Photo shows Thinning and Rxfire are best protection

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 Ethernet spray hose system  can be used to confine an RxFire. Only a selected segment of the hose is enabled to spray.  

The spray hose system can enable Rx Fires to be set when less than ideal weather and terrain would prevent starting an RxFire.    

A lower cost version of this system would NOT use a digital network to control the segment spray enable valves. The valve control would be done MANUALLY by firefighters.

Segmented Spray hose

 The image above shows  more detail than the figure at the top of the page. The green main-hose is connected to the purple hoses by the white  Valve Boxes which contain an electric or 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 in locations where spray is needed.


Very low cost version of the valve box shown in previous photo

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.

Spray Nozzles that deliver less water with same coverage

Confining RxFires with Less Water

I have been told that crews that set RxFires are usually limited in their water supplies. Therefore, I have designed a version of the SprayNozzle that uses less water to cover the same area as the original Spray Nozzle.


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 control, while conserving water.





THE SMALLER NOZZLE BELOW IS FOR CONFINING RX FIRES

IT DELIVERS 4 GPM @ 100 PSI 

Confining RxFires will not need as much water as protecting a home. 

Will be very low cost. Just 3 pieces of PVc.

Below: Two low cost clamps are used to hold the nozzle at the desired angle.

The 10 nozzle array is a perfect match for  MARK 3 pump.

The video below shows 10 nozzles that are 10 feet apart.

They are connected by 1.5 inch fire hose.
