Why is intelligent boiler cleaning able to reduce NOx emission?
NOx emissions are a function of combustion temperature and amount of O2 in the combustion process. Typically Eldevich or thermal NOx production escalates at an exponential rate in areas where the local combustion temperature exceeds 2600 degrees Fahrenheit. The presence of hot and cold spots, such as indicated in the thermal profiles obtained from the HVT probes above will tend to indicate weak heat distribution in the combustion process and can be caused by a misdistribution of heat transfer in the furnace walls. This can be addressed by implementation of intelligent and dynamic boiler heat flux feedback mechanisms.
