Sensors for Natural Gas Combustion Control Systems: Market and TechnologyAssessment of Low-Cost Sensor Arrays for Combustion Monitoring and Control. Final Report of Phase 1, September 1991-August 1992

摘要

Market research and investigation of emerging gas concentration sensortechnologies were conducted in preparation for a program to develop low-cost sensor arrays for emissions monitoring and control. Those activities constituted Phase I of the program and are the subject of this report. Recent Federal and regional air quality regulations are discussed in the report. Projections are made about the effect of that legislation upon forthcoming emissions instrumentation needs of industrial and institutional natural gas users. Results are summarized of interviews with 198 industrial and institutional natural gas users who were polled to learn their experiences with combustion control instrumentation and their priorities for characteristics of new instrumentation. Literature and patent searches were made of oxygen, CO and NOx sensing technologies, and those most promising for low-cost sensor arrays are discussed. Comparative tests of various oxygen sensing technologies were made and the results reported. Recommendations for future product development are made.
