煤粉浓度对着火区火焰稳定性影响的研究

Study of the Influence of the Pulverized Coal Concentration on Flame Stability in Ignition Zone

本文分析煤粉浓度对火焰稳定性的影响,并在煤粉燃烧试验台上进行了试验。试验表明,在试验煤粉浓度范围内,随着煤粉浓度的提高,着火区煤粉气流的火焰稳定性也提高。

The influence of the pulverized coal concentration onflame stability is analyzed and tested on the experimentalplant of pulverized coal—fired.The results showns that theflame stability of pulverized coal concentration airflow isincreased along with the raise of pulverized coal concentra-tion in experimental pulverized coal concentration range.
