The aforementioned charcoal fuels are chunks of charcoal, and most of them are stacked in the holding part 10A. The charcoals are irregular chunks and are formed with the stack such that they can be aligned in the holding part 10A sufficiently. In order to standardize all the elements, the charcoal fuels can be formed by dense charcoals that are finished with wood fibers and are provided with a same shape. By having the same shape, the charcoal fuels can be orderly aligned in an emplacement space of the holding part 10A, which can sufficiently use the internal space of holding part 10A, and can form an explicit alignment as matrixes or layers to the standardized dense charcoals for making an angular orientation for receiving fire attack, particularly.

Upon igniting the fire precursor 3, air A which is needed is fed in from the drain-in hole 12 that is disposed as at least one hole. Other three sides of the box are used to fix and maintain the fire precursor 3, so as to prevent combustion of the fire precursor 3 from being directly affected by exterior air-flow.
Hot air which results in burning will flow upward t and be guided by the leading hole 11 of the upper lid 13; it will be accumulated at a center to float upward. The upper charcoal fuels 2A or the central parts will receive the heat of the hot air to form a pre-heating operation; therefore, they are easier to be ignited than other peripheral charcoal fuels. Accordingly, the entire heat energy will be concentrated at the center of the holding part 10A, and by three-dimensional transmission of thermal radiation waves, heat waves will be transmitted out from the center of stacked charcoal fuels 2, thereby approximately achieving the total ignition.

The assembly of present invention uses a box to enclose the internal charcoal fuels and to divide into the firing space for emplacing the fire precursor. Moreover, the oxygen drain-in hole and hot air leading hole which are connected to the exterior of the box are used to facilitate an operation of camp fire, such that as long as the fire precursor is ignited, the box can be left alone without caring to combust by itself. In the aforementioned procedure, after the hot air has first attacked to the pallet and the lower charcoal fuels, the central parts of the fuels are ignited in advance through the guiding of the leading hole, and then the thermal radiation waves which result from the ignition of the central parts are emitted to the peripheral charcoal fuel stacks, such that the charcoal fuels can approach to the total self-combustion. On the other hand, as the box is in a vertical shape, and its upper part is loaded with the charcoal fuels, the box will be crashed down by losing its structural intensity after burning out the pallet and the box. During the crashing process, the single charcoal fuel can be rotated by an angle and paved flat, such that the charcoal fuels can be effectively distributed on the upper end of the stove plate of the stove, thereby facilitating a user to ignite the raw and cold charcoal fuels.
The present invention is so convenient that even a kid who knows about fire safety can use it to easily ignite the raw and cold charcoal fuels, and the fuels will be turned into ashes and be mixed in earth after burning, which will be transformed into an organic fertilizer and be completely contained, thereby facilitating carrying cleanly, transporting, displaying, and exhibiting, which is a rather convenient innovated invention.
