[Stoves] Boiled 520 grams of 14C water in 3:20 minutes

Sun May 5 16:17:17 CDT 2013

Paul,

In the past I did not use fans. There is, currently, too large a fan at the base of the Rim Fire iCan. Without a fan, or a draft inducing "stack", I do not think there is any way that a Belinio, Olivier, or Rim Fire iCan would work.

One if the advantages of a fan is eliminating the need for a stack and thus being able to place pots and pans as close to the flames as possible.

Hugh has been trying to get me to play with fan powered stoves for a long time.

I will see about shipping you a unit for testing. But first I have some more work to do on the design MRI improve it a bit.

Thanks for your interest.

Cheers,

Jock

The air is coming from the outer side of the annulus.   Difficult for secondary air to be on the inside of the annulus except what can come in from over the top of the flames.

The unit needs to be sent to Aprovecho by July or to me in Illinois by mid July so that I can take it with me in my car.

>> The design I am working on was informed by the work of Prof. Bolinio and Paul Oliver.  They place a cap, a burner plate with two rings of holes for blue flamelets,  over the reactor and only introduce secondary air above the cap.  The cap effectively seals the reactor chamber, preventing any secondary air from entering.  This creates something of a hybrid between a TLUD and a Retort: a TLUD with a a bit of Retort flavor.

My solid burner plate is sized to allow for a gap between the wall of the reactor chamber and the edge of the plate.  Thus the gases emerge from the reactor via this gap at the edge.  They can thus only meet secondary air above the gap.  Secondary air is thus prevented from entering the pyrolysis chamber - as per Bolinio and Olivier.
