注汽锅炉是油田稠油开采的主要设备。锅炉上燃油所使用的喷油嘴,90%以上是北美油嘴,该油嘴在多年注汽生产应用中,逐渐暴露出很多缺点。如:火焰发散,形状不规则;烟温上升快,瓦口易结焦;易造成炉管局部过热,缩短了锅炉炉管的使用寿命。在生产过程中,我们根据现场实际自行研制了一种新型喷油嘴——双旋流节能喷油嘴,本文将对其结构及现场使用情况进行介绍。
Steam injection boiler is the main equipment for heavy oil recovery in the field. More than 90% of the fuel nozzles used on the boiler fuel are North American nozzles, which have gradually exposed many shortcomings in many years of steam injection application. Such as: the flame divergence, the shape of irregular; smoke temperature rise faster, Watts easily coking; easy to cause local overheating furnace tube, shortening the life of the boiler tube. In the production process, according to the actual situation of the site, we developed a new type of nozzle - double swirl fuel nozzle, this article will introduce its structure and field use.
