| 摘 要： | 本文基于现场试验结果,深入分析了火电站除氧器内各部分工质在动态过程中的质量变化和热量变化,根据能量守恒和质量守恒基本原理建立了较为精确的动态数学模型,并首次采用积分形式表示汽化深度。数字仿真结果表明,所建模型能正确反映除氧器在不同工况时的动态特性,可以用于火电站数字仿真、现场运行控制以及研究除氧器特性等方面.

| Abstract: | Based on the results of field test, the mass and heat transfer in a deaerator used in power plants is discussed in this paper. The mathematical model consisting of differential equations is developed on the principles of conservation of mass and energy, and a new formula of the evaporating depth is derived. The digital simulation shows that the model can describe the dynamic process of the deaerator accurately, and can be used for the simulation and control of power plant. |
