Abstract
A combustion device includes a stove body and a flow guiding device. The stove body has first and second sides disposed oppositely and includes a wick disposed between the first and second sides. The wick is spaced from the first and second sides at first and second distances respectively. A flow guiding device includes first and second shielding members respectively connected to the first and second sides of the stove body. The wick is spaced from the first and second shielding members at third and fourth distances respectively. The third distance is greater than the first distance and the first shielding member is spaced from the first side. The fourth distance is greater than the second distance and the second shielding member is spaced from the second outer side.
