本文对某炼油厂纯对流式加热炉新氢炉管的破裂问题进行了初步分析,认为此破裂是由H_2SO_4露点腐蚀造成,并估算了此炉管工作条件下的露点温度及露点腐蚀范围。为防止或减轻H_2SO_4露点腐蚀提出了某些建议。
In this paper, a preliminary analysis of the rupture of a new hydrogen furnace tube in a purely convection reheating furnace in a refinery was conducted. The rupture was caused by the dew point corrosion of H_2SO_4, and the dew point temperature and dew point corrosion range of the furnace tube were estimated. Some suggestions for preventing or reducing the dew point corrosion of H_2SO_4 are put forward.
