How Do Fire Sprinklers Work?

Knowing about Fire Sprinkler Mechanism

Fire sprinklers are perceived as fancy devices that exist in almost all commercial spaces. These ideas are generally inspired by television, where a tiny fire or smoke triggers fire sprinklers into action. There is a popular misconception that any fire triggers fire sprinklers. Though both the terms sound very related, there is a mechanism that connects them. If the fire sprinklers would operate on a small fire, then even a cigarette could hold the potential to trigger the. This would waste gallons of water and instill fear in the minds of people as the sprinkler would start working very often. To avoid such instances, the manufacturers have devised fail-safe mechanisms for these fire sprinklers.

If you ask how to do fire sprinklers work, you are probably looking for answers that will make your life better. You are inevitably concerned with what might happen if you leave a fire unattended, but you cannot only look away and expect a fire to burn itself out in reality. When something is flammable, much damage can occur if the fire spreads too quickly. That is why it is essential to have a fire sprinkler system in place.

People tend to believe that fire sprinklers are best suited for commercial spaces, which again falls in the category of misconceptions. Out homes are equally vulnerable to catching fire, which makes fire sprinklers a mandatory component for any infrastructure.

When people inquire about how fire sprinklers work, they have many questions about what precisely a fire sprinkler system does. Fire sprinklers, or water sprinklers, are quite simple devices. They simply water a small area. It is the water that causes the sprinkler to spray out streams of water.

How Does a Fire Sprinkler Work?

The fire sprinkler system consists of a network of pipes that run inside the ceiling of the building. These pipes contain water at a high pressure, which immediately releases when the sprinkler turns on. A specially designed heat-sensitive plug is fitted in the water sprinkler, which activates with a rise in temperature. These plugs are generally of two types: an alloy that melts at a specific temperature or a glass bulb filled with glycerin-based liquid that expands and shatters with heat. Either way, the sprinkler’s opening allows the water to come out a specific temperature and bring down the heat in the surrounding.

Now, can these sprinklers be activated from the smoke of a burning toast or burning a piece of paper? No. These sprinklers are designed to operate at high temperatures. Glass bulbs for these sprinklers are available with different temperature ratings, generally more than 130⁰F. The color of the liquid inside these bulbs indicates the temperature rating of the lamp. The selection of these bulbs depends on the installation area and the probabilities of fire causalities in that area.

If you’re wondering how fire sprinklers work, it’s best to start by understanding how fire spreads. Fires are different from other fires in many ways. For example, when a light bulb burns out, the flame begins to smolder and cannot consume oxygen. Fire sprinklers work to accomplish this. These devices use water to dampen the flame before it can spread too quickly.

A fire sprinkler system usually consists of a tank that holds water, a sensor that activates the water, and the sprinkler head that sprays the water. There are two common types of fire sprinkler systems. One kind, known as the primary type, only has a nozzle and the tank. The other kind, commonly referred to as the dual-discharge type, uses a tank and two different nozzle heads.

How do fire sprinklers work in a basic sense? Water flows into the tank, which holds the water (usually a combination of groundwater and underground storage tank water). The water in the tank evaporates, leaving behind condensation, which helps create the moisture that the sprinkler head is made up of.

The water in the tank moves up the hose, goes through the sprinkler head, and into the air, causing the water to be sprayed out at the next fire location. There are many different fire sprinklers, such as horizontal nozzle sprinklers, vertical nozzle sprinklers, counterflow spray sprinklers, and cross-flow sprinklers.

The way fire sprinklers work, however, is not merely to evaporate water. They also use thermodynamics to keep flames from expanding to the point that they could cause significant damage.

If you’ve ever noticed that the fires you find on the news often show up in vacant houses, you may wonder how fire sprinklers work there. The problem is that there is not enough water pressure in a home to burn the fire out. This is where the use of thermodynamics comes in.

Fire sprinklers have two major parts. The first part is the tank, which is the part that holds the water and makes it evaporate, while the sprinkler head is the part that makes the water move around and spray it out.

In homes, most likely, the water supply comes from underground tanks. These tanks contain a large volume of water, and fire sprinklers need this water to work correctly.

In older homes, the water from the tanks is contaminated with fungi, mold, and bacteria that cause high humidity levels and can cause the fire to spread rapidly. In these cases, installing new tanks is one way to solve the problem.

What Is the Potential Impact and Benefit?

While fire sprinklers’ primary purpose is to douse the fire, they also serve as a medium to save on water and money. Principally, the fire sprinkler system is designed to activate one sprinkler head at a time. This one-by-one operation methodology saves a lot of water. Moreover, the water used by fire sprinklers in extinguishing the fire is way less than what is used by a fire hose. Sprinklers are gaining preference over other methods for even water distribution in their surroundings, which proves to be a highly effective method. Sprinklers are automated and require no assistance for operation. The entire framework of water pipelines is attached to a readily available, 24 hours operational water supply. The continuous water supply to fire sprinklers again acts in their favor, making them an ideal and fast rescue plan for any infrastructure. 

Climate-Based Methodology for Fire Sprinklers

Talking of the pipeline system of fire sprinklers, these sprinklers have a different operation mechanism in colder regions. A constant supply to the pipelines can end into the water freezing in them in frigid climates. This would ultimately rupture the pipes, causing more hazards than it can save. To avoid such situations, these pipelines are filled with compressed air rather than water. When the sprinkler heads activate in these systems, the gas leaks from the pipe, creating a pressure drop. This pressure allows the water to run through the pipes into the sprinklers heads to douse off the fire. Such systems are more often installed in unoccupied and unheated infrastructures as the temperature can steadily drop in the water pipes.

Major Considerations

To accommodate modern needs, these fire sprinklers have been evolved in time in terms of design and material. Special coatings of Teflon, polyester, and other materials are made on the sprinkler heads to protect them from corrosion and increase their life. 

Sprinkler systems are advised to be installed during any building construction to avoid unnecessary expenses on installing it after the space is operational. Besides money, an extended installation can cost you time and inconvenience. Spending on fire sprinklers can save you from the losses that can occur during fire accidents. Sprinklers are worthwhile investments as they can help you in finding an excellent insurance plan for your building. The insurers have different ideas for fire extinguisher-equipped spaces, thereby widening your insurance policy choices. A regular check on water sources’ availability is vital to keep the fire sprinklers operational and work at the time of need. Also, a periodic inspection for leaks in water pipelines is recommended to avoid unnecessary damage to the fire sprinklers system.
