摘要:
本文讨论了以往有关低循环倍率锅炉压力稳定性的文献;分析了强制循环系统中压力闭环的作用;从“过热器中吸热量不变”的假定出发,对强制循环系统的数学模型进行了补充修正,并对模型的简化提出了新的处理方法。通过大面积的数值计算证明:当压力小于200taa时,压力的动态响应总是稳定的,而且实际上不会反复振荡。因此,对压力响应来说,不存在一个“极限循环倍率”的问题。
Abstract:
In this paper some reeent artieles on the pressure stability of a sleam boiler with forced recirculation are discussed.The mathematical model of a forced- recirculation system is revised on the assumption of constant heat absorption in the superheater.A new treatment for simplifying the model is also pro- posed.Through a wide range numerical calculation it is proved that for boiler pressure below 200ata the pressure response is always stable and practically non-oscillatory.There is no lower limit,to the recirculating ratio.
