Definitions

  • the invention relates to the field of thermal processing of solid fuels with a low organic content, for example, oil shale, and can be used in the fuel processing industry in the production of liquid or gaseous fuels or oil substitutes.
  • the method includes drying the crushed fuel with a gaseous drying agent, pyrolyzing the dried fuel with a solid heat carrier to form vapor-gas products and a coke-ash residue, burning the latter in a stream of heated air to form a gas suspension, stage-by-stage separation of the gas suspension into an ash coolant that is returned to the pyrolysis stage, and sent to cooling from the process, and flue gases sent for afterburning and then used as a gaseous drying agent.
  • the disadvantage of this method is that the afterburning of flue gases in the waste heat boiler at a ⁇ 1 leads to incomplete oxidation of the combustible components contained in them and, as a consequence, to environmental pollution by products of incomplete combustion of organic fuels.
  • Environmental pollution is also caused by the fact that during drying in an airborne dryer, a certain fraction of the fuel particles overheats, as a result of which bertination products pass to the spent drying agent: carbon monoxide, hydrogen sulfide, carcinogens, etc. which pollute the environment.
  • the method includes drying the fuel with a gaseous drying agent, separating the fuel from the spent drying agent, pyrolyzing the dried fuel with a circulating solid heat carrier to form gas-vapor products and a coke oven residue, burning the latter and forming a gas suspension, stepwise separation of the latter into a circulating coolant returned to the pyrolysis stage, gaseous drying agent directed to the drying stage, the ash mixture, cooling this mixture and separating it into ash removed from the process and flue gases that are sent to the drying stage.

  • the disadvantage of this invention is that it is not provided for the afterburning of flue gases from the airborne firebox, which leads to environmental pollution by products of incomplete combustion.
  • the objective of the invention is the provision of temperature control in an airborne furnace and reducing the size and intensity of the equipment.
  • a method of processing oil shale or high-ash solid fuels includes drying the feed with flue gas, isolating the solid phase as a coolant, pyrolyzing the feed in the reactor, separating the gas-vapor mixture and the coke-ash residue in the precipitation chamber, removing ash, cooling the flue gases, burning the coke-ash residue.
  • inert material with an ambient temperature is supplied to the exit from the ignition chamber of the coke ash residue to control the temperature in the airborne furnace, and as an inert material use ash from an ash removal system with a temperature of 10 to 200 ° C.

  • the ash from cyclone 6 is cooled in an ash heat exchanger to a temperature of ⁇ 80 - 120 ° C, then it is fed to humidification and subsequently for disposal. Unlike the prototype.) Part of the ash before it is moistened at a temperature of 80 - 120 ° C with the help of a screw is sent to the airborne furnace to exit the accelerating section of the furnace. In this case, the coke ash residue from the dust chamber ignited and the ash supply allows you to adjust the temperature in the furnace.

Abstract

L'inventions concerne la transformation thermique de combustibles solides possédant une faible teneur en partie organique et peut être utilisée dans l'industrie de transformation de combustibles. La transformation du schiste bitumineux ou de combustibles solides à teneur élevée en cendres comprend le séchage de la matière de base par des gaz de fumée, l'extraction de la phase solide utilisée comme agent caloporteur, la pyrolyse de la matière de base dans le réacteur, la séparation du mélange vapeur-gaz et du résidu de cendres de coke dans une chambre de sédimentation, l'évacuation des cendres, le refroidissement des gaz de fumée et la combustion du résidu des cendres de coke. On alimente la sortie de la chambre d'allumage du résidu de cendres de coke avec un matériau inerte possédant une température ambiante. Le dispositif comprend, montés en séquence, un réacteur, une chambre de sédimentation, un four à fontaine d'air, un cyclone pour l'agent caloporteur, un cyclone pour les cendres, un système de récupération de chaleur, un système d'évacuation de cendres et une trémie pour matériau inerte raccordée à la sortie de la chambre d'allumage du résidu des cendres de coke. L'invention permet une utilisation plus complète du potentiel énergétique du schiste et l'obtention de cendres à faible impact sur l'environnement, ce qui permet d'utiliser les cendres pour réhabiliter les carrières abandonnées lors de l'extraction de schiste.
