For heat exchange between steam and water, is it true that the higher the steam pressure, the better? Why?

The higher the steam pressure, the lower the latent heat. Depending on the purpose of using steam and water for heating, low-pressure steam is sufficient for heating water.

Looking at many of your questions, it seems like you’re acting like a child. This is a technical forum – what is technology? Technology is a capability that arises from the combination of knowledge and practice, and it is used to solve practical problems. Is your question a practical production issue? It seems like one of those \"Why?\" questions that children ask. Adults have their own ways of thinking and communicating; I hope you won’t keep asking questions in a childlike manner

Of course not. Once the steam pressure reaches a certain level, the thickness of the equipment increases, the requirements for welding and heat treatment rise, and the cost of the equipment doubles. Moreover, as steam pressure increases, the saturated vapor pressure also rises, and the temperature at which water turns into steam goes up as well. When the temperature reaches a certain level, the requirements for the materials used in the equipment become even higher.

A proposition with no constraints must be a false proposition; it’s obviously wrong, and one shouldn’t even need to think about it – this basic principle is not understood at all

What I actually want to ask is about the impact of high steam pressure on factors such as temperature differences, heat transfer, as well as the heat exchange area and efficiency of the heat exchanger. I’m sorry; perhaps you think this is a rather simple question.

The issue isn’t whether it’s simple or not. Technical problems arise from production and ultimately return to production. Asking questions in this way makes them at least logically more understandable. What does \"high vapor pressure\" mean? Does it refer to the pressure supplied by the factory being higher than what was designed, or is it the design value itself that has increased? These are two different aspects. When dealing with technical issues, one must base actions on reality; it is important to determine whether the solutions are based on actual phenomena or merely on assumptions with no real action taken. Don’t come up with random questions that confuse people. High steam pressure, high temperature, high heat energy, and a large temperature difference – these are common sense facts. The heat exchange area is an inherent parameter of the equipment; it remains unchanged once it has been determined.

Heat exchange between steam and water? I don’t know what your purpose is. Generally speaking, how is heat exchange achieved between steam and water? If water is used as the cooling medium to condense low-pressure steam (which is generally waste steam), then what pressure is needed for the steam? If steam is used to heat water, then the heat released by the steam comes mainly from phase change; isn’t it a waste to maintain such high steam pressure? Whether in terms of design or actual operation, I don’t think anyone would use high-pressure steam for heat exchange with water. You mentioned things like the area of the heat exchanger; in terms of design, the first step is to determine the heat exchange medium.

Hahahahahaha, it’s just a way to liven up the atmosphere – whoosh———, a basin of ice water poured down;P
