The Smoothbore Nozzle
We are continuing our video series on nozzles with the Smoothbore. This nozzle remains a powerhouse in the American Fire Service. With the increase in heat release rates due to changes in products and materials our ability to throw serious water on the fire is of the utmost importance. The smoothbore nozzle offers several advantages for firefighters. Some of strongest advantages come with the simplistic design of the nozzle. The smoothbore has the ability to perform under extreme conditions with good flow at a low nozzle reaction. The nozzle is very difficult to clog with debris and if a hose line becomes kinked it will maintain fairly good flow compared to a high pressure fog nozzle (100 psi). Even though the fog/combination nozzle has the ability to absorb more heat energy at the same flow, the smoothbore has the ability to penetrate without steaming off when attacking the fire. Once the stream enters the room on fire we can bounce the stream off of walls and ceilings to break up the stream and increase its heat absorption capabilities. The video below will provide you with an overview of the smoothbore nozzle and will cover a few topics in detail.
