论文题目:劣质煤的燃烧与调整

摘 要

我厂近段时间试烧劣质煤,在运行中出现燃烧不稳定及受热面结焦现象,我们先后进行了多次研究与分析,在结合劣质煤的特点以及锅炉燃烧理论分析的基础上,初步摸索出了采用集中燃烧、改善一、二、三次风等一些燃烧调整手段,基本上达到了我们的预期目的。现将分析及解决方法总结如下,仅供参考与借鉴。

Title: Inferior coal combustion and adjust

ABSTRACT

Combustion instability and heating surface burns phenomena occur in our factory as a result of burning inferior coal.Many research and analysis are conducted to figure out the combustion adjustment ways of adopting concentrated combustion and improving first,second and third wind on the basis of the characteristics of poor-quality coal and boiler combustion theory,and basically we achieve the desired result.Now the analysis and solving methods are summarized as follow as a reference.
