Propose and Analysis of an Integrated Biomass Gasification-CHAT-ST Cycle as an Efficient Green Power Plant

摘要

Advanced combined cycles using gas turbine and bottoming cycles have been developed to improve energy efficiency and output power of the conventional thermal power plants. In this study, integrated biomass gasification-cascaded humidification advanced turbine and steam turbine cycle have been presented as a novel approach to reach out the sustainable energy vision. All generators of this comprehensive system operate by syngas produced from biomass gasification. Based on the technical consideration, modeling and simulation of the mentioned cycle have been performed, which results indicated more than 33.6 MW power generation and about 56.4% total efficiency in the base case. Moreover, parametric studies demonstrated the considerable dependency of the delivered power, specific fuel consumption, and heat rate to ambient temperature variations. In addition, principal parameters changes due to the fluctuation of the gasification temperature demonstrated an obvious increase in fuel consumption rate after crossing a turning point. Eventually, other achievements such as the negative effect of biomass moisture increase on cycle outputs, and also, advantages of turbine inlet temperature rise have obtained by plant analyzes.
