Challenges when Converting Coal-Fired Boilers to – Babcock Power
When evaluating the prospect of converting a coal-fired boiler to natural gas, there economically appealing to consider using fewer burners with higher heat input to levels of NOx reduction while firing natural gas such that SCR and SNCR
Nitrogen Oxides Emission Control Options for Coal-Fired Electric
boilers have in- stalled SNCR, and reported NOx reductions achieved at design of burners and air registers, size of the furnace, firing configuration of the
