本文从煤粉燃烧理论出发，采用试验的方法，研究了分流式驻涡煤粉燃烧器的气流结构、煤粉分布特征及燃烧机理。经过分流板和驻涡稳燃器的双重作用，在燃烧器出口处形成了一个高浓度煤粉和高温区，该区域内同时存在着最大的速度梯度、煤粉浓度梯度和温度梯度，从而使煤粉迅速着火，燃烧稳定。实际应用证明，这种燃烧器在提高锅炉的低负荷稳燃能力，节省燃油等方面具有显著作用。 Based on the theory of pulverized coal combustion, this paper studied the air flow structure, pulverized coal distribution characteristics and combustion mechanism of the split-flow vortex pulverized coal combustion burner by the experimental method. After the dual function of the manifold and the LPO, a high concentration of pulverized coal and high temperature zone are formed at the exit of the combustor. At the same time, the maximum velocity gradient, pulverized coal concentration gradient and temperature gradient exist simultaneously in the region, so that Pulverized coal quickly on fire, stable combustion. Practical application proves that this kind of burner has a significant role in improving the steady load capacity of the boiler under low load and saving fuel.
