介绍了新型百叶窗稳燃器的研究成果，此稳燃器结构简单、阻力小、改造费用低，它能使气、粉混合物喷入炉膛后立即形成有利于煤粉迅速升温着火的煤粉浓度场、气流速度场和温度场，出现高煤粉浓度、高速度梯度、高温区（以下简称三高区），使煤粉得以迅速升温着火，形成稳定的火焰（着火源），使燃烧稳定。 This paper introduces the research results of the new shuttered burner. The burner has the advantages of simple structure, small resistance and low modification cost. It can immediately form a pulverized coal concentration field that is conducive to rapid heating of the pulverized coal after the gas and powder mixture is sprayed into the furnace. , Air velocity field and temperature field, high pulverized coal concentration, high-speed gradient and high temperature zone (hereinafter referred to as “Three High” zones) occur. The pulverized coal can rapidly warm up and form a stable flame (ignition source) to stabilize the combustion.
