The invention discloses an oxygen-enriched combustion method of a high-purity magnesia shaft kiln. The method comprises the following steps: S1, arranging an air separation mechanism outside the high-purity magnesia shaft kiln to obtain oxygen-enriched air; S2, arranging a preheating mechanism at the exhaust port of the air separation mechanism in S1 to increase the temperature of the oxygen-enriched air; S3, arranging a pressurizing mechanism at the exhaust port of the preheating mechanism in the S2to compress high-temperature oxygen-enriched air; and S4, respectively arranging a group of high-temperature-resistant air supply mechanisms in the combustion areas with different heights of the high-purity magnesia shaft kiln for conveying high-temperature oxygen-enriched air into the combustion areas with different heights of the high-purity magnesia shaft kiln. Compared with a common air combustion technology, the designed oxygen-enriched combustion technology has the advantages that thecombustion temperature is very high, the combustion speed can be increased, the complete combustion is promoted, a relatively small excess air coefficient can be adopted, the smoke exhaust amount isreduced, the fuel amount is reduced, and the nitrogen oxide emission is reduced, and the like, so that the oxygen-enriched combustion technology is widely applied to industry.
本发明公开了一种高纯镁砂竖窑的富氧燃烧方法，包括以下步骤：S1：在高纯镁砂竖窑外部设置一空气分离机构，用以获得富氧空气；S2：在S1中所述的空气分离机构的排气口处设置一个预热机构，用以提高富氧空气温度；S3：在S2中所述的预热机构的排气口处设置一个增压机构，用以压缩高温富氧空气；S4：在高纯镁砂竖窑的不同高度的燃烧区域分别设置一组耐高温送风机构，用以向高纯镁砂竖窑的不同高度的燃烧区域内输送高温富氧空气。本发明设计的富氧燃烧技术与普通空气燃烧技术相比具有很高的燃烧温度，能够加快燃烧速度，促进燃烧完全，可以采用较小的过量空气系数，降低排烟量，降低燃料量，减少氮氧化物排放等优点，使其在工业上得到广泛应用。
