Abstract
The paper presents the impacts of the jet momentum, position and orientation of air and Recycled Flue Gas (RFG) streams on the performance of a grate-fired boiler burning waste wood via a comprehensive CFD-based parametric study. It is found that the air and RFG jets can be optimized to enhance mixing and improve combustion in the boiler. For instance, the optimized air and RFG jets can extend the residence time of the gas and entrained fine particles in the hot zones effectively, make the temperature and velocity profiles more uniform, and enhance heat transfer. The findings of this study can serve as useful guidelines for innovative design and optimization of the secondary air and RFG for this type of grate boilers.
