Direct use of biomass powder in internal combustion engines

Abstract

A first general assessment of the biomass dust-fuelled engine concept by testing four biomass powders in a single-cylinder engine.

Controlling HCCI ignition timing of biogas by direct injection of solid biomass

“…This technology of implementing solid and liquid fuel into the combustion chamber represents most studies in the literature related to solid fuel dust in an internal combustion engine. Recent developments of coal slurry engines have adopted several technical advancements while improving slurry development and injection for higher concentrated slurries (60-65% coal) [ 35]. Some of these developments considered using dry biomass powder in engines instead of coal [33] [35].…”

“…The ignition timing control can be assured by both the injection timing and the ignition properties of the injected particles. Most studies in the literature as described above, are limited to the solid particle's combustion in a hot gaseous mixture, and very few consider the interaction of particles with the reactive gas mixture [35]. Based on a gaseous reactive mixture, the quasi-homogeneous species concentration will provide the optimal conditions for the non-production of soot.…”

“…Using solid biomass as a fuel in an internal combustion engine (ICE) could be of great interest because it could combine the ICE's versatility with the large availability and the CO2-neutral impact of biomass fuels [14,33]. Only a few existing programs consider using dry biomass powder in internal combustion engines [34], [35]. However, for these studies, the particles were fueled directly or indirectly to the combustion chamber and not with a controlled injection system.…”

Biofuels and Nanocatalysts: Python Boosting Visualization of Similarities

“…Biofuel is any material used to generate energy from biomass [ 1 ]. Biofuels’ energy source comes from biomass, which stores the sun’s energy as chemical energy [ 2 ].…”

Fine comminution of torrefied wheat straw for energy applications: properties of the powder and energy balances of the production route

“…5 The energy released can be recovered as a mechanical force and used for high-power generation. Previous studies by our team 4,[6][7][8] have demonstrated that an ultrane lignocellulosic powder, with a median particle size of around 20 mm, is fully compatible with this application 7 but the energy released depends on the physical and chemical properties of the powder. Thus, the production of such powdered fuel is entirely green, provided that the energy required for the milling remains lower than the heating values of the lignocellulosic biomass.…”
