聚能加热技术在大庆油田采暖系统中的应用

Technique of Energy-gathered Heating in Heating System in Daqing Oilfield

大庆油田为实现2010年能耗总量要比2005年下降120×104t标煤的节能目标,在采暖系统中试验应用聚能加热技术进行节能改造。介绍了聚能加热技术的原理及特点:与燃煤、燃油锅炉相比,热效率高(94%);省去了外部循环化验设备,可以利用峰谷电价差进行智能化管理;产热与热传输为同一介质,无污染,能抑制结垢物质在管道内壁和加热系统内壁的粘附;不需要其他任何加热元件,主要器件不属于压力容器设备,运行安全性高;采用微电脑自动控制,可单机或多机并列使用;安装简便,无需改动原有管线。大庆油田的现场应用案例表明,聚能加热技术适用于距离热源较远、相对独立的中小规模建筑(油田注水站、配注站、聚合物注入站、野外采油队等)的采暖需求,完全可以替代电采暖和锅炉采暖,节能效果显著,可有效降低运行费用和人工费用。

Technique of energy-gathered heating is applied in energy saving and reforming in the heating system for achieving the goal of decreasing by 120 ×104t coal equivalent in total energy consumption than 2005 in 2010 in Qaqing oilfield.The principle and character of the technique are introduced as follows.Compared with coal burning boiler and oil burning boiler,it has high heat efficiency up to 94%.Test equipment for external cycle does not need,and intelligentization administration may be made through power rate difference between peak and valley.Thermal producing and transmission is completed in the same media with no pollution,which will prevent adhere of scale forming material in inside wall of piping and heating system.No heater elements need,and main equipments does not belong to pressure container with high security in operation.Microcomputer is applied to automatic control by single or multiple ones.It fixes simply with the primary pipeline.The field application in Daqing oilfield shows that the technique of energy-gathered heating meets the heating demands for mid-small building with long distance to heat source and relative independence（oilfield injection plant,injection distribution station,polymer injection plant,field oil production crew and so on）.It can heating instead of electric heating and boiler heating with obvious energy saving effect and lower operation and manpower fee.
