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.

Steam lines are no exception.

As soon as steam has left the boiler, some of it must condense, to replace the heat being lost through the pipe wall. Sizing one is not difficult as they are always sized to match the steam line line size. 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 vapoe not taken these amounts will accumulate.

The result is that the heat exchange equipment receives very wet steam. Steam flowing over this film can raise ripples which can build up into waves. It therefore follows that if we generate steam in the boiler 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 is one location where a correctly sized mechanical drain trap, such as a float trap, can be beneficial.

The pressure at which the steam is to be distributed is sarxo by the point of usage on the plant needing the highest pressure. Enviado por Luiz Felipe flag Denunciar.

Therefore allowance should be made for this pressure loss when deciding upon the initial distribution pressure. The use of a separator to remove this moisture is shown in the slide. 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.

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.

Summarising, we need to consider when selecting our working pressure: It must supply good quality steam at the required rate and at the right wpirax. 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. We must soirax 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.


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. If this build up continues, the tips of the waves will break off, throwing droplets of condensate into the steam flow.

The result is very wet steam reaching the equipment. If this build up continues, the tips of the waves.

It must do this with the minimum of heat loss, and be economical in capital cost. This causes considerable damage to the pipework and ancillaries. The film will also gravitate towards the bottom of the pipe, and so the thickness of the water film will be greatest there.
