Each radiant cell is 100 percent floor fired using state-of-the-art low-NOx burners.
The burners are designed to fire the plant residue fuel gas and/or natural gas import at 10 percent excess air. Each burner is equipped with an individual pilot burner. Draft required for combustion will be supplied by an induced draft (ID) fan located downstream of the convection-section breeching. Bridge-wall (radiant-to-convection transition) arch pressure is controlled by fan speed/damper operation to be slightly subatmospheric.
