  "id": "MLC-T-ENV-023276",
  "term": "Reburning",
  "field": "Environment",
  "definition": "Reducing the coal and combustion air to the main burners and injecting a reburn fuel (such as gas or oil) to create a fuel-rich secondary combustion zone above the main burner zone and final combustion air to create a fuel-lean burnout zone. The formation of NOX is inhibited in the main burner zone due to the reduced combustion intensity, and NOX is destroyed in the fuel-rich secondary combustion zone by conversion to molecular nitrogen.",
