Technical Field

The utility model relates to a stove technical field especially relates to a firewood stove with novel supporting network.

Background

At present, outdoor camping is increasingly popular with the public. Many people can carry a camping firewood stove when going out for camping.

Because of the size relationship of the burning materials, the firewood stove is generally used for burning either wood or particles. But when burning the granule, because the supporting network of current firewood stove is comparatively level and smooth, the granule enters into the furnace chamber and piles up the ventilation effect that makes the supporting network on the supporting network and can't ventilate even, and then makes the interior combustion effect of firewood stove poor, influences the performance of firewood stove, causes a great deal of inconvenience.
