Biomass gasification is a promising technology for converting organic materials into valuable gases such as syngas, hydrogen, methane, and chemical feedstocks. This process involves complex thermochemical reactions influenced by various parameters. This article explores key factors affecting product quality during biomass gasification, including feedstock composition, moisture content, particle size, operating conditions, catalysts, and sorbent-to-biomass ratio. The study sheds light on the advantages and disadvantages of different gasifier types, such as updraught, downdraught, fluidised bed, and entrained flow, highlighting their suitability for specific applications. It also delves into the significance of parameters like steam-to-biomass ratio and air equivalence ratio. The findings underscore the importance of optimizing these factors to enhance gasification efficiency and minimize undesired byproducts. Biomass gasification holds significant potential for sustainable energy production and should be explored further to harness its benefits effectively. Keywords: Biomass, alternative source of energy, bioenergy, biofuel, biomass gasification, gasifier types.

“…In recent years, gasification reached a considerable level of technical development and emerged as a great alternative due to its high conversion efficiency and versatility. Many studies have proved the superiority of gasification over other biomass conversion processes [4,6,7], and its main product is called producer gas or synthesis gas (syngas). The name producer gas is normally given when the gasification agent is air and has a low heating value, while the name syngas is normally given after purifying the fuel fraction of the producer gas or when the gasification produces a gas with a high calorific value [8].…”

The gasification of residues into syngas offers a versatile gaseous fuel that can be used to produce heat and power in various applications. However, the application of syngas in engines presents several challenges due to the changes in its composition. Such variations can significantly alter the optimal operational conditions of the engines that are fueled with syngas, resulting in combustion instability, high engine variability, and misfires. In this context, this work presents an experimental investigation conducted on a port-fuel injection spark-ignition optical research engine using three different syngas mixtures, with a particular focus on the effects of CO/H2 and diluent ratios. A comparative analysis is made against methane, considered as the baseline fuel. The in-cylinder pressure and related parameters are examined as indicators of combustion behavior. Additionally, 2D cycle-resolved digital visualization is employed to trace flame front propagation. Custom image processing techniques are applied to estimate flame speed, displacement, and morphological parameters. The engine runs at a constant speed (900 rpm) and with full throttle like stationary engine applications. The excess air–fuel ratios vary from 1.0 to 1.4 by adjusting the injection time and the spark timing according to the maximum brake torque of the baseline fuel. A thermodynamic analysis revealed notable trends in in-cylinder pressure traces, indicative of differences in combustion evolution and peak pressures among the syngas mixtures and methane. Moreover, the study quantified parameters such as the mass fraction burned, combustion stability (COVIMEP), and fuel conversion efficiency. The analysis provided insights into flame morphology, propagation speed, and distortion under varying conditions, shedding light on the influence of fuel composition and air dilution. Overall, the results contribute to advancing the understanding of syngas combustion behavior in SI engines and hold implications for optimizing engine performance and developing numerical models.

“…Making the producer gas relatively tar-free allows it to be used directly in an engine generator system to produce electricity and heat. Thus, if producer gas is intended to be utilized directly in an internal combustion engine (ICE), the most significant problem is the tar content of the producer gas 7 , 8 . In rural off-grid areas where ICE is to be used, power generation demands the operation of a downdraft gasifier in order to generate producer gas characterized by a low-tar content, especially for downdraft throatless gasifiers, which is preferably a downdraft batch gasifier for producer gas generation for power applications 9 , 10 .…”

Biomass gasification has significantly advanced in terms of performance and is increasingly used in rural off-grid electricity applications. The downdraft gasifier is primarily used in biomass gasification applications, in which it functions as a reactor into which biomass and gasifying air are introduced to generate producer gas that is then used in an engine generator to produce electricity. However, the safety and stability of biomass gasification remain challenging and depend on several factors, such as the startup heating process, which can affect risks of fire, explosion, and toxic gas emissions. As the biomass gasification is associated with high temperatures and demands safety measures, its startup process should follow a rigorous procedure that ensures reliable operation and minimizes the risk of hazard issues. This study presents a gasifier startup heating process based on a proposed safety protocols hazard analysis. The study indicates that the heating temperature in startup processes has been identified as a critical factor due to its role in impacting safety. The findings indicate that the biomass gasification process has significant risks, including the potential for fire, explosion, and release of environmental emissions via multiple pathways. The methods proposed here could lead to reduced risk from the abovementioned issues.
