Abstract
Traditional bamboo rice production generates substantial biomass residues that frequently remain underutilized, posing significant environmental challenges within community-based production systems. To address this, the current study integrates Computational Fluid Dynamics (CFD) simulations with experimental validation to develop a tailored fuel gas production technology utilizing bamboo-derived charcoal. The research evaluates thermo-fluid characteristics and syngas composition while assessing economic feasibility relative to liquefied petroleum gas (LPG). Findings demonstrate a peak combustion temperature of 706°C, with gas delivery temperatures stabilized between 250–300°C along distribution ducts. Technical analysis reveals a maximum gas velocity of 34.22 m/s in narrow sections, optimizing the flow of syngas comprising 15.14% hydrogen, 25% carbon monoxide, and 2.31% methane. From an economic perspective, bamboo-derived gas provides a superior cost-benefit profile; while LPG offers higher energy density, the waste-derived alternative reduces energy expenses by approximately two-thirds, costing 1.1 THB/kWh compared to 3.9 THB/kWh for LPG. These results confirm that transforming bamboo residues into renewable energy is technically viable and economically advantageous for community-scale thermal applications. By fostering a circular economy and enhancing energy self-reliance, this technology provides a sustainable framework for localized waste management and the transition toward clean energy in community enterprises.
