This is due to the fact that by reducing the amount of I of steam along its course through pipe W by condensing part of the steam at the same time (the forward section on the steam side decreases.

“, R.srjjl pipe 9 - for the removal of steam condensate. The coils are connected in pairs to vertical dispensing manifolds 10 and collecting manifolds 11. A pipe 12 is fed to remove non-condensable gases in the central part of housing 1. Steam enters the coils through the nozzle b to the coil 3. The size of the mesed clearance by the outer planes of the 5 coils provides steam access to the whole heat exchange surface of the latter. As a result of this, a concurrent flow of condensing condensate and a film of condensate occurs along the lower coils of pipe coils. The type of inclination of the coils is chosen so as to provide a continuous and non-contact movement of codensate film with downstream spirals. In the lower parts of the pipe coils, the condensate film is torn off and is carried out by inertia along the spacer of the star bar 4 beyond the coil 3, thereby preventing the latter from being flooded by the condesate. All of this increases the efficiency of the coobmoyo.
