| 摘 要： | 根据基本的质量和能量平衡关系,运用机理分析方法建立了直流锅炉的传热简化模型,通过严密的数学推导,得到了直流锅炉过热汽温与其影响因素的微分关系式,该关系式全面反映了影响过热汽温变化的各种因素,根据该式可分析过热汽温变化特性.最后对多台直流锅炉进行了热力计算,比较了各因素对过热汽温变化的影响.研究结论可为直流锅炉的运行控制和仿真提供理论指导.

| Abstract: | From the relationship of quality balance and energy balance,a simplified heat exchange model of once-through boiler is suggested with mechanism analytical method.A differential equation for the superheated steam temperature and its influencing factors which may lead to the variation of the superheated steam temperature is estalished based on this model through refined mathematical deduction.All factors which may affect the change of the main steam temperature are included in this differential equation,the f... |
