This work explores the economic viability of a pyrolysis plant processing biochar-based slurry fuel (CS) from rice straw (RS) at production rates of 10 and 40 tonnes/h. Minimum selling prices for 40 wt% biochar in water (CS-W100) and ethanol (CS-E100) slurries were A$ 0.07 and A$ 0.052 per MJ, respectively. The most cost-effective scenario involves processing 40 tonnes/h of feedstock, yielding CS-E100 at A$ 1434.30 per tonne (or A$ 0.052/MJ). A sensitivity analysis highlights the selling price as a pivotal factor, with increased CS-E100 prices to A$ 1476.04 and A$ 1566.63/tonne resulting in profitable scenarios with payback periods of 14 and 8 years and internal rates of return of 14 % and 22 %, respectively. Monte Carlo analysis indicates a 74.73 % and 98.79 % probability of positive net present value (A$ 44.44 million and A$ 140.90 million) at the mentioned selling prices. The study introduces a pioneering hybrid simulation, combining literature and experimental data, to transform waste-to-energy materials into affordable and clean energy solutions through novel slurry fuels.

生物炭浆料燃料厂的技术经济评估 (TEA) 和敏感性分析

这项工作探讨了热解厂以 10 吨/小时和 40 吨/小时的生产率从稻草 (RS) 中加工生物炭基浆料燃料 (CS) 的经济可行性。 40 wt% 生物炭水浆 (CS-W100) 和乙醇浆液 (CS-E100) 的最低售价分别为每 MJ 0.07 澳元和 0.052 澳元。最具成本效益的方案是处理 40 吨/小时的原料，以每吨 1434.30 澳元（或 0.052 澳元/MJ）的价格生产 CS-E100。敏感性分析强调销售价格是一个关键因素，CS-E100 价格上涨至 1476.04 澳元和 1566.63 澳元/吨，导致盈利情景，投资回收期分别为 14 年和 8 年，内部收益率分别为 14% 和 22 年％， 分别。蒙特卡洛分析表明，在上述售价下，净现值为正值（4,444 万澳元和 1.409 亿澳元）的概率分别为 74.73% 和 98.79%。该研究引入了开创性的混合模拟，结合文献和实验数据，通过新型浆料燃料将废物能源材料转化为负担得起的清洁能源解决方案。
