| Abstract: | The biphenyl boiler's head with a large offset nozzle was analyzed using three dimensional finite element method. The stress intensity distributions along the longitudes of the nozzle and head in the symmetrical plane , and around the intersecting area all showed that stress concentration exists in a narrow area around the intersection. The strength evaluation for the connection was carried out according to the China Standard of design by analysis: JB4732, and the results showed that the strength of the structure meet the requirements for safety. |
