Mechanism for Wet Chemical Mist Nozzles to Suppress Kitchen Fires

Fire Extinguishing Suppression Mist Nozzles For Commercial Kitchen

The water mist fire suppression nozzle are kinds of extinguishing agent added mist nozzles or water based mist nozzles, also open type intermediate pressure water mist nozzles. The extinguishing agent would be potassium carbonate based or similar water based extinguishing agent that specifically designed to extinguish grease laden fires such as those found in commercial cooking areas.
Usually these water mist fire suppression nozzle are with single orifices to provide proper coverage to targets, i.e., the appliances and cooking tools.

Design Features

Specially designed for wet chemical spray to suppress Kitchen fires (Class K / Class F fire);
Fine mist produced at intermediate pressures for rapidly cooling and re-ignition preventing;
Big spray momentum to penetrate the fire;
Different flow rates and coverage available;
Protective nozzle caps for preventing from logging problem by grease.
 

Spray Characteristics

● Spray pattern: Full cone
● Operating pressure: 10-30 bar
● Spray angles: 45-90 degrees
● Flow rates: 5L/min-12L/min

The mist nozzles suppress a fire in three ways:

1. The agent sprayed interrupts the chemical chain reaction causing combustion, thus extinguishing the fire.
2. The agent is discharged by mist nozzles in very fine droplets, cooling the fire to below its auto-ignition temperature.
3. The agent reacts with grease to form a foam-like layer commonly called saponification that starves the fire of oxygen, stopping combustion and preventing re-ignition.

This water mist fire suppression nozzles are tailor made to achieve the best performance for different appliances and extinguishing agent. Some parts of our standard mist nozzles would be replacement as nozzles in premier Brands of kitchen fire suppression systems, such as Ansul, Amerex, Buckeye, etc.

The tiny water droplets produced by fine water mist fire extinguishing nozzle have a large specific surface area and can rapidly absorb heat and convert it into water vapor, which rapidly reduces the temperature near the ignition point and isolates oxygen and other combustible gases, so that it is difficult to maintain combustion and gradually extinguish oxygen to achieve the purpose of fire extinguishing.
 
Although water mist fire suppression nozzle takes water as fire extinguishing medium, it is in the form of water mist fire suppression, which has the basic attribute of gas fire extinguishing.
 

Characteristics of water mist nozzle for fire extinguishing system

1. Safety and environmental protection -- physical fire extinguishing with water as fire extinguishing agent, without damage or pollution to the environment, protected objects and people in the reserve.
 
2. Efficient fire suppression - cooling rate is 100 times faster than normal sprinkler system. fire suppression fine water mist nozzle also has penetration, can solve the problem of total submersion and shelter, but also can prevent the recurrence of fire.
 
3. Purification effect - fire suppression water mist nozzle can purify smoke and exhaust gas, is conducive to the safety of evacuation and fire fighting personnel rescue work.
 
4. Shielding radiant heat - fire extinguishing water mist nozzle has a good shielding effect on thermal radiation, so as to prevent the spread of fire and quickly control the fire.
 
5. Small water loss - water consumption is only 1-5% of the water misting nozzle for fire suppression system, avoiding a large amount of drainage damage to equipment and secondary pollution to the environment.
 
6. Good electrical insulation - fire extinguishing water mist nozzle spraying can effectively fight live equipment fire.
 
7. High reliability - after the fire extinguishing fine water mist nozzle is installed, it can be simulated to check the system to increase the reliability of the system action.
 
8. Long system life - pumps, valves and fittings are made of corrosion-resistant materials and system life can be up to 30 (60) years.
 
9. Flexible preparation - fire suppression water mist nozzle can be used locally to protect a separate facility or part of a facility; As a fully submerged system, it protects the entire space.
 
10. Simple installation - compared with traditional fire extinguishing system, the pipe diameter is small, only 10-32mm, so that the installation cost is correspondingly reduced.
 
11. Easy maintenance - only water as fire extinguishing agent, in the standby state of atmospheric pressure, daily maintenance workload and cost greatly reduced.
