Def Fluid LIfe

DEF
Urea.......32.5%
Water......67.5%
Boiling point............. >212*F
Crystallization Point..... 12*F
We used it at powerplant back in 1995 as a R&D Project.
Sprayed under high pressure into flame patterns in boiler to reduce stack emissions. What a pain. Flame temp had to be correct or the urea would convert to ammonia so we had three levels of nozzles that were used depending on where flame pattern was.
Tested the system for little over a year then abandoned in place when DOE monies ran out.
It DID reduce Nox Emissions but cheaper method with less involvement lowered the Nox better. Firing the boilers using a 'lean flame' ----simple and no new equipment needed just training.
After my experience with it on a commercial scale glad to hear it is basically fill it/forget it
