Description

What is a rocket stove?

To understand better, here is a little detailed illustration of the Rocket Stove composition (clic to enlarge) :

Schéma Rocket Stove

To sum up, it is a mass stove with a semi open firebox composed of :

  • Fuel magazine allowing air to get in and the introduction of fuel (wood) ;
  • an insulated combustion chamber  ;
  • an outflow chimney.

It is the insulation that is responsible of the excellent wood conbustion. This combustion being complete, there is very few smokes.

On a side note : the Rocket Stove takes its name after the sound it makes during combustion, which sounds like a rocket.

Why consider the rocket stove as a serious option?

In 5 shock-arguments:

  • Costs are light (about $600).
  • Poor wood consumption for a great energy efficiency.
  • Reduction of the emissions of carbon monoxyd (very few smoke).
  • Attractive and adaptable to (almost) everyone tastes.
  • 3-in-1 : heating, hot water, cooking.

Out of salvage?

The Rocket Stove can be entirely auto-build out of salvage, or inexpensive :

  • The admission barrel : a barrel or a gaz bottle.
  • The combustion tunnel : built with refractory brick.
  • The heating column : a stove-pipe.
  • The insulation container : a drum or a slab of steel.
  • The exposed barrel : a drum, bigger than the first one.
  • The insulation : vermiculite.
  • The draught key : pretty cheap at the hardware store.
  • The outflow pipe : at the scrap metal merchant.
  • The “banc de chaleur” (the heating bench): “bauge” (clay + straw + stones)

How to make it?

Well, look at the illustration above :) !

There are still few things to know :

  • The heating column has to be between 2 and 4 ft.
  • The outoflow pipe has to present a light slop.
  • Use clay to stick bricks among themselves and insure the seals between pipings.
  • The whole of the installation must be installed on a refractory bricks bed.
  • Warning : don’t use galvanized iron (produce toxic vapors!).
  • Build a test outside to check the combustion, the supplying, the ventilation and the shape.
  • Do not forget, if necessary, to sand the barrel.

And for hot water?

Roll a copper wire up around the heating column and connect it to the water tank.

Conviced?

The realization of a Rocket Stove is quite easy but we advice you to check few examples first.

The Rocket Stove is traditionnaly used as a heating system but it can also :

  • Heat a water tank,
  • Be used as a baking tray.

Furthermore, it is auto-build, that means (almost) everything is possible in terms of shape so it fits better in its environment.
