STEPHEN C. WOOD

Principal Officer

BACKGROUND

Mr. Wood has been responsible for analytical studies, boiler and process heater performance-availability-reliability optimization, and combustion generated air pollution reduction programs on several hundred utility and industrial combustion devices throughout the United States and Europe. He has worked with numerous utility and industrial clients to achieve compliance with state and local NOx emissions regulations. He has also been responsible for testing, combustion process modification and optimization, development of optimum NOx Control Strategies, selection of retrofit NOx Control Technologies, and preparation of compliance plans. In conjunction with his NOx emissions control and performance improvement work, Mr. Wood has authored numerous technical articles on NOx control technology, combustion process and energy utilization. He has also developed training manuals and conducted courses and work shops for various government, electric utility, refinery, petrochemical, and industrial clients on such topics as: combustion generated air pollution control; boiler efficiency and plant performance improvement; and burner systems and fuels. Mr. Wood owns U.S. Patent No. 4,730,911, "Wide Angle Optical Viewer", issued in 1988. He is also the co-inventor of the Induced Flue Gas Recirculation (IFGR) and Slip-Stream FGR technologies, which have been granted patents by the U.S. Patent and Trademark Office. (No’s 6,599,119 & 6,609,907).

EXPERIENCE

Mr. Wood has over 37 years of combustion related engineering experience and has been responsible for technical and business development operations at several companies offering combustion related products and energy services. He developed and directed numerous performance/availability/reliability and energy utilization programs for various electric utility, refinery, petrochemical, and industrial clients. Implementation of these programs produced significant improvement in equipment performance and reduction of energy losses.

He has developed an innovative combustion diagnostic technology that provides real-time, accurate assessment of in-furnace combustion performance. This technology has been applied with remarkable results to a wide variety of combustion devices firing natural gas, landfill gas, refinery gas, oil, coal, lignite, and fuel blends. This development provided the basis for implementing advanced "Deep Staged" off-stoichiometric combustion optimization programs for control of NOx emissions from a number of utility boilers in California. He also designed and implemented burner system modifications for performance improvement and emissions reduction on a number of utility and industrial boilers. He was responsible for implementing off-stoichiometric firing on a system wide basis for Houston Lighting & Power in the mid-1970's. He was also an Edison Electric Institute's - Utility Air Regulatory Group - NOx Control Technology subcommittee consultant during the 1978 NSPS rule making. His technical work and presentations regarding NOx control technologies and assessment of their impact on utility boiler operations, performance and availability resulted in promulgation of the Environmental Protection Agency's NOx emissions New Source Performance Standards which were more realistically achievable.

He pioneered the application of Induced Flue Gas Recirculation (IFGR) technology for NOx control to large central station boilers. He has developed, designed and optimized IFGR systems on a number of utility and industrial boilers, including the first IFGR application on a large central station utility boiler. He has been responsible for the design and installation of over 45 IFGR systems, including electric utility, refinery, petrochemical, industrial, paper mill boilers, and gypsum kilns. The unit capacities ranged from 8,150 to 15 mmbtu input. Although the size and design of combustion equipment varied greatly, the NOx emissions reductions achieved comparable results.
