Study of relationship between supercharged boiler's furnace temperature, radiant rate and boiler's operation parameters

摘要

In this paper, visualization detection technology of supercharged boiler's combustion in furnace is been used to take photo of the flame in furnace, and calculate temperature images and radiant rate images corresponding to flame images, and get average temperature and average radiant rate value, and gain relationship between average temperature and average radiant rate value. Studies show that: according to image of flame in furnace taken in different working conditions, average temperature and average radiant rate value have the same change rule. Working condition of boiler is higher, fuel consumption and radiant temperature are higher, and average radiant rate is lower, and operation parameters such as fuel press, steam temperature and pressure difference of gas are higher, and vice versa.
