Abstract: Abstract:Taking the 350MW coalfired boiler in a power plant as research object, through site test, the temperature distribution in the furnace was recorded. The influence of the oxygen content variation on combustion and coking of the boiler was analyzed. The target of this paper is to find the law of influence of the oxygen content on east Junggar coal combustion and to provide certain reference for east Junggar coalfire power plant to select proper oxygen content.

Key words: Keywords:east Junggar coal, design parameter, cooking, oxygen content test, temperature distribution, data analysis
