Formation and Destruction of N sub(2)O in Pulverized Fuel Combustion Environments Between 750 and 970 degree C

Dilute pulverized coal combustion conditions were maintained in an entrained-flow reactor to study nitrous oxide formation and destruction. No N sub(2)O evolution was observed at temperatures exceeding 950 degree C. At oxygen concentrations below 1.5% and in the presence of carbon monoxide, N sub(2)...

description Dilute pulverized coal combustion conditions were maintained in an entrained-flow reactor to study nitrous oxide formation and destruction. No N sub(2)O evolution was observed at temperatures exceeding 950 degree C. At oxygen concentrations below 1.5% and in the presence of carbon monoxide, N sub(2)O already formed was rapidly destroyed above 900 degree C and fairly rapidly even at 830 degree C. Destruction proceeded more slowly at high oxygen concentrations, with no destruction below 900 degree C. A low O/N ratio of coal favored N sub(2)O formation.
