confining prescribed fires

A Line of Nozzles that CAN confine an RxFire

Click here to see video of above

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. 

Manual valves on each hose segment can enable spray only where it is needed.   

 

confining an RxFire (prescribed fire)

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 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 in 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.



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 often limited in their water supplies. Therefore, I have designed a smaller version of the SprayNozzle 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 15 ft from adjacent nozzles and can be connected by 1.5 inch forest hose.







THE SMALLER NOZZLE BELOW IS FOR CONFINING RX FIRES

IT DELIVERS 5 GPM at 40 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.
