Beehive coal in daily life, mostly used for heating home fires and so on. Honeycomb coal is a honeycomb-shaped cylindrical briquette made from anthracite. By carbonized sawdust, raw coal, yellow mud, lime, red mud, charcoal powder and so on mixture of base material and by nitrate, potassium permanganate and other flammable accelerant composed of round honeycomb hole. It's his construction process is very complex.

Preliminary preparation of the necessary powder, there are three methods of the first method for the preparation of ultra-fine powder technology, refers to the particle size of about 20 ~ 110 nm micro-fine powder into a powder. The second method is the fast solidification atomization powder preparation technology. Through a variety of atomization means, such as two-flow atomization, gas atomization, high-pressure water atomization, centrifugal atomization, vacuum atomization, etc. will be tiny particles so that the coagulation into powder. The third method is mechanical alloying powder making technology. This technology is a kind of technology to make unbalanced alloy powder or composite powder from elemental powder. Later we prepare raw materials straw powder and poor quality coal phase, through their combination and then added the desulfurizer slaked lime, to paraffin and heavy oil formulated.

We pile the powder into a heap to go to an open place to the poor quality of the crushed coal ash piled into a small pile, like a heap into the shape of a mountain package will be mixed and then dug holes in the center. So that we can pour water in it to mix it. We pour enough water into the center of the pile, not so much that it runs out. Then we mix the coal ash with the water by means of a tool, such as a trowel, so that the ash is well moistened. After about twenty minutes, the water will have fully saturated the coal ash. At this point we stir the new pile of coal ash once again. We keep in mind that the coal ash should not be too wet. At this time, we take out the molds, press the honeycomb molds into the mixing pile of coal ash, compaction and flattening and then remove. Take the mold to an open area and press out the honeycomb coal. Through the above steps a piece of honeycomb coal has been completed, we just need to wait for it to fully dry.

I think the construction process of honeycomb coal is complicated.
