Commonly used strategies for natural gas-fired boiler burners include staged combustion, flue gas recirculation (FGR), flame temperature adjustment, and combinations of these approaches. These reduce NOx emissions from previous levels of 80-150 ppm of NOx to less than 30 ppm.
For example, the calculation of the total annual NOx emissions for an 800 hp boiler operating 24 hours/day, 365 days/year and having a NOx level of 110 ppm would be as follows. Emission Factor = 0.13 lb/MMBtu (110 ppm = 0.13 lb/MMBtu) Boiler Input = 33.5 MMBtu/hr (Based on 80% Efficiency)

We observed that the CaS destroyed fuel-NOx to “single digit ppm levels” right in the initial combustion step - 20 to 30 inches from the burner face. Rockwell now had a new coal-fired burner concept with SO 2 and synergistic NO x control . We now describe it as the CLEAN COMBUSTION SYSTEM. 6
How is NOx Formed. In industrial boilers, NOx is primarily formed in two ways: thermal NOx; fuel NOx . Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils.
Example: The TPM emissions being released from the stack are the result of combustion in a bituminous coal fired boiler. The stack testing results were based on a one hour test period.

High volatile content increases the flame temperature so as to contribute to NOx formation and emission. As another factor, for a pulverized coal fired boiler, the particle size of coal also influences on the NOx emission properties. Generally, there is a critical diamond for minimizing NOx emission for a given type of coal.
