摘要

本文介绍了火焰成像系统的软件开发和实验标定。新的系统软件是基于一个独特的架构,通过精心结合Visual Basic和Visual C编程策略开发的,以获得更好的系统稳定性和响应时间。成像系统使用高标准黑体光源作为温度/光参考,温度范围从800°c到1650°c,以提高火焰温度的测量精度。新的系统软件和校准曲线是通过离线分析来评估的,其中使用了以前在工业规模的煤燃烧测试设施上测试中捕获的火焰图像。给出并讨论了试验结果及其与在线数据的比较。

Digital Imaging Based Measurement of Combustion Flame Characteristics
This paper presents the system software development and the experimental calibration of a flame imaging system. The new system software is developed based on a unique architecture through a careful combination of Visual Basic and Visual C programming strategies for better system stability and response time. The imaging system is calibrated using high standard blackbody sources as temperature/light references over the temperature range from 800degC to 1650degC for an improved measurement accuracy of flame temperature. The new system software and calibration curves are evaluated through off-line analysis where flame images captured in previous tests on industry-scale coal combustion test facilities are used. Test results and their comparisons with online data are presented and discussed.
