Abstract
In this paper, a 300MW coal-fired generating electricity unit was studied. Under the certain ratio of load as 100%%, 9 80% and 67% conditions, air-staged air supply method was adopted. Kept the same oxygen concentration in the outlet of hearth, changed the supply style of air. The air dynamical distribution was changed. Under the same load, some air-staged supply methods were adopted to study the NO x emission with air staged. Flue gas analyzer was used to test the NO x concentration at the outlet of electrostatic dust catcher. Results indicated that under the same capacity condition, the air supply method could affect on NO x emission. For one load condition, there was a best air supply style with lowest NO x emission.
