An RxFire (Prescribed Fire) is an intentionally set fire that is used to consume fuel on the ground so that a real wildfire will be stopped due to a lack of fuel.
The figure below shows how the spray hose system can be used to confine an RxFire. Only selected segments of the hose are enabled to spray. Manual valves on each hose segment can enable spray only where it is needed
The spray hose system can enable Rx Fires to be set when less than ideal weather and terrain would prevent starting an RxFire.
The image above shows more detail than the figure above it. The green main-hose is connected to the purple hoses by the white Valve Boxes which represent a manual valve. When a valve is opened, it causes a spray from its respective purple hose. This arrangement is being used to confine an RxFire by spraying only locations where spray is needed.
The Ball Valve allows the psi seen by the Rx Spray Nozzles to be varied by hand. The flow of water can be fine tuned to meet the needs of water vs. water conservation.
The yellow 2.5 inch hose can be the Trunk hose that supplies water to all of the 1.5 inch brown Spray Nozzle segments.
IT DELIVERS 5 GPM at 40 PSI.
I have been told that crews that set RxFires are often limited in their water supplies. Therefore, I have designed a smaller version of the
Spray Nozzle that uses less water to cover the same area as the original Spray Nozzle.
The figure below shows the smaller nozzle. It can be spaced 10 ft from adjacent nozzles and can be connected by 1.5 inch forestry hose.
