This paper analyzes damage reason of electric heat tube of a midget electrically heated boiler by calculation of jet flow of return water pipe. The damage is a fatigue failure that is caused by direct acting of return water on electric heat tube. 通过对回水管的射流计算,分析了小型电热锅炉电热管损坏的原因:电热管的损坏是由于回水直接对电热管作用而引起的疲劳破坏。
