2.Principal Applications for Steam

12/09/2023

Steam is used in a wide range of industries. Common applications for steam are, for example, steam heated processes in plants and factories and steam driven turbines in electric power plants, but the uses of steam in industry extend far beyond this. Here are some typical applications for steam in industry: Heating/Sterilization Propulsion/Drive Motive Atomization Cleaning Moisturization Humidification In the sections that follow, we will discuss various types of applications for steam, and provide some examples of steam-using equipment to illustrate them.

3.Types of Steam

12/09/2023

If water is heated beyond the boiling point, it vaporizes into steam, or water in the gaseous state. However, not all steam is the same. The properties of steam vary greatly depending on the pressure and temperature to which it is subject. In the article Principal Applications for Steam, we discussed several applications in which steam is used. In the sections that follow, we will discuss the types of steam used in these applications.

4.Clean & Pure Steam

12/09/2023

Have you considered the quality of your steam? In the production of certain goods such as food, electronics, and pharmaceutical products, a higher degree of steam quality is vital. In order to meet these needs, it would be ideal to use steam that is devoid of condensate, debris, and any other impurities (or almost so). The goal in producing filtered, clean, or pure steam is to get as close to the ideal state for each specific application as possible.

5.Heating with Steam

12/09/2023

Steam is one of the most common and effective heat transfer mediums used in industry, but it is not the only medium available. Other fluids such as hot water and oil are also used for indirect heating in heat exchangers. The following series of articles will focus on the advantages of using steam compared to hot water or oil for heating.

6.Overall Heat Transfer Coefficient

20/09/2023

The overall heat transfer coefficient, or U-value, refers to how well heat is conducted through over a series of resistant mediums. Its units are the W/(m2°C) [Btu/(hr-ft2°F)].

7.Steam Heating Mechanism

20/09/2023

In this article, we will first take a look at how steam provides even and rapid heating. This will be followed by a discussion about the heat transfer rate supported by experimental data comparing hot water and steam.

8.How to Read a Steam Table

20/09/2023

Just as a map (or GPS navigation system) is necessary when driving in a new area or a flight timetable is indispensable when taking the plane, steam tables are essential to steam users in industry. This article will introduce steam tables, pointing out the different types and offering an overview of the different elements found within them.

9.Wet Steam vs. Dry Steam: The Importance of the Steam Dryness Fraction

20/09/2023

Did you know that boilers do not generate 100% saturated steam (dry steam)? When a steam boiler heats up water, bubbles breaking through the water surface will pull tiny water droplets in with the steam. Unless a superheater is used, this will cause the steam supply to become partially wet (wet steam) from the added liquid.

10.Temperature Problems Caused by Air

20/09/2023

Is the supply steam to your process at the correct pressure, but for some reason under-temperature? Does the product fail to heat up to the correct temperature? Air can diffuse and mix with steam at start-up or during regular operation, which effectively reduces the steam pressure and results in reduced heat transfer. This phenomenon can be explained by Dalton's Law of Partial Pressures.

11.Removing Air from Steam Equipment

20/09/2023

As seen in the article discussing Temperature Problems Caused by Air, removing air from steam equipment is essential to effectively use steam. The following article will first cover the relationship between the densities of air and steam, and then discuss how this affects the positioning of air vents in steam-using equipment.

12.Air Vents for Steam

20/09/2023

In the article Removing Air from Steam Equipment, discussion mostly revolved around the density of air and steam, as well as how system configuration can influence the position of air vents. The following article will focus on balanced pressure air vents for steam systems.

13.Is My Trap Leaking Live Steam?

20/09/2023

Have you ever wondered about the vapor clouds seen at the outlet of steam traps? These wisps of vapor can be either live steam or simply flash steam. This article aims to deepen understanding of the subtle difference between the two.
