一、前言 节能已成为世界各国普遍重视的课题。对各种依靠燃料燃烧供热的炉窑,例如:均热炉、连续加热炉、热处理炉和锅炉等,控制燃烧过程,提高热效率,降低燃料消耗,不仅可以获得直接的节能效果,而且由于产 I. Introduction Energy conservation has become a topic of universal importance in all countries in the world. For a variety of furnaces that rely on fuel combustion heating, such as soaking furnaces, continuous heating furnaces, heat treatment furnaces and boilers, etc., the combustion process is controlled, the thermal efficiency is increased and the fuel consumption is reduced, not only the direct energy saving effect is obtained,
