石油、化学工业和其他许多工业一样,其工艺过程都广泛使用加热炉。在工厂消耗的能量中,加热炉占有很大的比重,个别工厂中甚至占总能量消耗的70%以上。因此,如何改善加热炉的操作、提高加热炉的热效率对增加生产、降低热能消耗和降低产品成本都有着重要的意义。一、加热炉热效率的确定加热炉使用的燃料中可燃成分有 H、C 和少量的 S、O 等。在加热炉的计算中,一般用燃料的低热值(L、H、V)即所谓净发热值。而液体燃料和气体燃料的低热值可用多种方法计算,亦可由实验测出。最简便的方法是查有关物化手册。
The petroleum, chemical industry, like many other industries, uses furnaces extensively in their processes. In the energy consumed by the factory, the furnace occupies a large proportion, even individual plants account for more than 70% of the total energy consumption. Therefore, how to improve the operation of the heating furnace and improve the thermal efficiency of the heating furnace is of great significance to increase the production, reduce the thermal energy consumption and reduce the product cost. First, determine the heating furnace thermal efficiency The fuel used in the furnace combustible components H, C and a small amount of S, O and so on. In the calculation of the furnace, the general use of low heating value of fuel (L, H, V) is the so-called net calorific value. The low calorific value of liquid fuels and gaseous fuels can be calculated by a variety of methods and also experimentally measured. The easiest way is to check the materialization manual.
