Help with steam condensate pipe piping problems behind the trap
Thread Content
There are several steam heaters placed at an altitude of 16 meters, with 6 kilograms of steam. The heater steam condensate outlet pipe is at an altitude of 16.3 meters. Several groups of condensate pipes are collected at an altitude of 19 meters and then discharged to the ground at an altitude of 1 meter. Please give me some advice.: Are there any problems with this piping method? Will the condensed water at an altitude of 19 meters flow back into the heater, causing poor heat exchange effect? See attached picture
I have no similar experience, but I personally think it should be no problem. Because the driving force of condensate water should be the difference between the steam pipe network pressure and the return pipe pressure. There is also a water trap that has a certain relationship with the working condition. But usually there is no problem. This is just my personal understanding and is not misleading.
The switch of the trap seems to be controlled by the liquid level. When the liquid level is high, the trap opens and drains water; when the liquid level is low, it closes and does not drain water. When draining, there is a pressure of 6 kilograms (60 meters) inside the trap and a pressure of 3 meters outside, so there should be no backflow. I don’t know if it’s right or not.
The steam side has a higher pressure, otherwise the heat exchange effect will not be achieved, so there will be no problem of the condensate from the trap flowing back to the heat exchanger and affecting the heat exchange effect. The pressure of the steam is enough to transport the condensate to the condensate collection tank.
No problem, the installation method is the same as the drainage of the steam pipe network.
I would like to ask, if there is still uncondensed steam in the pipeline, will there be a steam blockage?
As long as the steam pressure exists, there is no problem if it can overcome 19m!
Don't look at it as 19 meters, the water pressure in the pipe is only 3 meters. Don't worry, 6 kilograms vs. 0.3 kilograms. As long as there is pressure in the steam pipe, there will be no problem.
