自动点火燃烧器的研制与应用

Development and application of autoignition burner

钻井、井下作业及油井测试过程中将产生含有较多甲烷、乙烷以及少量易挥发的液态烃及微量的二氧化碳、氮、硫化氢等杂质的伴生气,给安全生产带来重大隐患。为了解决该问题,研发了自动点火燃烧器,该装置用太阳能电池板提供能源,当伴生气压力超过0.1 MPa时,控制系统自动打火点燃液化气,引燃燃烧区内伴生气。现场应用表明,该燃烧器结构设计合理,拆装、运输方便,使用过程中不产生明火,比以往同类手动产品更加安全可靠。

Drilling, downhole operation and oil well testing will generate associated gas which has high content of methane, ethane, small content of volatile liquid hydrocarbon as well as trace amount of carbon dioxide, nitrogen, hydrogen sulifde and other impurities, bringing about major hidden danger to production safety. An autoignition burner is developed, which adopts solar panel to provide energy. When associated gas pressure exceeds 0.1 MPa, control system will enable automatic ignition to ignite liqueifed gas combustion rod, thus to ignite the associated gas in combustion area. It is shown from ifeld application that the burner features reasonable structure design, convenient assembly or disassembly and transportation, and is not easy to generate open ifre, thus the burner is safer and more reliable than previous similar manual products.
