How does a rocket stove heater work?

A rocket stove is an efficient and hot burning stove using small-diameter wood fuel. Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames reaching the cooking surface.

How hot do rocket stoves get?

As a result, the exhaust temperature of a functioning rocket mass heater can average around 60–90 °C (140–194 °F), which is lower compared to that of a conventional wood stove, which averages around 400–600 °C (752–1112 °F).

How many Btus does a rocket stove produce?

“SR100” is a rocket stove engineering specification: “The SR100 Rocket Stove shall be capable of producing 100,000 btu of heat per hour 24 hours a day, seven days a week, continuously for six months without failure, and cost less than $300”.

Where does the heat go in a rocket stove?

The current of heat will spiral upwards until it comes into contact with the heat riser inside of the drum. The role of the drum is for it to heat up and warm the room. Once the drum is hot enough, the heat will then fall down the sides of the riser into the horizontal chimney which will then provide heat to the bench.

What do you need to build a rocket stove?

Most people build these stoves with bricks, cement, rocks or even clay. First, a fire needs to get started inside the combustion chamber as illustrated in the image above. Once the fire is ready, you can then fill it by adding sticks to the fire pit or combustion chamber.

How to make your own rocket mass heater?

You can either use a large drum or build your own metal plated box with a grid inside. Use the same principle as that of the geyser and place the drum or box on a stand. Connect the rocket oven from below and you now have an oven. You can place a grid and a thermometer inside complete your creation.

What kind of wood is used in a rocket stove?

These stoves mainly consist out of two parts which include the horizontal feeding tube and the vertical insulated chimney. The fuel used for rocket stoves comprises of small diameter wood such as dried branches and sticks which can also be called kindling. First, you need to get a fire going inside the stove before you can fuel it with kindling.
