Infrared Measurement of Combustion Temperature Using Water Vapor Emission ID: 2015-027

A novel, non-intrusive method for measuring combustion temperatures accurately using the infrared emission of water vapor.

Technology Overview

This technology introduces a groundbreaking approach to measure the temperature of combustion products by capturing the infrared emission of water vapor through a specially designed probe. The probe uses an optical lens to channel the infrared light into an optical fiber, transmitting it to a Fourier Transform Infrared Spectrometer (FTIR) for analysis. This method aims to offer a more accurate and less invasive alternative to conventional suction pyrometry, addressing its limitations and enhancing measurement reliability.

Key Advantages

• Non-intrusive measurement technique, preserving the integrity of the combustion environment
• High accuracy, with potential measurements within 2% under ideal conditions
• Reduction in calibration errors through specific wavelength band analysis
• Decreased equipment costs and enhanced ease of use compared to traditional methods

Problems Addressed

• Spatial and temporal averaging issues inherent in traditional pyrometry
• Difficulties and inaccuracies due to the intrusive nature of conventional temperature measurement methods
• Calibration errors and the challenge of background radiation in temperature measurement

Market Applications

• Industrial combustion systems monitoring and control
• Environmental monitoring to track combustion efficiency and pollutant formation
• Research and development in combustion science and engineering
• Quality control in manufacturing processes involving combustion
