Quick Answer
A Swedish torch, also known as a Swedish fire torch or candle lantern, produces a moderate amount of smoke. This is due to its unique design, which involves a candle-lit tin can over a hole in a log. The smoke output can be managed to some extent with proper technique.
Design and Functionality
The Swedish torch relies on a candle-lit tin can, typically a #10 can, suspended over a hole in a log. This allows for a controlled flow of oxygen, which in turn affects the amount of smoke produced. By adjusting the height of the can and the size of the hole, you can manage the airflow and reduce smoke.
Managing Smoke Output
To minimize smoke, keep the can at a moderate height of 1-2 inches above the log, and use a small hole (about 1/4 inch in diameter). A smaller hole restricts airflow, resulting in less smoke. Use short, controlled breaths to maintain the flame and reduce excess smoke.
Tips for Use in Various Environments
When using a Swedish torch in windy conditions, anchor the log to prevent it from shifting and compromising airflow. In dry environments, be cautious of excessive soot buildup on nearby surfaces. Regularly clean the can and log to maintain efficiency and minimize smoke.
