锅炉重质燃油掺水系统的含水计量

Water Content Measurement for Boiler's Heavy Fuel Oil Water Mixing System

重质燃油掺水燃烧技术可以降低燃油粘度 ,使雾化均匀 ,而且在燃烧过程中 ,乳化油中的水分子在高温下分解为H2 和O2 并参加助燃。根据试验得知 ,在掺水量不大于 30 %的情况下 ,燃油的燃烧热值基本不受影响 ,从而达到节约能源 ,降低排放污染的目的。为保证加水乳化后燃油的含水稳定 ,必须依靠可靠的含水在线测量及相应的自动控制系统。燃油自动掺水系统在胜利油田井下作业公司锅炉队安装使用一个冬季 ,效果良好 ,达到设计要求。

This article introdues boiler's heavy fuel oil water mixing system composed of short wave water content transducer.In order to ensure the stability of transducer metering it should be far from the high temperature fluid and the automatic control system should carry on the redundancy design to ensure the normal operation of the system at any circumstance.
