Abstract

Abstract: A novel integrated structure is introduced in order to produce power and heat through biomass fuel simultaneously. This cycle has different sections including the gasification process, solid oxide fuel cell, gas turbine cycle, Rankine cycle, ORC, and hot air and water line. The heat required for the gasifier agent and the air is supplied through heat recovery in this system. In this article, wood chips are employed to supply the required fuel for a solid oxide fuel cell by gasification process. Also, the heat of the SOFC outlet stream is employed for heating the inlet streams of the Rankine cycle, gas turbine, and ORC. Both energetic and exergetic analyses are considered in order to evaluate the performance of the proposed cycle. A sensitivity analysis is performed for observing the effects of the operational parameters on the output power and overall efficiency of the system. The results illustrate that the output power of the cycle is 152.8 MW, and the electrical and overall efficiencies are 51.43% and 81.13%, respectively. Also, the highest portion of exergy destruction is allocated to the fuel cell, which is about 65 MW.
