油田注汽锅炉热效率普遍偏低,排烟热损失是影响锅炉热效率的主要因素,而排烟热损失决定于排烟温度和排烟量。国内目前对锅炉设备的改造技术多局限于减少锅炉的排烟梁上。本文论述了将冷凝技术应用在热力采油湿蒸汽发生器上来降低排烟温度,回收利用烟气中水蒸汽的汽化潜热,从而达到提高热效率的方法。 Oilfield steam boilers generally low thermal efficiency, exhaust heat loss is the main factor affecting the boiler thermal efficiency, exhaust heat loss depends on the exhaust gas temperature and the amount of smoke. At present, the domestic transformation of boiler equipment and more limited to reducing the boiler exhaust smoke beam. This paper discusses the application of condensation technology to heat steam production wet steam generator to reduce the exhaust gas temperature, recovery of water vapor in the flue gas latent heat of vaporization, so as to achieve thermal efficiency.
