摘　　要：改革开放以来,随着我国经济的迅猛发展,对电力资源的需求愈加迫切,在今后相当长的一段时期,火力发电仍将在电力资源占有重要的主导地位。火力发电厂的燃料输煤系统成为保障电力正常供给的重要环节,其结构安全愈加重要。文中以哈尔滨某电厂建于不同年代的3个不同结构形式的输煤栈桥可靠性鉴定为例,依据相关规范对输煤栈桥结构可靠性鉴定,为类似工程检测鉴定提供宝贵经验。With the rapid development of China’s economy after reform and opening-up,the demand for power resources is more and more urgent for a quite long period of time,and the thermal power generation will still occupy an important leading position in the power resources.The fuel coal conveying system of thermal power plant has therefore become an important link to ensure the normal power supply in terms of its structural safety.In this paper,three coal conveyer trestles with different structure forms built in different ages in a power plant in Harbin is taken as the example,and the reliability evaluation of coal conveyer trestles is conducted according to relevant codes,providing valuable experience for similar engineering inspection and evaluation.
