水平浓淡煤粉燃烧器的研究

文中对四角布置的水平浓淡煤粉燃烧器进行了试验研究和理论分析，并与ＷＲ燃烧器进行了对比性研究。结果表明：水平浓淡燃烧器比ＷＲ燃烧器的着火提前、着火稳定性的调节范围更宽广。同时，深入分析了浓淡煤粉燃烧器稳定着火的机理，对最佳煤粉浓度进行了定量分析、计算结果与本试验数据的偏差为１７．４％。

A study of Horizontal Dense-dilute Pulverized Coal Burners

An experimental study and theoretical analysis has been conducted of horizontal dense dilute pulverized coal burners installed in a tangentially fired boiler.A comparison with WR burners has shown that the horizontal dense dilute burners enjoy an earlier than expected ignition and a more wide regulation range of ignition stability.Moreover,an in depth analysis has been performed of the mechanism of stable ignition of the dense dilute pulverized coal burners.Conducted also is a quantitative analysis of the optimum pulverized coal concentration.The calculation results deviate from those of the experimental data by 17.4%.
