Optimization of Atmospheric Fluidized Bed Combustion Boiler by Computational Fluid Dynamics

Viscose rayon is a natural fabric from regenerated cellulose derived wood pulp, bamboo, or cotton linters. The viscose industry relies on electricity to generate steam for textile production. This study aims optimize the 45-ton-per-hour Atmospheric Fluidized Bed Combustion (AFBC) boiler. Its efficiency 78.16%, lower than benchmark of 85.78%. Boiler decreases as flue gas temperature increases, reaching 220 degrees Celsius, indicating suboptimal coal fuel utilization water heating. explores two controllable variables: calorific value and combustion air mass flow rate optimum efficiency. ANSYS Fluent 2021, Computational Fluid Dynamics (CFD) software, used analysis. calculated using indirect method following ASME PTC 4.0. research shows that adjusting increases 81.04%.
