Abstract

The paper contents the results of temperature and stress field calculations occurring in the cross-section of first tube of the platen superheater P3 in the boiler BP 1150 (steam capacity 1150t/h). The non-uniform heat flux distribution resulting from radiation (from flue gas in the superheater as well as from the furnace) and convection has been taken into account. Calculations have been carried out for two coals, with lower and higher heating value.
