Biomass plays a crucial role as both a primary and renewable energy source, contributing significantly to China′s low-carbon and sustainable development in the energy sector. Gasification, an efficient and clean technology for biomass energy utilization, is of great importance. The design of gasifiers critically influences the operational effectiveness of biomass gasification systems. This paper reviews the types, design parameters, and research status of biomass gasifiers, both domestically and internationally. The paper first introduces various biomass gasifier simulation methods, including traditional empirical models, artificial neural networks, and other techniques. These methods provide an in-depth understanding of key parameters in the gasification process. Furthermore, the paper explores different design methods for biomass gasifiers, such as empirical, semi-empirical, and reverse design methods. These design methods aim to improve gasifier efficiency and promote production sustainability. The paper highlights the significance of biomass gasifier simulation and design methods in advancing renewable energy. It also discusses future development directions for biomass gasifier simulation and design, aiming to provide a valuable reference for technological innovation and practical applications in this field.
