The safety valve in the stabilizer tower is liable to jump up when the operation parameters change greatly, especially during the startup.
主要原因是锅炉安全阀二次保护回路设计有缺陷，再加上安全阀起跳和回座的整定值与运行额定值相重叠造成的。
The main reasons were due to the defect in the design of safety valve secondary circuit and the overlap of the service rating and the setting for safety valve popping and reseating.
