Heat transfer and thermal deformation analysis
of boiler heat exchanger

2. Overview
The objective of this study is to assess the
performance of the heat exchanger inside the
boiler, and investigate the effect on the shape
of the boiler due to thermal stresses.
Following analysis types were
used in the study:
• Material nonlinear analysis
• Nonlinear analysis
• Geometry nonlinear analysis
