Abstract:
Cogeneration energy systems are one of the most promising clean, efficient technologies for satisfying industrial energy needs. In this study, a cogeneration system consisting of a solid oxide fuel cell, a gasification unit, a gas turbine cycle, and a steam network module is proposed. This topping system is integrated with a steam network that provides steam for different utilities by recovering steam. Also, biomass –as renewable energy– is used to address the problems of fossil fuels, such as scarcity of resources and environmental issues. The system is evaluated from an energy perspective to ascertain the feasibility of the system. Based on the results, the efficiency attained from this system is ۵۴.۳۵%. An optimization study based on a genetic algorithm is performed to find the best conditions, which indicates an efficiency improvement to ۶۵.۰۶%. Moreover, a parametric study on different steam network pressure levels is taken place, which shows the importance of the VHP header on system performance.
