WESNOR ABB ENVIRONMENTAL SYSTEMS DA VID J. BENDER RA YTHEON ENGINEERS & CONSTRUCTORS CONTRACT NO. DE-AC22-92PC92159 ABB Combustion Engineering, Inc. is one of three contractors executing Phases I, II and III of the Department of Energy project entitled Engineering Development of Advanced Coal-Fired Low-Emission Boiler Systems (LEBS). Phase I has been completed and Phase II is scheduled for completion on September 30, 1996. The following major activities are being carried out in parallel in Phase II and this paper is a status report on this work: In-furnace NOx reduction Catalytic filter optimization Add Kalina cycle to POCTF POCTF design and licensing The in-furnace NOx reduction work has been completed and, therefore, a description of this work comprises the major part of this paper. INTRODUCTION The primary objectives of the LEBS project are, using near-term technologies, to dramatically improve environmental performance of future coal-fired power plants while increasing their efficiency and maintaining the cost of electricity at or below current levels. The secondary objectives are to improve ash disposability, reduce waste generation and reduce air toxics emissions. The overall objective is expedited commercialization of the technologies developed. The major deliverables are a design data base and the preliminary design of a commercial generating unit (CGU). Since the award of contracts in September 1992 the DOE has asked the contractors to strive for ever lower emissions and higher efficiency. In addition ABB, with the addition of the Kalina cycle, has set an even higher efficiency target. Today the targets are as follows: DOE Minimum DO E Preferred ABB's Targeted Performance Performance Performance S02 * IblMM Btu 0.2 0.1 0.1 NOx IblMM Btu 0.2 0.1 0.1 Particulates IblMM Btu 0.015 0.01 0.005 Efficiency (HHV, net), % 42 42 45 * 3 lb SIMM Btu in the coal |
