Wooden and agricultural biomass combustion in presence of enriched hydrogen gas

What is it about?

This paper introduces a viable and economical solution for reducing the impact of fossil fuels combustion on the environment. The new proposed energy vector solid biomass-hydrogen combines the positive effect of biomass on the carbon emissions and the ones of hydrogen clean gas. The researches regarding hydrogen diffusion (pure or mixed) within biomass are part of a wider research conducted by the authors on utilization of hydrogen as active environment for combustion of solid biomass. The researches focus on the development of an innovative efficient technology for co-combustion of solid biomass with hydrogen enriched gas (HRG).

Why is it important?

By injecting HRG in the primary air in the co-combustion process of biomass, the flame temperature increased by 10%, the CO concentration decreased by 60–80% for specific ratio 15 L/kg, and the combustion efficiency raised by 2–4%. The results reveal the reduction by 40% of SO2 concentration, while the NOx concentration increased by 10%.
