The usual indicators are increases in the temperature and in the oxygen (02) concentration at the stack. Proper excess air levels range from 20 to 30 percent for pulverized-coal- fired boilers. The excess air level for best boiler efficiency is generally one that produces a very low carbon monoxide (CO) concentration.
