Problems with the steam drum in the synthesis tower
Thread Content
I’d like to ask about the principle of self-circulation in a drum… Please don’t explain it too simply; don’t just talk about pressure. It’s a circulation from top to bottom, and it would be good if there were calculations or some underlying principles involved
It uses a thermosiphon principle. The siphon effect is caused by the gravitational force between liquid molecules and the difference in potential energy; in other words, it utilizes the pressure difference in the water column to cause water to rise and then flow to lower areas. Since the water surface at each end of the pipe is under different atmospheric pressures, water flows from the side with higher pressure to the side with lower pressure, until the atmospheric pressures on both sides are equal and the water levels in the container become the same. At that point, the flow of water stops. The siphon effect can be used to quickly draw water out of a container
Don’t boost scores like this. Ugh, is this meant for everyone?
It is achieved through the difference in height and gravity
Reply to 4# zjabc: You don’t understand this; potential energy, gravitational potential energy… these are the concepts that need to be used to solve it with Bernoulli’s equation
Hehe, I don’t quite understand it. Then tell me?
Reply to 3# Learning from a master: Then can you tell me the principle behind it? I know the concept itself… but I’m not quite clear on the principle
It’s mainly due to the density difference – one side is water and the other side is a vapor-liquid mixture. Whether self-circulation can be achieved depends on the height of the steam drum as well as the pressure drop of the vapor-liquid mixture in the synthesis tower. The basic principle is still what the people above mentioned
