摘　　要：通过试验和理论分析,应用一种改进的双色法,消除了由于在不同波长下火焰黑度的不同对测量精度的影响。给出了测量原理,并简要说明测量系统的组成。对试验炉的计算结果表明,此方法具有较高精度,是一种简单可靠的炉内温度测量方法,可运用于火焰的温度场计算和燃烧诊断。A method using color CCD directly to measure flame temperature distribution without reference points is applied. It can eliminate the effect made by the difference of flame gray at different wavelength. It is based on an improved two-color method. In addition, the system composition is given. Results of experiments on coal furnace indicate that the method is provided with efficient precision, it is simple and reliable to measure temperature in furnace, and it is applicable to calculate the distribution of temperature and diagnose combustion.
