一、前言我厂平炉自1965年燃用重油以来,在全国同类平炉中仍属油耗较高者。油耗较高的主要原因除在生产管理和技术操作上存在一些问题外,重油消耗的计算方法不合理也是其中的原因之一。众所周知,重油重量流量的关系式为: G=Vtdt t/h (1) 式中:Vt—— t℃时油的体积流量, I. INTRODUCTION Since our plant was started burning heavy fuel oil in 1965, it is still the highest fuel consumption in similar open hearth furnace in the country. The main reason for higher fuel consumption In addition to some problems in production management and technical operation, the unreasonable calculation of heavy oil consumption is also one of the reasons. As we all know, heavy oil weight flow of the relationship as follows: G = Vtdt t / h (1) Where: Vt-- t oil volume flow,
