This invention discloses an energy-saving biomass honeycomb coal. The honeycomb coal is prepared from: coal 10-30 wt.%, clay 20-40 wt.%, charcoal 45-60 wt.%, potassium nitrate 0.05-0.2 wt.% and paraffin 0.05-0.2 wt.%. More specifically, the honeycomb coal is prepared from: coal 18.2 wt.%, clay 27.3 wt.%, charcoal 54.3 wt.%, potassium nitrate 0.1 wt.% and paraffin 0.1 wt.%. The honeycomb coal has such advantages as strong combustion, long combustion time, and easy ignition, little smoke during combustion, simple production process and convenient usage. |
