The peculiarities of using nanofluids as working fluids in fire tube boilers

The paper deals with addressing the issues pertaining to the heat exchange enhancement from the organic working fluid when using nanoparticles. The mathematical dependences of the fire-tube boiler thermal calculation are proposed. According to the calculation data, the graphical dependences of the heat transfer coefficients between the working fluid and furnace, metal structures temperatures, of the convective pipes and convective surface area heat transfer coefficient on the nanoparticles concentration were obtained.
