在自行设计、搭建的小型加热炉中分别对氧化烧损和节能效果及其最佳条件进行了较系统试验。结果表明:富氧技术在加热炉节能和提高加热炉效率方面具有优势,通过控制助燃空气中的氧浓度,可以减少煤气消耗和氧化烧损;通过对比钢坯氧化烧损在不同氧浓度的变化情况得出,富氧率控制在8%~12%时氧化烧损最小;在富氧条件下,都有不同程度的节能效果。
In the design and construction of small heating furnace, respectively, the oxidation burning and energy saving effect and the best conditions for a more systematic test. The results show that the oxygen enrichment technology has advantages in saving energy and improving the efficiency of the heating furnace. By controlling the oxygen concentration in the combustion air, the gas consumption and the oxidation loss can be reduced. By comparing the changes of the oxygen burning rate It is concluded that the oxygen oxidation loss is the smallest when the oxygen enrichment rate is controlled between 8% and 12%, and the energy saving effect is all under different oxygen enrichment conditions.
