Definitions

  • the cyclone 220 is provided above the gasifier 240.
  • the cyclone 220 solid-gas separates the solid-air mixture of the flow medium F and the combustion exhaust gas EX introduced from the combustion furnace 210 through the second duct 214.
  • the third duct 222 connects the bottom of the cyclone 220 to the gasifier 240.
  • the third duct 222 is provided with a loop seal (not shown).
  • the high temperature flow medium F separated by the cyclone 220 is introduced into the gasification furnace 240 through the third duct 222.
  • the refining device 250 purifies the gasified gas GG produced by the gasification furnace 240.
  • the purification device 250 includes, for example, a heat exchanger, a direct cooler, a mist remover, a booster, and a wastewater treatment device.

Abstract

La présente invention concerne un système de fabrication (100) de gaz gazéifié qui comprend : un réservoir de réception (130) qui reçoit une matière première solide M et de l'eau W ; une unité d'alimentation (140) en gaz d'échappement de combustion qui fournit un gaz d'échappement (EX) de combustion à l'eau W contenue dans le réservoir de réception (130) et/ou l'eau W avant qu'elle W ne soit fournie au réservoir de réception (130) ; un four de gazéification (dispositif de fabrication (170) de gaz de gazéification) qui gazéifie la matière première solide M, après retrait du réservoir de réception (130), avec de la chaleur provenant d'un milieu de fluidisation ; un four de combustion (dispositif de fabrication (170) de gaz de gazéification) qui chauffe le milieu de fluidisation par combustion d'un combustible ; et un séparateur à cyclone (dispositif de fabrication (170) de gaz de gazéification) qui sépare un mélange solide-gaz produit par le four de combustion et comprend le milieu de fluidisation et le gaz d'échappement EX de combustion en solide et en gaz. L'unité d'alimentation (140) en gaz de combustion fournit le gaz d'échappement EX de combustion séparé par le cyclone.
