    The problem of stress in perforated thin-walled cylinders due to mechanical and thermal load was analyzed for cases where the load of the system varies both along the cylinder circumference and axially. Starting from the solution and considerations for a smooth thin-walled cylinder, the concept was expanded and the distribution of deformations caused by thermal loads on the cylinder and the resulting stresses in the structure of the thin-walled perforated cylinder was observed for a specific form of perforation. The cylindrical perforated burner is one of the main elements of premixed condensing boiler for home heating systems. The quality of combustion, and thus the heat load on the outer sheath of the burner, largely depends on the layout, shape and dimensions of the perforation. This paper presents the mechanical modeling of thermomechanical processes of a cylindrical gas burner with premixing for a triangular layout or the so-called checkerboard shape of perforation.
