The aim of this paper is to use numerical analysis and fine element method-FEM
to investigate the influence of furnace tube shape on the thermal strain of firetube boilers. Thermal stresses in corrugated furnace tubes of different shape, i.e.
with different corrugation pitch and depth, were analysed first. It was
demonstrated that the thermal stresses in corrugated furnace tube are
significantly reduced with the increase of corrugation depth. Than deformations
and stresses in the structure of a fire-tube boiler were analysed in a real
operating condition, for the cases of installed plain furnace tube and corrugated
furnace tubes with different shapes. It was concluded that in this fire-tube boiler,
which is of larger steam capacity, the corrugated furnace tube must be installed,
as well as that the maximal stress in the construction is reduced by the
installation of the furnace tube with greater corrugation depth. The analysis of
stresses due to pressure and thermal loads po...inted out that thermal stresses are
not lower-order stresses in comparison to stresses due to pressure loads, so they
must be taken into consideration for boiler strength analysis.
