针对甘肃省锅炉压力容器检验中对锅炉压力容器技术登录本中有关安全阀排汽量的校核计算 ,发现各电厂对安全阀排汽量的计算比较紊乱 ,校核计算结果误差已达 2 0～ 30 %。因此通过对一些锅炉、压力容器安全阀排汽量的典型计算 ,查明了计算中误差的原因是有的引用标准不合理 ,有些是计算公式的参数取用不当。提出在以后锅炉压力容器技术登录中 ,必须采用锅炉、压力容器所对应的标准所推荐的安全阀排汽量公式进行计算 ,才能有效解决目前在安全阀排汽量校核计算中的误差 ,确保锅炉压力容器的安全运行。
In the inspection of boiler pressure vessel in Gansu Province, the calculation and calculation of the amount of exhaust gas of safety valve was found in this paper. It was found that the calculation of the safety valve exhaust gas quantity in each power plant was disordered and the calculation error was 20 ~ 30%. Therefore, some boilers, pressure vessels safety valve exhaust calculation of a typical calculation to find the error in the calculation of the reasons are some of the reference standard is not reasonable, some of the parameters of the formula is not properly used. Proposed in the future boiler pressure vessel technology log, you must use the boiler, the pressure vessel corresponding to the standard recommended safety valve exhaust volume formula to calculate, in order to effectively solve the current safety valve exhaust gas check calculation error to ensure that Safe operation of boiler pressure vessels.
