During the generation of steam, most water impurities are not evaporated with the steam and thus concentrate in the boiler water. The concentration of the impurities is usually regulated by the blow down, which controls the amount of water (and concentrated impurities) purged from the steam drum. In a normal steam generator about 4% of hot water is wasted as blow down. This study has been undertaken for heat recovery with the help of shell and tube type heat exchanger to prevent heat losses in boiler blow down. The modeling of heat exchanger in CATIA V5 software which is having inner diameter 40 mm and outer diameter 80 mm. Here assembly of shell and tube are done with water and steam as medium. The process of simulation consists of meshing, solution method and results using CFD package ANSYS 16. The calculations for blow down heat losses are also done in this study.
