摘要：
该文以热力学第一定律和质量守恒定律为基础，通过分析大量的热力系统的结构特点，导出火电机组热力系统自适应汽水分布状态方程，该方程首次将热力系统的结构变化因素(如加热器解列、疏水方式的改变等)引入到了方程中，不但能适用于结构一定的任意形式的热力系统，而且能自适应于结构发生随机的、动态变化的热力系统。从而为热力系统的分析计算，特别是为结构发生动态变化的热力系统的理论分析计算和在线监测提供了一种新的工具。 |

Abstract:
On the basis of thermodynamics first low and mass conservation law, a self-adapted steam-water distribution equation for the coal-fired power unit is deducted through analyzing the structural feature of large number of thermodynamic systems. The structure-changing factors of thermodynamic system, such as splitting heaters and varying the way of drainage, are introduced in the equation, which make the equation applicable not only for any form of thermodynamic systems with fixed structure, but also for the systems with stochastic and dynamic structuring. As a result, it will be a new tool for the analysis and calculation of thermodynamic system, especially for the theoretic analysis and on-line supervision of structure-changing thermodynamic system. |
