生物质成型燃料(BMF)作为一项相对成熟的技术,在我国分布式和集中供热中得到广泛应用,并受到政府的高度重视。尽管已经制定了许多BFM激励政策,但中国国内传统燃料价格的下降导致BMF失去了经济活力,需要新的政策建议来刺激该行业。本研究基于真实生产过程模拟构建了区域化净现值(NPV)模型来检验各政策因素的影响。计算结果显示,不同地区的BMF生产成本差异很大,农业型煤燃料(ABF)的成本在86美元/吨(USD/t)至110美元/吨(USD/t)之间,而木质颗粒燃料(WPF)的成本在122美元/吨至154美元/吨之间。 BMF成本构成中最大的部分是原料,占总成本的50%~60%;因此原料补贴是最有效的政策因素,但从政策执行的角度考虑,最好还是采用生产补贴。对于ABF,中国不同地区的最佳产品补贴范围为26美元/吨至57美元/吨,而对于WPF,最佳产品补贴范围为36美元/吨至75美元/吨。基于这些数据,本研究还提出了区域BMF发展战略。
As a relatively mature technology, biomass molded fuel (BMF) is widely used in distributed and centralized heating in China and has received considerable government attention. Although many BFM incentive policies have been developed, decreased domestic traditional fuel prices in China have caused BMF to lose its economic viability and new policy recommendations are needed to stimulate this industry. The present study built a regionalized net present value (NPV) model based on real production process simulation to test the impacts of each policy factor. The calculations showed that BMF production costs vary remarkably between regions, with the cost of agricultural briquette fuel (ABF) ranging from 86 US dollar per metric ton (USD/t) to 110 (USD/t), while that of woody pellet fuel (WPF) varies from 122 USD/t to 154 USD/t. The largest part of BMF’s cost composition is feedstock, which accounts for up 50%–60% of the total; accordingly a feedstock subsidy is the most effective policy factor, but in consideration of policy implementation, it would be better to use a production subsidy. For ABF, the optimal product subsidy varies from 26 USD/t to 57 USD/t among different regions of China, while for WPF, the range is 36 USD/t to 75 USD/t. Based on the data, a regional BMF development strategy is also proposed in this study.
