摘要: 以东方锅炉厂制造的超超临界1 000MW机组直流锅炉为研究对象,从质量和能量守恒方程出发,建立了中间点温度控制的非线性集总参数动态模型。使用小偏差法求解,得到直流锅炉在某一稳定工况附近变动时中间点温度变化量关于给水变化量、给煤变化量的传递函数。
英文摘要: Taking the once-through boiler equipped for ultra-supercritical 1 000 MW unit manufactured from Dong fang Boiler Works as the object of study and starting from the quality and energy conservation equation,a non-linear dynamic model of lumped parameters for the intermediary point temperature control has been established.By using a small deviation method to seek solution of the equation,the transfer function of the intermediary point temperature variation related to feed-water and feed-coal change has been obtained in the case of the once-through boiler being changed in the vicinity of one stable operating condition.
