Multi-Fuel Stove
The stove shown here can use multiple fuel types. Most commonly, kerosene or butane is used. Kerosene is safe to handle and hard to light. If a lit match is dropped into a cup of kerosene, the match will be extinguished. Kerosene is preferred for safety. Butane is relatively safe. The vapour pressure in canisters is low. Leaks and bursting containers are rare. Butane liquifies at 0° Celsius, so use in low temperatures may be degraded. With this stove, the option of kerosene provides a low-temperature option. Butane offers convenience. Connect it and start cooking. Kerosene needs time to heat up the stove before it the heat level can be raised.
Kerosene Stove
The pressure stove shown here runs on kerosene. This stove provides enormous heating potential using liquid kerosene fuel. Lighting this stove is challenging. Kerosene requires high temperatures to burn. This stove has a small preheating cup that is filled with a small amount of alcohol before lighting. The burning alcohol preheats the areas where the kerosene travels. Once the burner is hot enough, the tank may be pressurized so that kerosene flows into the burner. The tubing that carries the fuel to the burner passes through the flame. The flame hears the tubing to a temperature where the kerosene is vapourized. Vapourized kerosene fuel is delivered to the burner area, where it burns with great efficiency.
Butane Fuel Canister
New butane cans should be weighed and tracked as fuel is used. This gives you a great way of knowing how much fuel is left in them. In the example below, the new can weighs 351.53 grams. The tare weight (no fuel) is calculated to be 101.53 grams (based on 250 grams). The fuel in the can may vary by ±five grams.
Cooking
Cook as you usually do, but be aware this stove can put out a lot of heat. Less is more! Simmer your food for less burning and less fuel use.
Empty Butane Canister
After a week of cooking with this stove, my butane canister is out of fuel. Using 250 grams of fuel for a week is pretty good. Running this stove on propane lowers the cost of use significantly. In the photo below, this butane canister had a variance of five fewer grams. For breakfast, I typically use eight grams of fuel. If I ran out after three grams of fuel, I would use the residual heat in the iron skillet to finish cooking an omelette.
Recycling Used Butane Canisters
The butane canisters shown here are not refillable. Recycle them safely. Ensure they are completely empty, puncture the tank (outdoors), and flatten the canister. I used a can opener to safely puncture the empty can.
Propane Usage
Propane and butane have similar costs. Butane costs more due to its exclusive availability in non-refillable containers. Propane has a similar high cost when using non-refillable containers. With a refillable container (depicted below), propane costs are quite low.
My tank is 624 grams when empty and 1072 grams when full. The calculated fuel weight is 448 grams.
You can further protect the propane hose by adding a 30 mm rubber grommet to the stove. Watch it here on Youtube: A Simple Modification to a Portable Stove Protects a Propane Hose. The exact grommet needed to add extra protection is available on Amazon (affiliate link): Flyshop 4-Pack Round Double-Sided Black 30 mm Rubber Grommet.
The much smaller propane tank in the above photo holds 50 g of fuel. The tank is primarily intended for use with a culinary torch. This tank is available here: Amazon Link (affiliate link).
