Current status of design and construction of ENCOAL Mild Gasification Plant
The ENCOAL project is demonstrating for the first time the integrated operation of several process steps: a. Coal drying on a rotary grate using convective heatin; b. Coal devolatilization on a rotary grate using convective heating; c. Hot particulate removal with cyclones integral solids cooling; and deactivation-passivation; e. Combustors operating on low-Btu gas from internal streams; f. Solids stabilization for storage and shipment; g. Computer control and optimization of a mild coal gasification process. The product fuels are expected to be used economically in commercial boilers and furnaces and to significantly reduce sulfur emissions at industrial and utility facilities currently burning high sulfur bituminous fuels or fuel oils thereby reducing acid rain-causing pollutants. The design and construction of the ENCOAL demonstration plan was done on a fast track basis, that is, these activities were extensively overlapped.
