burning diesel boilers can be used low nitrogen alternatives
Boiler Fuel - an overview | ScienceDirect Topics
The important characteristics of the reburn fuel are low nitrogen and high volatility. Natural gas and low-nitrogen fuel oils meet these criteria. Coal may be applicable if it is low in nitrogen can be dispersed evenly in the furnace and can be burned out within the available residence time.
When firing fuel oils NOx formed by fuel-bound nitrogen can account for 20-50% of the total NOx level. One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas

Using ULSD fuel and advanced exhaust emission control systems can reduce vehicle particulate emissions by up to 90% and emissions of nitrogen compounds (NOx) by 25% to 50%. ULSD fuel helps reduce emissions in older engines as well.
