Forced Convection Stove
Hello dear hobbyists and viewers! Once again I am adding another page of a hobby project in this website. This time it is about a forced convection type stove. Strictly speaking I did not make this hobby project. A family friend made this project from a school project of one of his schoolkid-age relatives. He has actually began selling units of this in his area in the province. He just asked me to include his project in my website so it could generate viewership and also if possible be able to also generate revenues from those who would patronize such product.
Because I believe in utilizing our resources efficiently I agreed to assist him. This is also somewhat in harmony with my interest in renewable energy as the stove uses a renewable fuel: CHARCOAL.
In the Philippines where a lot of households, even in the cities, still use charcoal stoves to cook their food, primarily because of the affordability of the fuel, this is a novel approach. Ordinary charcoal stoves use the principle of natural convection to continuously push air to burn the charcoal. However this is not a very efficient way to do it as sometimes the air is not enough, hence you see much smoke or the charcoal is not burning properly. Thus the fuel is not utilized properly also.
With the use of a detachable centrifugal-type blower(see picture below), air is forced upward inside the stove chamber, passing through the charcoal pieces, thus ensuring proper combustion of the fuel.

The blower itself is powered by a cellphone charger which consumes a very small power. Thus there is no need to fan the charcoal flames manually and ensures high heat delivered to the pot placed on top of the stove.
I have seen one of the units in action. There is minimal smoke generated and the heat is more intense with fewer charcoal pieces needed to cook food. It might even be used indoors as not much smoke is generated. After using, one can remove the blower and easily remove the collected ash.
For those who would be interested to purchase a unit, I placed an advertisement at sulit.com.ph for this product. Just type in the search box "Charcoal stove - forced convection type". Remember this is just an outgrowth of a school project that was turned into a small business. Sort of like a hobby also that became a basis for a very small enterprise. That is why I would like to support also in the promotion of it. Not to mention that it also helps our environment if we use truly renewable fuels in a more efficient manner. :)
