Oct 07, 2010· This balance in the mill caused better combustion in the upper furnace while balanced mills made for a more balanced furnace. Optimized burner belt combustion contributed to …
Cofiring is achieved in these systems through different methods, but the principles of combustion are similar. In wall firing, the fuel is mixed with combustion air in individual burners. Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle.
While all these are regarding themillperformance, thecoal finenessandmillout let temperature also affect the boiler performance. Thecoal finenesshas an effect on the combustion performance like the bottom ash percentage combustibles when the plus 50 mesh percentage goes up. It has been very well established that in the case of tangential firing system, the percentage of combustibles ...
