CO Measurement in Coal Fired Plants | Yokogawa America

Too little excess air will result in a "fuel rich" situation producing a flue gas containing unburned combustibles (carbon monoxide, soot, smoke, coal). This situation results in a loss of efficiency because not all of the potential energy of the coal is captured in the combustion process resulting in fuel wastes.
