Aiming at an organic heat carrier boiler medium leakage accident, the cause of the accident was discussed and analyzed by ifeld examining of the accident, crevasse macroscopic inspection, chemical composition analysis, metallographic analysis and medium laboratory analysis. The cause of this accident was considered as the operation of mismanagement, improper selection of auxiliary device, automatic control and protection device malfunction, resulting in serious overheating medium cracking and deteriorating, and the wall temperature of overheating, eventually leading to leakage accident. Combining with the work experience of boiler inspection, the suggestion and related measures for organic heat carrier boiler safety were put forward, which had the reference signiifcance to the safety management.
