The tar produced by biomass gasification can be challenging to handle in processing units. To address this issue, a new polygeneration structure based on tar combustion has been designed in this study. This structure has been developed using Aspen HYSYS software and consists of subsystems, including the tar combustion section integrated with a gas turbine cycle, a low-grade temperature section, a Goswami utility section, and a hydrogen production section. The products of this structure are 7920.65 kg/s of hot water, 33.52 kg/s of cold water, 0.56 kg/s of hydrogen, 4.444 kg/s of oxygen, and 222100 kW of power. The system is examined from various perspectives: energy, exergy, environment, and economics. The overall energy and exergy efficiencies are 89.72% and 54.53%, respectively. The exergy analysis exhibits a total irreversibility of 859,492 kW, in which the low-grade temperature section has the highest exergy destruction with a share of 72%. Accordingly, the environmental analysis demonstrates that the new process has zero indirect carbon dioxide emissions, and its footprint is equivalent to 0.22 kg_CO2/kWh. Also, the products have been produced according to economic estimates with a cost of energy of 0.0068 $/kWh and a total unit cost of products of 0.0274 $/GJ.

生物质气化产生的焦油在处理装置中可能具有挑战性。为了解决这个问题，本研究设计了一种基于焦油燃烧的新型多联产结构。该结构是使用Aspen HYSYS软件开发的，由子系统组成，包括与燃气轮机循环集成的焦油燃烧部分、低品位温度部分、Goswami公用设施部分和制氢部分。该结构的产品为热水7920.65 kg/s、冷水33.52 kg/s、氢气0.56 kg/s、氧气4.444 kg/s和功率222100 kW。该系统从多个角度进行审查：能源、火用、环境和经济。总体能源效率和火用效率分别为89.72%和54.53%。火用分析显示总不可逆性为 859,492 kW，其中低温段火用破坏最高，占72%。据此，环境分析表明，新工艺间接二氧化碳排放量为零，其足迹相当于0.22公斤_二氧化碳/千瓦时。此外，这些产品是根据经济估算生产的，能源成本为 0.0068 美元/kWh，产品的总单位成本为 0.0274 美元/GJ。
