“…They constructed a gas-combustion chamber coupling system using waste wood as fuel to simulate gasification reactions, analyzing fluid flow and heat transfer. Muhammad et al [9] established the Reynolds mean Navier-Stokes equation, a vortex crack combustion model, and a modified k−ϵ model to forecast the temperature distribution and flow field in the gasifier, using wood particles as raw materials. Their analysis involved assessing various operating conditions, such as the number of air intakes, fuel air velocity, and moisture content in the feedstock, impacting the gasification outcomes.…”

The advancement of biomass-circulating fluidized bed (CFB) gasification technology in China for commercialization and industrial application is still in its initial stages, characterized by extensive theoretical studies; however, there is limited documentation of its actual industrial operational characteristics. This study analyzes the operational challenges encountered in a 5 t/h biomass CFB gasifier at a rice factory in Jiangsu Province, China. It examines critical issues emerging during the gasifier system’s actual operational process, including the obstruction of the feeding system, the measurement of pressure at point blockages in the dense phase zone, loop seal blockages, bed inventory leakage of the blast cap on the air distribution plate, and gasification parameter fluctuations. Practical improvement strategies and implementation plans are proposed to address these operational concerns. The outcomes of this analysis serve as a reference for the design and operation of biomass CFB gasifiers. Furthermore, they provide crucial guidance for more extensive large-scale implementation of biomass CFB gasifiers.
