的电功率Э_r。作者从研究背压机组无给水回热情况下的q_r出发,考虑了供热量Qпp,得到机组的电功率特性。然后再考虑机组的给水回热特性,导出机组的出力特性。综合上述关系式,最后得到背压机组经济指标计算的综合表达式。图1,表2,参5。(许仕圣摘)8701B002 缩短冷却过程对50万千瓦汽轮机组构件应力状态的影响《Energietechnik》,1986,No.4,142—147(德)苏联50万千瓦汽轮机组高压部分自然冷却过程需140～160小时,中压部分则更多。现用强制法加速冷却,可缩短60％的时间,
The electrical power Э_r. The author starts from studying the q_r without back-pressure back-flow in the back-pressure unit, and takes into account the amount of heat supply, Qp, to obtain the electrical power characteristics of the unit. And then consider the unit of water back to the heat characteristics, export unit output characteristics. Based on the above relationship, finally, the comprehensive expression for calculating the economic indexes of back pressure unit is obtained. Figure 1, Table 2, reference 5.

Accelerated use of coercive cooling can be shortened 60% of the time,
