Babcock & Wilcox The Babcock & Wilcox Company developed a number of processes but is perhaps best
known for its coal gasication process. This uses a single-stage, two-zone gasier. In the lower zone, coal and
recycled char contact oxygen (or air) and steam at 1650°C–1855°C, and molten slag is removed from the base
of the zone. The upper zone is cooled to 900°C. A commercial scale oxygen-blown plant was operated in West
Virginia in the 1950s, and a pilot-scale air-blown plant was operated in Ohio in the 1960s. See also Bi-Gas.
