Front Wall Coal Burners in Large Capacity Boilers
Front wall burners need a stringent tuning when compared tangential burner. Any mal-functioning of one burner can cause an overall deviation in boiler performance. This deviation can be thermal, pollution levels, combustion completion or a combination of two or more factors. Any deviation in burner setting can be evaluated from the performance changes that occur during continuous operation.
