Abstract
Harmonization of environmental protection and the growing energy needs of modern society promote the biomass application as a replacement for fossil fuels and a viable option to mitigate the greenhouse gas emissions. For domestic conditions this is particularly important as more than 60% of renewable belongs to biomass. Beside numerous benefits of using biomass for energy purposes, there are certain drawbacks, one of which is a possible high emission of NOx during the combustion of these fuels. Thermal stresses in corrugated furnace tubes of different shape, i.e. with different corrugation pitch and depth, were analyzed 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 analyzed in a real operating condition, for the cases of installed plain furnace tube and corrugated furnace tubes with different shapes. So if we place furnace outside the boiler then less thermal stress are acting on furnace because of furnace contact with atmospheric gasses. And also ash handling is easier in this case.
