| Abstract: | The classical method for calculating wall temperature of heating surface has been improved and perfected, and applicable software being worked out on this basis. The causes of frequent tubeburst due to overtemperature of the hightemperature superheater for a 620t/h boiler being calculated and analysed, and simple and effective retrofitting scheme being put forward. After retrofitting, tubeburst of hightemperature superheater due to overtemperature has not occurred again, ensuring safe and economic operation of the unit. Test data and operation results show that the calculation method and calculated results after retrofitting to be accurate and reliable, having value for popularizing its application. |
