Under the US Department of Energy (DOE) project ``Engineering Development of Advanced Coal-Fired Low-Emission Boiler Systems`` (LEBS) the ABB team developed the design of a 400 MWe advanced pulverized coal fired electric generating system. The work and the results are described in the paper. Early work included concept development and evaluation of several subsystems for controlling the emission of SO{sub 2}, NO{sub x}, particulates and for reducing wastes. Candidate technologies were then evaluated in various combinations as part of complete advanced supercritical power generation systems. One system was selected for the design of the advanced generating system. Pilot scale testing is now being conducted to support the design of subsystems. The design meets the overall objective of the LEBS Project by dramatically improving environmental performance of pulverized coal fired power plants without adversely impacting efficiency or the cost of electricity. Advanced technologies will be used to reduce NO{sub x}, SO{sub 2} and particulate emissions to one-fifth to one-tenth of current NSPS limits. Air toxics will be in compliance, and wastes will be reduced and made more disposable. Net station (HHV) efficiency can be increased to 45% without increasing the cost of electricity.
