摘要：气流床气化是生物质大规模高效转化利用的选择之一。本文首先对生物质气流床气化工艺涉及到的制粉、输送、气化等关键单元进行分析,论证了气流床技术应用于生物质气化的可行性;在此基础上,选用6种典型的农林生物质作为原料,借助Aspen Plus化工流程模拟软件开展生物质气流床气化模拟,研究了煤和生物质共气化及生物质单独气化特性,并对以生物质为原料的气化过程进行减碳效应分析。结果表明:生物质气流床气化具备操作可行性;在煤中掺混适量的生物质既能维持较好的气化性能,又能显著降低煤耗等指标,减碳效果明显;与传统的固定床和流化床相比,生物质气流床气化获得的合成气热值约为10 MJ/m^(3),优势明显,可用于替代天然气供暖,既有经济价值又能实现碳减排。
In order to realize low-carbon transformation in the energy industry and achieve the"double carbon"goal as scheduled,renewable energy represented by biomass has become increasingly attractive.Biomass gasification is a thermochemical treatment technology,which has seen rapid development in recent years.It is currently the most effective method for high-grade and efficient utilization of biomass energy.In this paper,the key units involved in the entrained flow gasification process,such as pulverization,transportation,and gasification were analyzed,and the feasibility of applying airflow bed technology to biomass gasification was demonstrated.Six typical agricultural and forestry biomasses were used as raw materials.Biomass entrained flow gasification simulation was carried out with the help of the Aspen Plus chemical process simulation software,and the coal and biomass co-gasification and biomass separate gasification processes were characterized.The carbon reduction effect of biomass gasification was analyzed.The results show that when a certain amount of biomass is added into coal,a good gasification performance is retained.With the increase of biomass blending ratio,the specific coal consumption gradually decreases,and the carbon reduction effect is apparent.Compared with traditional fixed bed and fluidized bed gasification,biomass entrained flow gasification has an advantageous calorific value of synthetic gas about 10 MJ/m^(3).It can be used as a surrogate for natural gas heating,which has economic value in achieving carbon reduction.This study is in line with the dual-carbon policy and also provides a reference for the efficient conversion and utilization of biomass.
