The hull of a condenser as refrigerant materials and materials has natural draft or in comprising applications

摘要

The shell is intended for a tower cooler for a thermal power station having exchange surfaces 11 located inside the cooler. The vertical profile of the shell is such that the hydraulic diameter in each horizontal section, at a height z above a reference section where the hydraulic diameter is D0, has a value of between one and 1.15 times the value given by the formula : IMAGE in which : V0 is the vertical delivery speed in the reference section; rho is the density of the hot air; DELTA is the difference in density between the hot air inside and that outside the shell; epsilon is a dimensionless adjustment parameter having a value of between 0.09 and 0.13.
