Report of Visit to Woodall-Duckham, Pittsburgh Sales Office, Pittsburgh, Pennsylvania.
Enviro Control, Inc., Rockville, Maryland 1977 Aug:4 pages
This report described a visit to the United States Sales and Engineering Office of Woodall-Duckham in Pittsburgh, Pennsylvania. This company engineers and constructs first generation low Btu coal gasification facilities. The Woodall-Duckham gasifier could use most noncoking coals and could use coking coals which produce coke buttons up to a limit of 2.5. The furnace ran with a flooded feed and required attention to make certain that the coal did not bridge in the bed. To prevent this the unit had a number of rod out holes located in the top of the furnace. These were designed to prevent noxious gases from blowing into the operator's face. More elaborate clean up procedures also could be provided. The tar recovered from the unit was apparently much lighter in quality than tars from the Lurgi or Wellma-Galusha units.
