Industrial Wet Steam

Let’s recap quick: wet steam is the steam you usually see around your house and basically everywhere not investing seven to eight figure checks in their steam system. This wet-steam carries water vapor, which is the actual white, puffy cloud you see. Dry steam is essentially invisible, hot as fire, and essential in industrial scale productions. That begs the question though, is there an industry for wet steam too? Surely the dry-stuff is better? Moisturizing the Product It turns out, there are a ton of applications where it’s essential to add moisture to a product without actually soaking it. Consider, if you use dry steam, you’re not going to make the product wet, but you will dry it out. Between the heat and zero-humidity air, anything that can evaporate from the product will do so. Dry products presents a wide range of problems. Dry things are often inflexible and brittle. Consider if you leave a shirt in your clothes drier for  hours upon hours (do not do this, you’ll probably start a fire), if it survives, it’ll be rough, stiff, and uncomfortable. Dry steam works well enough for a quick cleaning of clothes, but it’s not good for prolonged exposure. This same thing is true in other types of production, consider something like a paper pill or a printing press. If the paper becomes too dry, it might tear inside the machinery. Excessively dry paper is prone to cracking, tearing, […]

What Is Dry Steam?

Despite being a centuries old technology, steam is still an essential part of the industrial world. There are a ton of special uses cases for steam in manufacturing, chemical processing, and elsewhere in heavy industry. We use steam for precise temperature control in specialized vacuum systems, for heating oil and fluids over long distances, for electrical turbines, to push fluids through piping such as in distillation towers, to improve burner efficiency, and for drying things. You Do WHAT?! It turns out that steam is actually incredibly useful for drying things, typically clothe things, but it’s been used on paints and other parts of product drying. You mean for WRINKLES in clothes and pants, right? NOPE. Alright, let’s break out the physics. This is actually something weird and incredibly interesting. Starting with the basics. Matter has essentially three states that you’re going to actually experience in day to day life: Solid, Liquid, and Gas. We all know what these look like, right? Solid water is ice. Liquid water is… well tap water, ocean water, lake water, rain. Gas-water is steam, a big, white, puffy, and usually burn-inducing cloud rising up from those noodles I boiled last night (and got the burn on my hand for). It turns out, we’re not entirely right about how we think of steam. That white, puffy cloud steam makes? It’s not a gas. It’s a liquid. If you physically see steam, the thing you’re seeing isn’t […]
