rich gas (HRG) is obtained from electrolysis, without the need to separate the two gaseous elements H2 and O2. Stoichiometric combustion is performed with oxygen from the gaseous fuel, the rest at the level of excess air being completed from the oxidizing medium. The experiments are carried out on pilot installations from University Politehnica of Bucharest and the advantages of co-combustion of solid biofuels with hydrogen-rich gas are highlighted. As a result, you want to increase the speed and combustion and decrease the CO emission. The limits of mass participation of avian waste mixed with biomass for co-combustion will be studied, with the highlighting of the influence of humidity and calorific value.
