Design of co-gasification from coal and biomass combined heat and power generation system

摘要

The objective of this work focuses on designing a co-gasification process using Aspen Plus. The effect of co-gasification of coal/ torrefied biomass blends of 0, 20, 40, 60, 80, 100% w/w torrefied biomass content was evaluated. To evaluate the potential application of torrefied wood, an integration of co-gasification with CHP (combined heat and power) plant for heat and electric power production is also carried out in this simulation model. The simulation result shows that the gas turbine provided 1352.55 kW net power output and the efficiency up to 58.94 % when the BR ratio of 80 wt% is conducted.
