The role of kitchen high-temperature nozzles

In modern society, the kitchen is the life center of every household and the place where food is cooked. However, the kitchen is also one of the most fire-prone areas, as cooking activities are often accompanied by flames, high temperatures and flammable substances.

In order to guarantee the safety of people’s lives and property, the application of fire protection systems in kitchens is particularly important, in which high-temperature nozzles, an essential component, play a vital role.
This paper will discuss the role of high temperature nozzles in kitchen deeply, including their principles, mechanisms of operation, classifications, and their importance in fire response.


Principles and mechanism of high-temperature nozzle


The high temperature nozzle is specifically designed for applications in kitchens. Its principle is based on the characteristics of fire, especially in the presence of high temperatures, flames and flammable substances.
High temperature nozzles include a sensitive temperature sensor, usually set at about 150 °C. Once the temperature exceeds the set threshold, the sensor triggers the high temperature nozzle to spray extinguishing agent (such as water, foam or dry powder) at high pressure onto the fire source.

Working mechanisms

The mechanism of the high temperature nozzle is simple but efficient. When the temperature inside the kitchen rises to a trigger point, a temperature sensor will detect the change.
Once the trigger point is reached, the high-temperature nozzle will activate immediately and release the extinguishing agent in the direction of the fire source. This process is automatic and allows for a quick response in the event of a fire to minimize the damage caused by the fire.
High-temperature nozzles usually spray the extinguishing agent evenly over the fire source in order to extinguish the fire as quickly as possible. These nozzles are often designed as micro-atomizers that spray the extinguishing agent into tiny particles to provide a larger coverage area and effectively reduce the temperature of the fire source.

Classifications of high-temperature nozzles

High-temperature spray nozzles can be categorized differently in terms of design and application, and the specific categorization can be defined according to the application, the spraying medium and the spraying method.

Spraying medium

1. Water nozzles: water is a common fire extinguishing agent for a wide range of kitchen fires. Water nozzles are usually the most common type of high-temperature nozzle and can quickly cool a fire source to extinguish it effectively.
2. Foam nozzles: usually used for grease fires, as the foam can form an isolation barrier on the surface of the fire source, which prevents the flame from spreading.
3. Dry powder nozzles: suitable for many types of fires as the dry powder blocks the supply of oxygen, including liquid and solid fires.

Spraying method

1. Jet high temperature nozzles: spraying extinguishing agent onto the fire source at high speed, it can effectively cool the fire source and extinguish the fire. It is suitable for cases that require a quick response.
2. Atomizing high-temperature nozzles: atomize the extinguishing agent into tiny particles, which increases the coverage area and can reduce the temperature of the fire source more effectively.
3. Rotating high temperature nozzles: designed with a rotating nozzle to cover a wider area to extinguish the fire, which is particularly useful for large kitchens or situations where more area needs to be covered.

The role of high-temperature spray nozzles

Preventing fires

The primary role is to prevent fires. In most cases, fires are caused by careless handling during the cooking process. The automatic triggering mechanism of the high temperature nozzles deals with these problems quickly, and extinguishing the source of the fire before it spreads, thus preventing fires from occurring.

Increasing escape time

High-temperature nozzles can also play an important role during a fire. Their rapid response capability not only controls the fire, but also reduces the temperature around the fire, which provides more time for people trapped near the fire to escape, increasing their chances of survival.

Protecting properties

Fire is not only a threat to life, it can also cause property damage, including damaged appliances, cooking equipment, and the building itself. The rapid response of a high temperature nozzle can minimize fire damage to these properties, thus reducing repair and replacement costs.

Reducing the spread of fire

The rapid spread of fire is a common problem, especially in small spaces like kitchens. The use of high temperature nozzles can effectively curb the spread of a fire so that it doesn’t spread to other areas, which reduces the scale of the fire.

Installation and maintenance of high-temperature nozzles


A professional is needed to select the appropriate model and location based on the specific needs and layout of the kitchen.
High temperature nozzles are usually installed in the ceiling to ensure that the entire kitchen area can be covered.


High temperature nozzles require regular maintenance to ensure they work properly.
The maintenance includes:
1. Check temperature sensors and mechanical components regularly to ensure proper operation.
2. Clean the nozzles to prevent clogging.
3. Test the high-temperature nozzles periodically to ensure that the triggering mechanism is working correctly.
4. Monitor the operating status of the nozzles at any time to ensure that they are able to respond quickly in a fire situation.


High temperature nozzles play a vital role in kitchen fires, they provide a safeguard for people in the kitchen. When designing and maintaining a fire protection system in a kitchen, high temperature nozzles should be fully considered and their normal operation should be guaranteed to ensure the safety and sustainability of the kitchen.
By understanding the principles, working mechanisms and other aspects of high-temperature nozzles, people can better understand their importance in fire response and better protect themselves and their families from the threat of kitchen fires.
In the end, high-temperature nozzles are a critical piece of technology that brings an extra barrier of safety and improves the quality of our lives.
