“…In contrast, the second-generation biofuels can be produced from alternative lignocellulosic materials, such as wood, vegetable waste and nonedible plants, offering an even more favorable well-towheel CO 2 balance without negative impact on food supply [16][17][18][19][20].…”

“…Laboratory research carried out by one of the authors through the small-scale prototype of the pulverized burner system (called BRENDA) reveal that the particle size has large influence to the flame structure: the finer the biomass is the better and longer the flame length. Research and industry applications conclude that pulverized biomass systems typically reduce emissions of greenhouse gases and sulphates [18,19].…”

“…Biomass, as a solid fuel, could be used in various sizes and shapes; powder biomass has been recognized as the most attractive form since it burns like gases-fuels [19][20][21][22]. Nevertheless, powder biomass combustion is complicated; it comprises overlapping numerous processes, such as drying, gasification/devolatilization, and char formation and oxidation [23]. Among different processes, the gasification and/or devolatilization process is recorded as one of utmost significance and may be one of the most complicated processes [24].…”

Biomass is currently one of the world’s major renewable energy sources. Biomass in a powder form has been recently proposed as the most encouraging of biomass contours, especially because it burns like a gas. In the current study, biomass powder was examined, for the first time, as a direct solid fuel in internal combustion engines. The aim of the current study was to investigate modeling tools for simulation of biomass powder in combustion engines (CE). The biomass powder applied was in a micro-scale size with a typical irregular shape; the powder length was in the range of 75−5800 μm, and the diameter was in the range 30−1380 μm. Different mechanisms for biomass powder drying and devolatilization/gasification were proposed, including different schemes’ and mechanisms’ rate constants. A comparison between the proposed models and experiments was carried out and results showed good matching. Nevertheless, it is important that a biomass powder simulation addresses overlapping/complicated sub-process. During biomass powder combustion, tar was shown to be formed at a rate of 57 wt.%, and, accordingly, the formation and thermal decomposition of tar were modelled in the study, with the results demonstrating that the tar was formed and then disintegrated at temperatures between 700 and 1050 K. Through biomass powder combustion, moisture, tar, and gases were released, mostly from one lateral of particles, which caused ejection of the solid particles. These new phenomena were investigated experimentally and modeled as well. Results also showed that all the proposed models, along with their rate constants, activation energies, and other models’ parameters, were capable of reproducing the mass yields of gases, tar, and char at a wide range of working temperatures. The results showed that the gasification/devolatilization model 3 is somewhat simple and economical in the simulation/computation scheme, however, models 1 and 2 are rather computationally heavy and complicated.
