Rocket stoves aren’t anything new, but there are still plenty of people who haven’t heard of them. Most preppers have either heard about rocket stoves or even built one of their own. In case you fall into one of the groups of individuals who haven’t had the luxury of learning about these amazing little stoves, then read on to find out more! I bet you’ll find them to be super cool and quite useful as well.
What is a Rocket Stove?
A rocket stove consists of four components: a fuel magazine, a combustion chamber, a chimney, and a heat exchanger. The fuel magazine is the area where unburned fuel is placed to slowly feed into the fire. The combustion chamber is where the fire burns the fuel. In order to provide updraft necessary to burn the fuel, a chimney is needed. As for the heat exchanger, this is where heat is transferred to where it is needed most, such as to a cooking pot.
These efficient stoves can be used for cooking or heating an entire home, depending on their size. The one in the pictures was a small model used solely for cooking. Read What is a Rocket Stove and Why Do I Need One for even more information!
How does it Work?
Small bits of fuel, such as newspaper or sawdust, must be added to the combustion chamber and lit. This will heat up the chimney to create an updraft. Fire in the combustion chamber and an active updraft are needed before fuel in the fuel magazine will burn efficiently.
As the combustion chamber becomes hot enough to require more fuel, pieces of wood setting in the fuel magazine are slowly slid into the fire to keep it burning steadily. Once the desired temperature is reached, a constant supply of fuel is necessary for keeping a room warm or for cooking food.
Why would you Need one?
If you have a small building or a room you want to heat for very little money, then a rocket stove might be something to look into. As for a personal cooking stove, you simply cannot beat a small rocket stove. They are easy to transport, use very little fuel (if it burns, you can use it!), and they are also simple to operate.
Try Building one on your own!
I’ve made my own rocket stove for heating food or boiling water and it was amazingly easy. I had a blast building it and if this is something you might also be interested in, then take a look at these simple instructions: Building a Rocket Stove: Step By Step Tutorial. Supposedly, the argand lamp was a precursor to the rocket stove.
The chimney on these lamps increased airflow and enabled people to use them for not only lighting, but also for heating water and cooking. People in third-world countries have used rocket stoves for decades, due to their lack of access to large amounts of fuel for cooking. Even try weeds can be used to fuel a rocket stove!
