What is a kitchen cooking equipment automatic fire extinguishing system? How does it differ from previous kitchen fire extinguishing systems?

Previous kitchen fire protection systems referred to the fire protection systems designed for the kitchen buildings themselves, commonly including smoke and heat detection systems, as well as water sprinkler systems. Due to the fact that kitchen fires often result from uncontrolled cooking fires on the stove, igniting the oil residue in the canopy and exhaust ducts, leading to uncontrollable towering fires, the hot cooking equipment in the kitchen (stoves, canopy, exhaust ducts) has become the protected objects within the kitchen. The systems that provide localized fire protection for kitchen hot cooking equipment are known as kitchen cooking equipment automatic fire extinguishing systems. These systems are two independent fire protection systems with different protected objects, and they do not interfere with each other.

Why install an automatic fire suppression system for kitchen cooking equipment with a chimney fire suppression feature?

Due to kitchen fires typically involving the combustion of high flash point (315-450 degrees) cooking oils, their characteristics include rapid spread, high heat capacity, and strong concealment in ducts, making extinguishing them difficult. Thus, quickly extinguishing the flames is one of the challenges in combating kitchen fires, suppressing reignition is another, and preventing the spread of duct fires is the third.

What types of locations are suitable for kitchen cooking equipment automatic fire extinguishing systems?

Kitchen conditions in public buildings such as hotels, restaurants, dining halls, government agencies, schools, and corporate entities must meet the following standards:
