本文从连续介质流的守恒方程组出发,研究了质量交换,热量交换和动量交换强化的方法,指出在燃烧初期局部狭窄区域内若能扩大速度梯度、压力梯度, 浓度梯度和温度梯度的“四大差别”,就有可能实现劣质煤粉的高强度燃烧.文中以大量的冷态和热态试验结果,特别是钝体燃烧器、可控涡燃烧器和稳燃腔燃烧器的最新成果论达了上达理论的正确性. In this paper, starting from the conservation equations of continuous media flow, the methods of mass exchange, heat exchange and momentum exchange enhancement are studied. It is pointed out that if the velocity gradient, pressure gradient, concentration gradient and temperature gradient Large difference ", it is possible to achieve high-intensity combustion of inferior pulverized coal.In this paper, a large number of cold and hot test results, especially the latest results of bluff body burner, controlled vortex burner and steady burner burner Up to the theory on the correctness.
