燃油室式少无氧化加热炉的设计

The designing of box type furnaces of less or non-oaidation heating

文中简述了采用轻柴油在α=0.5条件下的燃烧实现工件少无氧化加热。在炉型结构的设计中利用了空气动力学分区原理,实现了燃料在炉膛内分层燃烧,并且达到了快速加热,提高了炉子热效率的目的。选择合理的燃烧装置,结合预热助燃空气的办法,提高了燃料的理论燃烧温度,满足工艺的要求,同时也回收了热量,节约了燃料。经生产的实际使用和热工测试表明炉子的各项技术经济指标比较先进。

In this paper a fuel furnace for less or non-oxidation heating by light diesel oil burning under the condition of α = 0.5, is discussed. In that furnace designing the zoning principle of aero-dynamics are applied, so that the burning in furnace chamber is layer by layer, the aims of rapid heating as well as the improvement of heat efficiency are being achieved. Choosing the reasonable burners integrated with air preheater the theoretic burning temperature of the fuel is raised, that is not only satisfying the technical requirements but also recovering afterheat and saving fuel. This furnace has advanced indexes of technique and economy, which have been proved by operation and the testing of heat engineering.
