Tuletõrjekahurid

Tuletõrjekahurid, also known as fire cannons or deluge guns, are high-capacity water or foam dispensing devices used in firefighting. Their primary function is to deliver a large volume of extinguishing agent to a fire rapidly, often to control or extinguish industrial fires, petroleum fires, or large-scale incidents where conventional hose streams are insufficient. These devices can be fixed installations, such as those found in petrochemical plants, refineries, and storage facilities, or mobile units that can be deployed as needed.

The design of tuletõrjekahurid typically involves a large nozzle capable of producing a powerful stream or spray pattern. They are often powered by pressurized water or foam systems. The flow rates can be exceptionally high, measured in thousands of liters per minute, allowing for significant cooling and fire suppression. Some models are equipped with remote control capabilities, enabling firefighters to operate them from a safe distance, thereby reducing exposure to heat and hazardous conditions.

Tuletõrjekahurid are particularly effective against fuel fires due to their ability to apply large quantities of extinguishing agent over a wide area. They can also be used for cooling adjacent structures to prevent fire spread. The selection of a tuletõrjekahur depends on the specific fire hazard, the available water supply, and the desired reach and application rate. Regular maintenance and testing are crucial to ensure their operational readiness.
