A 70,000 lb./hr. coal-fired fluidized bed combustor is currently undergoing acceptance testing in Amarillo, Texas. Preliminary indications are that the gaseous emission levels are low: the SO/sub 2/ and No /SUB x/ emissions are well within the state's emission limits, while the burner operates at 20% excess air. The unit is able to continuously follow load changes to 1/3 of full load, at rates of 15% per minute. Below this, the burner is operated in a cycling mode. The FBC is a novel dual-bed design that enables it to achieve high desulfurizing efficiencies in a short (14 feet tall) package unit. The system also incorporates a package coal feed system that reduces costs in that area. Comprehensive performance measurements were started in March, 1983. A history of the development of the unit is included. Improvements over conventional FBC's were made in two areas, and the resulting system is called the Wormser Grate.
