| 摘 要： | 1 Introduction 1 For pulverized coal injected into a blast furnace, the space from the outlet of the coal gun to the center of the raceway is the key district for the coal’s burning and also for works to probe hearth state. Remarkable achievements have been made in research on numerical simulation of combustion processes 1], but further advances are hindered owing to the limits of the means to examine three-dimension parameter distribution in the furnace. Temperature is the most basic parame…

| Abstract: | In order to establish correlativity between pulverized coal combustion in a blast furnace raceway and its radiant image, we investigated the relationships between two dimensional radiant images and three dimensional radiant energy in a blast furnace raceway, focusing on the correlativity of the numerical simulation of combustion processes with the connection of radiant images information and space temperature distribution. We calculated the uneven radiate characteristic parameterby taking radiant images as a kind of radiative boundary for numerical simulation of combustion processes, and put fonward a method to examine three-dimensional temperatures distribution in blast furnace raceway by radiant image processing. The numeral temperature fields matching the real combustion can be got by the numeric image processing technique. |
