Hey there! I'm a supplier of Deoxygenation Towers, and I'm super stoked to share with you how these nifty pieces of equipment work in a power plant. So, let's dive right in!
The Basics of a Power Plant and the Need for Deoxygenation
First off, let's talk a bit about power plants. Most power plants, especially those that generate electricity through steam turbines, rely on water as a crucial working fluid. Water is heated to produce steam, which then drives the turbines to generate electricity. But here's the catch - the water used in these systems can contain dissolved gases, mainly oxygen and carbon dioxide.
These dissolved gases are a big no - no in power plant systems. Oxygen, in particular, is highly corrosive. When it comes into contact with the metal components of the power plant, like pipes, boilers, and turbines, it can cause oxidation and corrosion. This not only shortens the lifespan of these expensive components but also reduces the efficiency of the power plant and can even lead to dangerous situations. That's where the Deoxygenation Tower steps in.
How a Deoxygenation Tower Works
A Deoxygenation Tower is designed to remove these dissolved gases from the water before it enters the boiler or other critical parts of the power plant. There are two main types of deoxygenation processes: thermal deoxygenation and chemical deoxygenation. In most power plants, thermal deoxygenation is the primary method, and that's what we'll focus on here.
1. Pre - Heating the Water
The process starts with pre - heating the water. The incoming water is usually at a relatively low temperature, and it needs to be heated up to a specific level. This pre - heating is often done using steam extracted from the turbine. The pre - heated water then enters the top of the Deoxygenation Tower.
2. Spray Nozzles and Droplet Formation
Once inside the tower, the water passes through a series of spray nozzles. These nozzles break the water into tiny droplets. The reason for this is simple - by increasing the surface area of the water, we can speed up the process of gas removal. The larger the surface area, the easier it is for the dissolved gases to escape from the water.
3. Counter - Current Steam Flow
As the water droplets fall through the tower, they encounter a counter - current flow of steam. The steam is introduced at the bottom of the tower and rises upwards. This steam is usually at a high temperature and low pressure. The high temperature of the steam helps to drive the dissolved gases out of the water. According to Henry's Law, the solubility of a gas in a liquid decreases as the temperature increases. So, as the hot steam comes into contact with the water droplets, the oxygen and carbon dioxide are forced out of the water.
4. Stripping the Gases
The counter - current steam flow also acts as a stripping agent. It carries the released gases away from the water. The steam and the released gases then exit the top of the Deoxygenation Tower. This mixture is often sent to a condenser, where the steam is condensed back into water, and the gases are vented to the atmosphere.
5. Collecting the Deoxygenated Water
The deoxygenated water collects at the bottom of the tower. It is then pumped to the boiler or other parts of the power plant where it will be used to generate steam. Before it leaves the tower, it's common to add a small amount of a chemical oxygen scavenger to ensure that any remaining traces of oxygen are removed.

Other Types of Towers in Power Plants
In addition to Deoxygenation Towers, there are other types of towers that play important roles in power plants. For example, the Fractionation Tower is used to separate different components of a mixture based on their boiling points. This is often used in the refining process of fuels used in power plants.
The Gas Drying Tower is another important piece of equipment. It is used to remove moisture from gases, which is crucial for the proper functioning of gas - fired power plants.
And then there's the Drying Tower, which can be used to dry various materials used in the power plant, such as coal or other solid fuels.
