[Stoves] Patong Patong The Brick Stove Carbonizer Jan to June 2015.pdf

[Joshua Guinto]

Dear Crispin

Thanks for the compliments.

About the pot rest, its still early to tell as the stove is just a few
weeks old. But that will be a good point of observation, that is if it gets
coated with sooth or the sooth gets burned all the way.

I would like to promote the char making mechanism of this stove for several
reasons.

First is the charcoal here at my locality is more expensive than raw fuel.
Canarium yields a premium kind of charcoal. The following is my quick
computation of the local market prices of fuel and charcoal:

*One set of meal for a person of six require about 2 kg.  of  canarium
shells at a cost of Php 8 per meal or Php 24 daily. After each day, about
1.5 kg of char may be harvested and this has a market value of Php
37.50 !!* Thus
a net of Php 13.50 daily.

Retail stores sell charcoal at Php 10 per 400 gram packets. A family
consumes at least 3 packets daily or at least Php 30 daily for wood
charcoal for their meals.


Another reason is because the char from gasification is of higher quality
(porosity) than charcoal produced from conventional earth kilns. As an
independent consultant, I am actively involved in waste management and
urban gardening campaigns at disaster prone communities here in the
Philippines. Stoves, bio char, waste management, sanitation and gardening
comes  tightly altogether.


Regards

> I hereby share with you the second stage of my work on the brick stove
> gasifier/carbonizer. It began from the lessons i learned during the 2014
> Stove Camp at Aprovecho. where i learned how to overcome the limitations of
> the holey roket i built. It was then when i realized the low firepower of
> the stove, the difficulty of feeding the fuel and the fragility during
> transport.

> Please see https://drive.google.com/drive/my-drive

> From November 2014 until now, i tinkered with so many fronts:preparing the
> best clay recipe, pulling in secondary air, making the shape and size of
> each bricks, creating the moulds, designing the fuel ports, the air
> controls, the metal shell, the pot rest, harvesting the char etc.
>
> I hereby share with you all my work in the attached photo narrative. At
> the same time i would like to solicit more comments on how to improve
> further, Also i would like to find support to have this stove model tested

> A smaller model for the kitchen in now underway on a test manufacturing

> Kind regards to everyone.
