Camping firewood stove can burn for hours

It depends on what wood you use. Generally, the burning time of fruit trees is longer, among which the old jujube wood has the longest time, and the peak fire for ten hours is about 100 kg; The second is hard miscellaneous wood, such as elm, locust and so on, followed by pine, which has a relatively short combustion time; Finally, there are walnuts, tung trees and toon trees, which have the shortest burning time. In short, the faster the tree grows, the shorter the burning time is.
