The use of a separator to remove this moisture is shown in the slide. It therefore follows that if we generate steam in the spirx at a much higher pressure than that needed by its application, and we distribute it at this higher pressure the bore of the distribution mains will be smaller for any given mass flow rate.

This causes considerable damage to the pipework and ancillaries. Steam lines are no exception.

Therefore allowance should be made for this pressure loss when deciding upon the initial distribution pressure. If this build up continues, the tips of the waves will break off, throwing droplets of condensate into the steam flow.

As soon as steam has left the boiler, some of it must condense, to replace the heat being lost through the pipe wall. The pressure at which the steam is to be distributed is determined vvapor the point of usage on the plant needing the highest pressure.

The condensate will form droplets on the inside of the pipe wall, and these can merge into a film as they are swept along by the steam flow.

Sizing one is not difficult as they are always sized to match the steam line line size. It must supply good quality steam at the required rate and at the right pressure. Enviado por Luiz Felipe flag Denunciar. Pressure required at point of use Pressure drop along pipe due to resistance of flow friction Pipe heat losses We also know that steam at a higher pressure occupies less volume per kg. If taken from the side, or even worse from the bottom, they can carry the condensate from the main and in effect become a drain pocket.

Steam flowing over this film can raise ripples which can build up into waves. The result is very wet steam reaching the equipment. We must remember however that as the steam passes through the distribution pipework, it will lose some of its pressure due to resistance to flow, and the fact that some of it will condense due to loss of heat from the pipes. Steam leaving a boiler, or other sources, is often much wetter than is appreciated and if this water is not removed, there will be poor heat transfer at the point of use this is why the steam needs to be dry.

If this build up continues, the tips of the waves. The film will also gravitate towards the bottom of the pipe, and so the thickness of the water film will be greatest there.

Summarising, we need to consider when selecting our working pressure: It must do this with the minimum of heat loss, and be economical df capital cost. Insulation will naturally reduce the heat loss, but the heat flow and the condensation rate remain as small but finite amounts and if appropriate action is not taken these amounts will accumulate.

We already know that dry saturated steam not superheated is to be used for process and heating applications and it is that with which we shall concern ourselves. This is one location where a correctly sized mechanical drain trap, such as a float trap, can be beneficial. The result is that the heat exchange equipment receives very wet steam.
