摘　　要：本文以实际工程为例,通过循环流化床锅炉外置式空预器疏水至大气式除氧器系统的热平衡计算得出,在不同工况下,为了避免除氧器发生自生沸腾,需考虑预留空预器疏水扩容器后疏水至疏水箱的管路;为了保证除氧器热力平衡,建议外置式空气预热器时,宜提高除氧器压力,可为以后设计提供理论计算上的参考。Based on a practical engineering example, By circulating fluidized bed boiler external air preheater hydrophobic to atmospheric deaerator, heat balance is calculated, under the different conditions, in order to avoid the occurrence of spontaneous boiling deaerator need to consider setting aside the air preheater hydrophobic expansion after hydrophobic to drain tank pipe.In order to ensure deaerator thermodynamic equilibrium, the proposed external air preheater, it is desirable to improve the oxygen pressure, can provide a reference for future theoretical calculations on the design.
