1.7145 K30DG1000/170-1型锅炉汽包强度试验研究(东方锅炉厂)通过对该厂首台300MW机组锅炉汽包强度评定,对汽包下降管接头结构和选材提供了理论依据,并找出了等强面积补强方法,对设计有实用价值。本课题主要进行了以下研究:①汽包常温内外壁电测试验,②在启.停及72小时试运行条件下的强度试验,③汽包集中下降管管接头三维光弹性试验研究.2 .7145 K31锅炉汽包焊接残余应力的试验研究(东方锅炉厂)采用盲孔法测定残余应力,并进行了误
(Dongfang Boiler Factory) Based on the assessment of steam drum strength of the first 300MW boiler in this plant, it provides a theoretical basis for the structure and material selection of the joint of the steam drum descending pipe and finds out Equal area reinforcement method, the design has practical value. The main research of this subject is as follows: (1) The inner and outer walls of the drum at room temperature electrical test, (2) the strength test under the conditions of start and stop and 72 hours of trial operation, (3) the drum to reduce the pipe joint 3D photoelasticity experiment.2. 7145 K31 Experimental study on welding residual stress of boiler drum (Dongfang Boiler Factory) The residual stress was measured by blind hole method and made a mistake
