本文介绍了《MLP型煤粉燃烧咀》的研究结果。MLP型烧咀是一种新型燃烧器,借助于简单的机械结构,在MLP烧咀上可实现两种形式的火焰—平展形及火炬形火焰。本烧咀的点火性能良好,炉内温度均匀。煤粉的燃烧质量比较高,煤灰中的残碳小于1.5％。应用于平焰时,排出炉外的煤灰只占25％,而应用火炬式火焰时为50％。对于长炉身炉子,MLP烧咀也能用于贫煤的燃烧。 This article describes the “MLP pulverized coal burner” research results. The MLP burners are a new type of burners. With a simple mechanical structure, two forms of flame-flat and torch-shaped flames can be realized on the MLP burners. The burned nozzle ignition performance is good, the furnace temperature is uniform. Pulverized coal combustion quality is relatively high, residual carbon in coal ash is less than 1.5%. When applied to a flat flame, only 25% of the ash is discharged outside the furnace, compared to 50% when a flare flame is used. For long shaft furnaces, MLP burners can also be used to burn lean coal.
