Abstract:This paper conducted a feasibility experiment on mixed burning lowashfusion coal in 300MW unit boiler and studied each important monitored parameter and boiler agglomerating under different load conditions, maximal oxygen uptake and type of air distribution. The result shows that the surface of boiler tend to coke after mixed burning lowashfusion coal. However, through adjustment of type of air distribution, coking phenomenon was decreasing, which increased the effectiveness of boiler.
