控制燃烧控制燃烧在炉子操作上是最重要的。在日常工作中可通过简单仪表的检测,就可较大的提高节能效果,但一般都不被重视。如控制空气比时,不进行气体分析,而是用目测来调节,这样在燃烧时含氧量偏差大,使之不经济。燃料完全燃烧所需的空气量与燃料种类有关,不同燃料有不同的理论空气需要量。对实际炉子,用理论空气量获得完全燃烧是困难的,通常加入5～10％的过剩空
Controlling combustion Controlling combustion is most important in furnace operation. In daily work can be detected by a simple instrument, you can greatly improve energy efficiency, but generally not be taken seriously. Such as the control of air ratio, no gas analysis, but with visual adjustment, so that when the oxygen content in the combustion deviation, making it uneconomical. The amount of air required for complete combustion of the fuel is dependent on the type of fuel, with different fuels having different theoretical air requirements. For practical furnaces it is difficult to achieve complete combustion with the theoretical air volume, usually adding 5 to 10% of excess space
