Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The unit being tested at Lake Road is Boiler #6 which serves Turbine #4. Boiler #6 is a positive pressure Babcock & Wilcox/1800 psig/1005°F, 980 MMBTU/HR cyclone boiler that fires a combination of coal, gas and tire derived fuel. The coal burned in this boiler is typically a blend of 80% subbituminous PRB coal and 20% bituminous low sulfur coal. Typically if coal is being burned 99% of the fuel input will be coal and 1% will be tire derived fuel.
The unit was installed in 1967. Turbine #4 has a gross capacity of 99 MW. The pollution control equipment on Boiler #6 is limited to an ESP for particulate/opacity and OFA for nitrogen oxide (NOx) control. The ESP on Unit 6 was rebuilt in the mid 1990’s to maintain compliance with opacity and particulate limits after the unit was switched to fire the predominantly PRB coal blend. The boiler was designed around burning 100% bituminous coal and now with the PRB – sub bituminous coal, the fly ash typically has a high Loss On Ignition (LOI) and can range from 10% to in excess of 80% LOI.
