Combustion mechanism of pulverized coal injected into blast furnace and its simulation

摘要

The combustion behaviour of pulverized coal injected into the blast furnace has been observed using high-speed camera The combustion flame is not uniform across the cross-section and fluctuates with space and time. Ways to improve the combustibility are indicated. A one-dimensional mathematical model has been developed. This influence of particle dispersion and lance arrangement can be simulated.
