Based on the UP once-through boiler waterwall operated in Shanghai Shidong kou Power Plant,this paper calculates the deviation of flow rate and thermal imbalance in waterwall pauels under the condition that the flame center is drilted at different loads of 300MW, 260MW, 240MW and 210MW.
本文使用计算机辅助计算方法,以上海石洞口电厂投运的UP直流锅炉水冷壁为对象,在炉内火焰中心发生偏斜的非正常工况的热负荷分布以及机组负荷为300MW、200MW、240MW以及210MW的不同负荷下,计算水冷壁各管屏内工质的水力偏差及热偏差,并据此计算水冷壁管壁金属温度,以判断哪些管屏在哪些位置可能发生水冷壁爆管事故,并提出防止发生爆管事故的措施和机组的安全运行分析提供根据。

补充资料:直流


直流
Direct current

  直流(direet。urrent) ,仅按一个方向流过电路或设备的电流称为直流。与交流电压相比,直流电压的极性是不变的。直流电流相当于电荷沿着闭合的电路以不变的方向流动或位移。直流电流和电压的幅值可以恒定,也可以随时间变化。 蓄电池和旋转发电机产生幅值恒定的额定直流电压,整流器产生幅值随时间而变的直流电压。整流器把交流电压变换为脉动的直流电压。 通常电站不是广泛地将直流电输配给一般用户,相反,在需要直流电(d。)能的场所,是把商业上合用的交流电(ac)能整流为直流电能。 「罗布(D.D.Robb)撰]
