Numerical Simulation of Combustion in 35 t/h Industrial

Coal-fired industrial boilers should operate across a wide range of loads and with a higher reduction of pollutant emission in China. In order to achieve these tasks, a physical model including two swirling burners on the front wall and boiler furnace was established for a 35 t / h pulverized coal-fired boiler. Based on Computational Fluid Dynamics (CFD) theory and the commercial software ANSYS Fluent, …

Development of pulverized biomass combustion for

Pulverized biomass has been adopted for co-firing with pulverized coal in the furnace of an industrial boiler for power generation and process steam. Yi et al. (2013) conducted a study with thermogravimetric analysis (TGA) on a blend of ramie residue and coal. The effects of coal blending ratio from 0 to 30 wt% on performance of cyclone furnace were investigated.
