There it displaces air by evacuation through the radiator vent valves condenses on the radiators inner surface and gives up heat.
Steam in a heating system flows through.
Circular aluminum alloy 2024 t6 fins k 186 w m k of outer diameter 6 cm and constant thickness 1 mm are attached to the tube the space between the fins is 3 mm and thus there are 250 fins per meter length of the tube.
Steam in a heating system flows through tubes whoseouter diameter is 3 cm and whose walls are maintained at a temperature of 120t.

Steam condensate flows by gravity back through the same pipes to the boiler for reheating.
Steam in a heating system flows through tubes whose outer diameter is d 1 3 cm and whose walls are maintained at a temperature of 125 o c.
P17 i22 the space between the fins is 3 mm and thus there are 200 fins per meter length of the tube.
Saturated steam flow through a control valve.
The radiators and steam supply pipes are pitched so that gravity eventually takes this condensate back down through the steam supply piping to the boiler where it can once again be turned into steam and returned to the.
Change a product or fluid temperature.
Circular aluminium fins k 180 w m o c of outer diameter d 2 6 cm and constant thickness t 2mm are attached to the tube as shown in the figure.
Steam in a heating system flows through tubes whose outer diameter is 5 cm and whose walls maintained at a temperature of 180 degree c.
Circular aluminum alkiy 2024 t6 fins k 186 w m.
Maintain a product or fluid temperature.
The space between the fins is 3 mm and thus there are 200 fins per meter length of the tube.
In the oldest modern hydronic heating technology a single pipe steam system delivers steam to the radiators where the steam gives up its heat and is condensed back to water.
The energy released when steam condenses to water is in the range 2000 2250 kj kg depending on the pressure compared to water with 80 120 kj kg with temperature difference 20 30 o c.
