Due to environmental issues, disposing of household garbage is a significant obstacle for life on Earth. Due to this, several sorts of research on biomass conversion into useable fuel technologies are carried out. Among the most popular and effective technologies is the gasification process, which transforms trash into a synthetic gas that can be used in industry. Several mathematical models have been put out to mimic gasification; however, they often fall short of accurately investigating and fixing flaws in the model's waste gasification. The current study used EES software to estimate the equilibrium of Tabriz City's waste gasification using corrective coefficients. The output of this model demonstrates that raising the temperature of the gasifier outlet, waste moisture, and equivalence ratio decreases the calorific value of the synthesis gas generated. Moreover, when using the current model at 800 °C, the synthesis gas has a calorific value of 1.9 MJm3. By comparing these findings to those of previous studies, it was shown that the biomass's chemical composition and moisture content, numerical or experimental methods, gasification temperature, and preheating of the gas input air all had a major influence on process outcomes. The C of the system and the η are equivalent to 28.31 $/GJ and 17.98%, respectively, according to the integration and multi-objective findings.
由于环境问题，处理生活垃圾是地球上生命的一个重大障碍。因此，人们开展了多种将生物质转化为可用燃料技术的研究。其中最受欢迎和有效的技术之一是气化过程，它将垃圾转化为可用于工业的合成气。已经提出了几种数学模型来模拟气化过程；然而，它们往往无法准确地研究和修正模型在气化方面的缺陷。本研究使用 EES 软件通过校正系数来估算 Tabriz 市垃圾气化的平衡。该模型的输出表明，提高气化炉出口温度、废物水分和当量比会降低生成的合成气的热值。此外，当在 800°C 使用当前模型时，合成气的热值为 1.9 MJm3。通过将这些发现与先前研究的结果进行比较，表明生物质的化学成分和水分含量、数值或实验方法、气化温度以及输入气体的预热都对工艺结果有重大影响。根据集成和多目标的结果，系统的 C 和 η 分别等于 28.31 美元/GJ 和 17.98%。
