河南某油田采油厂是一个以稠油热采为主的原油生产单位。热采专用注汽锅炉是稠油开采的主要设备,其主要特点为:1)注汽锅炉为高温、高压、无锅筒、蛇形管束结构的直流锅炉,额定压力为10MPa或17MPa。2)要求注汽锅炉产生良好的蒸汽品质,即蒸汽干度70%。3)采用PLC控制系统,具有自动点火、安全监测与报警、超温超压自动保护等功能。目前该厂在用注汽锅炉共26台,2009年燃料油消耗当量达到187808t标煤。通过对热采注汽锅炉系统能
An oil field production plant in Henan is a heavy oil-based thermal recovery of crude oil production units. Steam injection boiler is the main equipment for heavy oil production. Its main features are as follows: 1) Steam injection boiler is a high-temperature, high-pressure, no-boiler, serpentine tube structure of the DC boilers, rated pressure of 10MPa or 17MPa. 2) Steam injection boiler is required to produce good steam quality, ie 70% of steam dryness. 3) PLC control system, with automatic ignition, safety monitoring and alarm, over-temperature automatic over-voltage protection and other functions. At present, the plant uses 26 steam injection boilers. In 2009, its fuel oil equivalent reached 187,808 t of standard coal. Through the heat recovery steam boiler system can
