Definitions

  • the present disclosure relates to the continuous production of charcoal from chipped hard wood and soft wood, forest and orchard thinning, residues from sawmills and similar wood working industries, and in particular to a non pressurized reactor for carbonizing wood to charcoal in an energy efficient manner while recovering valuable wood vinegar from the wooden biomass fed into the reactor.
  • FR 2.416.931 discloses retorting reactors for charcoal production based on the use of an up-right retorting vessel or tower.
  • a less energy wasteful carbonization process has been sought by collecting the hot pyrolysis gases released by the biomass undergoing carbonization and using them for pre-drying (hot purging) the fresh feed wood, or by burning them in a burner eventually admixed to another fuel for generating hot flue gas to be injected in the pyrolysis zone.
  • a twin-retort carbonization unit is described in the article "Charcoal production with reduced emissions” by P. J. (Patrick) Reumerman and D. (Burt) Fredericks presented at the 12 th European Conference on biomass for energy industry and climate protection, Amsterdam, 2002.
  • the document CN 101693842 discloses a biomass high pressure retort for producing charcoal employing a high-pressure retort disposed horizontally at a certain height and employing motor driven mixing means for maintaining the retorting biomass under constant intermixing, a horizontally disposed, charcoal transfer unit, placed below the high pressure retorting vessel, adapted to receive through a vertical pipe the fully carbonized mass of charcoal expelled out the high pressure retort and having a variable pitch screw conveyor adapted to disintegrate the larger pieces of charcoal to reduce the particle size and pack them more and more densely together while advancing the material such to practically form a gas locking diaphragm in the discharge path of the produced charcoal.
  • a third screw conveyor receives the compacted mass of particles of charcoal expelled at the end of the crush and pack variable pitch screw conveyor, through a vertical pipe, advancing it while being cooled by water flowing in a gap space around the screw conveyor wall. Also in this retorting apparatus hot purging gases are circulated inside the pressurized horizontal retort.
  • Orchard and forest thinning, chipped wood from fallen trees and similar wooden wastes, sawdust and discards from wood milling plants before the carbonization process may begin undergo a practically complete drying phase.
  • the fresh wood is exposed to streaming hot purge gases that gradually strip the moisture and other vaporized substances contained in the wood. This drying process normally occurs at about 140-280°C.
  • the hot purge gases are then ducted to a burner whereat by injection of air, combustible gases are burned for generating new hot purging flue gas to be reinjected inside the retorting vessel.
  • Freshly cut wood will contain more vinegar that long stocked wood.
  • Freshly cut wood may contain up to 7% by weight wood vinegar; bamboo just about 1.5%.
  • Extraction of wood vinegar is economically important. For example 1 ton of wood will produce approximately 500 kg of charcoal that can be sold at 10 Baht/kg, generating a revenue of 5,000 Baht. From the same one ton of wood, from 15 liters (1.5%) to 50 liters (5%) of wood vinegar may be recovered that can be sold at 300 Baht/kg generating a revenue of 4,500 - 15,000 Baht, that is generally much higher than that of the corresponding charcoal.
