铸造熔炼中燃料燃烧过程中占空气约７９％的氮气的存在对燃烧过程毫无益处，一方在它浪费了大量的热能，另一方面氮气在高温下还与氧气反应生成ＮＯｘ氮氧化物造成环境污染，腐蚀设备。引用全氧燃烧技术，就可能克服上述缺点。因此，有必要对铸造熔炼上采用全氧燃烧技术的应用和推广开展深入细致的工作。 The presence of nitrogen, which accounts for about 79% of the air during the combustion of the fuel during the casting process, provides no benefit to the combustion process, with one party wasting a large amount of heat energy on the other hand, and nitrogen also reacting with oxygen at elevated temperatures to form NOx NOx Pollution, corrosion equipment. Reference to oxygen combustion technology, it is possible to overcome the above shortcomings. Therefore, it is necessary to conduct in-depth and meticulous work on the application and promotion of oxy-fuel combustion technology in foundry smelting.
