[Stoves] Fwd: the new 500 gasifier burner

[Ronal W. Larson]

Lists:

	This should be of interest to many on both the stoves and biochar lists - the cost numbers below are very impressive.  I am uncertain that it is OK for me to forward, but I will accept the blame as I find Paul’s numbers are so exceptional.  Does anyone know of a unit that is larger and/or lower cost?

	We usually see $/kW for electricity on the order of $1/W = $1000/kW, but here we have a thermal number that is (conservatively)  $150/50 kW = $3/kW - about 2.5 orders of magnitude lower.   Plenty of chance to couple this with an electrical generator to give low cost electricity AND char.

	Paul -  nice work.

> I redesigned the burner for the 500 gasifier.
> This is what it looks like:
> https://dl.dropboxusercontent.com/u/22013094/500%20Gasifier/Drawings/013.pdf
> The reactor holds 55 kgs of pellets.
> The pellets consist of 50%/50% rice hulls and coffee husks by volume.
> The burn time on pellets is over 2.5 hours.
> It is ideal for drying coffee parchment beans or paddy rice.
> 
> This 500 gasifier can be sold for as little as $150 US.
> It should put out about 55 kW of heat.
> 
> There are two advantages here:
> heat is more evenly distributed
> 150 gasifier parts are used (no new punch-cutting molds required)
> 
> Thanks.
