Ultra-low emissions gas turbine combustion system program. Progress report, July 1, 1993--February 28, 1994

摘要

The Santa Barbara County Air Pollution Control District (SBCAPCD) has arranged a consortium to develop ultra-low emissions combustor technology applicable to gas turbines. The goal of the program is to develop and demonstrate a safe, efficient, and cost-effective method to meet a 9 ppmv NO(sub x) emission limit for gas turbines. Currently this emission limit can only be met with the selective catalytic reduction (SCR) technology (a post combustion cleanup process that is capital intensive and maintenance intensive). In coordination with a comprehensive technical advisory committee, SBCAPCD has evaluated different potential low emissions technologies and decided upon a lean premix approach to retrofit existing turbines and to integrate with new engines. This technology will provide a low cost alternative to the expensive controls and will substantially reduce NO(sub x) emissions from gas turbines. The design, fabrication and testing of the ultra-low NO(sub x) combustor system is currently being performed by Allison Gas Turbine Division, General Motors Corporation. This project continues to be overseen by a technical advisory committee to ensure timely and cost-effective product delivery.
