Advantages (?) Of Regulator Valved Stoves, Purpose I

UPDATE 10 FEB 2013:  Advantages (?) of Regulator Valved Stoves, Part II is straightaway available.


INTRODUCTION
Soto Outdoors late introduced their OD-1R Micro-Regulator stove.  Soto created a skilful bargain of buzz when they posted the next video which makes it hold back every bit though a regulator valved stove has quite an wages over a conventional needle valved stove.  The relevant segment starts at 1:03.


What advantages, if any, exercise regulator valved stoves offer?

This post service is Part I of Advantages (?) of Regulator Valved Stoves, an investigation into the advantages, if any, of stoves that convey a regulator valve.

Part II tin live seen here:  Advantages (?) of Regulator Valved Stoves, Part II

Several people convey mentioned inwards passing that their canisters were to a greater extent than fully drained subsequently using a regulator valved stove than when using a conventional needle valved stove.  In addition, inwards a tidings amongst an private who has worked a skilful bargain amongst LPG commercially, said private felt that a regulator valve would purpose at lower gas pressures (such every bit those inwards a seemingly exhausted canister) than a needle valve.  If inwards fact a regulator valved stove were to brand to a greater extent than amount usage of the gas carried when backpacking, this to a greater extent than amount usage would live of value to backpackers.  I fix out to acquit a unproblematic experiment to meet if indeed a regulator valved stove mightiness brand to a greater extent than amount usage of the gas inwards a canister.  My experiment would exhaust a canister using a needle valved stove together with and then supersede the needle valved stove amongst a regulator valved stove to meet if the regulator valved stove could operate on a canister that, to a needle valved stove, was exhausted.


ENVIRONMENT
Location:  Stove Test Area 1 (UTM: 11S 383294 3792457), Haines Canyon, City of Los Angeles, California, USA
Date/Time:  thirty JUL 2011, 1830 hours
Elevation:  2600'/792m MSL

Conditions:
27.20 InHg/921 mBar
80F/27C
Little to no current of air (no audible susurrus, no visible leafage motion)


EQUIPMENT
Regulator Valved Test Stove:
-Soto OD-1R Micro Regulator



Conventional needle valved stoves for comparison:
-MSR Superfly


-Optimus Crux


-Snow Peak GST-100

All stoves together:



Fuel:
-Canister 1.  Snow Peak 110g, weighing 88g
-Canister 2.  Snow Peak 110g, weighing 93g
-Canister 3.  Snow Peak 110g, weighing 166g

Ignition source:  Soto Pocket Torch. 



TEST RESULTS
Test 1, canister 1 (88g)
A.  Superfly, valve fully open, flaming on, run to exhaustion.  Flame out.  Cannot restart.  No audio of gas escaping.
B.  OD-1R, valve fully open, cannot showtime stove.  No audio of gas escaping.
C.  GST-100, valve fully open, cannot showtime stove.  No audio of gas escaping.
D.  Crux, valve fully open, cannot showtime stove.  No audio of gas escaping.

Test 2, canister 2 (93g)
A.  Crux, valve fully open, flaming on, run to exhaustion.  Flame out.  Cannot restart.  No audio of gas escaping.
B.  OD-1R, valve fully open, cannot showtime stove.  No audio of gas escaping.
C.  GST-100, valve fully open, cannot showtime stove.  No audio of gas escaping.
D.  Superfly, valve fully open, cannot showtime stove.  No audio of gas escaping.

Equipment Checking, canister iii (166g).  Each stove tested for normal operation.
A.  Superfly.  NORMAL


B.  Crux.  NORMAL


C.  GST-100.  NORMAL


D.  OD-1R.  NORMAL.




DISCUSSION
Two rattling nigh empty canisters of gas were used to acquit the experiment.  Influenza A virus subtype H5N1 3rd canister containing far to a greater extent than gas was used to verify that each stove used inwards the experiment was working properly.  All stoves were inwards fact working normally.  To avoid the peril that the results mightiness live skewed past times about unknown, odd characteristic inwards 1 of the needle valved comparing stoves, multiple comparing stoves were used.  Influenza A virus subtype H5N1 butane torch was used every bit the ignition beginning for all stoves whether or non a given stove had a piezoelectric ignition thence that ignition failures could non skew the results.  At random, a needle valve stove was chosen together with used to exhaust the canister.  When flaming out occured, a brief re-ignition was apace attempted inwards lodge to confirm exhaustion of the canister.  If the re-ignition failed, the needle valve stove was swapped out for the regulator valved stove, together with an endeavour to run the regulator valved stove was made.
I ran ii tests.  See TEST RESULTS department higher upwardly for details.  In both cases, the Soto OD-1R could exercise no to a greater extent than than a conventional needle valved stove.  An exhausted canister to a needle valved stove was an exhausted canister to a regulator valved stove.  For additional confirmation, subsequently the exam amongst the Soto OD-1R, the remaining needle valve stoves were tried.  No stove was able to operate subsequently intitial exhaustion.  Influenza A virus subtype H5N1 exhausted canister was an exhausted canister, irrespective of the stove used.  After the test, canister 1 weighed 86g, together with canister 2 weighed 86g.

CONCLUSION
Influenza A virus subtype H5N1 Soto OD-1R regulator valved stove is non able to toilet off to a greater extent than gas from a canister than a conventional needle valved stove.  This is non to enjoin that a regulator valve mightiness non convey about value inwards keeping a flaming constant every bit canister pressure level drops, simply when the canister is lastly exhausted, a Soto OD-1R regulator valved stove offers no wages over a conventional needle valved stove.
