Abstract：In order to identify the accident related causes from high-temperature slurry burns which are likely to occur in slurry tank,by analyzing the operating features,combining the sizing technology,the fault tree of hightemperature slurry burns is built. It is able to find the various reasons and the logical relations behind the accidents and provide a liable basis for preventing future accidents of slurry burns. The new slurry tank structure which is designed by the results from the fault tree can improve greatly effectively prevent people from slurry burn accidents. Moreover,it will improve the safety performance of slurry tanks.
