摘    要:为了声学法电站锅炉温度场测量的需要,重点沦述了一种利用正则化方法对电站锅炉炉膛温度场进行重建的算法,并与最小二乘法温度场重建算法进行了比较。该算法与最小二乘法温度场重建算法的主要区别是通过在温度场重建中加入火焰先验信息,提高测量数据较少时温度场的重建精度,通过仿真考察了该算法与最小二乘法算法对不同温度分布函数的重建效果,结果表明该算法比最小二乘法温度场重建算法具有较高的重建精度,用该算法可通过较少测量数据快速而较高精度地实现电站锅炉炉膛二维温度场的重建。

关 键 词:声学法  电站锅炉  温度场  算法  正则化  图像重建  温度测量

Abstract:To measure temperature field of power plant boilers with acoustic method, reconstruction algorithm with regularization method is presented in this paper and compares with the reconstruction algorithm of temperature field commonly used in the least square method. The main difference between this algorithm and the reconstruction algorithm used in the least square method is that this algorithm increases the reconstruction accuracy by applying a priori information of flame during the reconstruction of temperature field when there are few data. Computing simulation examines the effect of reconstruction of temperature field with different temperature distribution functions of this algorithm and the least square method, as a result, this algorithm is more accurate than the least square method. This algorithm can implement 2-D temperature field reconstruction in power plant boilers with the algorithm fast and accurately without measuring a lot of data.
Keywords:regularizatiori  reconstruction algorithm  2-D temperature field  image reconstruction
