Fire presents a significant and ever-present danger in power plants of all types. Regardless of whether you are dealing with a fossil fuel, nuclear, or hydro plant, it is essential to have the right kind of fire protection in place. Depending on the area of the plant in question, fire protection systems for power plants may incorporate a number of tactics, including both passive (building features such as firewalls) and active (suppression) fire protection measures.
Seawater is often used as a fire protection fluid, both in offshore applications and for on-shore sites located close to the ocean, due to its ready availability and low cost. However, seawater does present challenges due to its corrosive nature.
Industrial fire protection valves are designed to be robust, but even the toughest valve body can crack or break when subjected to the pressure exerted upon it from inside by the expansion of water as it freezes. In environments where freezing temperatures are likely or even possible, it is important to protect your deluge valves from this possibility. A number of solutions exist to protect deluge valves from freezing. Let’s explore the pros and cons of each.
Deluge valves are a critical part of many industrial fire protection systems, and often referred to as ''the heart of the system'', as they take a major role in protecting life and property.
A fire event can cause untold damage to property. But sometimes the extinguishing water can do as much damage to protected items as the fire itself. This includes such places as computer rooms, film archives, museums and other moisture-sensitive areas. In such areas where a false alarm can be catastrophic and the deployment of water should be restricted to the fire area alone, rather than the whole building or room, it can make sense to use a preaction fire protection system.
There are many ways to put out a fire. Depending on the situation, a fire protection system can be designed to work with various fire suppression agents. Plain water is commonly used because it is easily available and effective in many cases. However, water is not always the best choice. Other options include inert gases, dry or wet chemical agents, and different types of fire suppressing foam. In this post, we will discuss foam applications.
One of the many choices to be made in designing an industrial fire protection system is to determine the deluge valves operation philosophy in the event of a fire - manually or automatically. The next designing step for an automatic operation is how the pilot sprinklers with fusible plugs will be activated, pneumatically or hydraulically. The advantage of an automatic operation is that it takes place immediately in response to triggering conditions such as heat or flame, without need for human interference or decision making. This enables fast system response even in remote or unmanned locations.
When selecting a deluge valve for your fire protection system, one of the most important things to consider is flow capacity with low head loss. In a fire protection situation, every second is critical. It is essential for water/foam to reach the fire as soon as possible after the detection system is activated . Even a short delay can be catastrophic, especially where flammable materials are present. A valve’s specific design will affect both the volume and speed with which fluid can pass through the unit. These in turn have a significant effect on system performance, and on the eventual outcome should a fire event occur.

They say knowledge is power. And that is certainly true in fire protection. Knowing exactly what is going on in your fire protection system at any given time gives you vastly greater control. Reliable indication of the state of a valve can help diagnose problems, reduce system maintenance time, and improve performance and response time during a fire event.

The Sakhalin project is a two-phase, on- and off-shore oil and gas development on Sakhalin Island, Russia, located in the Okhotsk Sea. The project is owned and operated by Exxon Neftegas Limited (ENL). Combined, the Sakhalin phase 1 and 2 reserves contain an estimated 1,200 million barrels of crude oil. The project includes Russia’s first LNG plant, and is expected to contribute billions of dollars to the Russian economy. The first Sakhalin 1 well was drilled in 2003.
