Gasification furnaces include fixed-bed, fluidized-bed, and pneumatic-bed types. What are the respective processes represented by each of them, as well as their simplified operation procedures?

Project: Moving-bed gasification, Fluidized-bed gasification, Gas-flow bed gasification
Coal particle size/mm: 3–30, 1–5, <0.1
Suitable coal types: Non-caking coal, Coals with low caking tendency; basically no restrictions
Feed method: Lump coal (dry), Coal powder (dry), Coal powder (dry) or coal slurry (wet)
Slag/ash discharge method: Dry ash discharge or liquid slag discharge, Dry ash discharge or agglomerated ash discharge, Liquid slag discharge
Gasification temperature/°C: 450–1000 (dry ash discharge), 600–1600 (liquid slag discharge), 850–1100, 1500–1800
Carbon conversion rate/%: High (>99.7), Low (>95), High (>99)
Cold gas efficiency/%: High (about 89), Medium (80–85), Low (76–80)
Production capacity: Low, Medium, High
Representative technologies: W-G furnace (at atmospheric pressure), Lurgi furnace, BGC/Lurgi (BGL) furnace, Winkler furnace, HTW furnace, U-Gas/KRW furnace, Texaco/E-Gas (coal slurry feed), Shell/Prenflo/GSP (dry powder feed)

It’s better to copy it down and organize it in a table by yourself~~~~~~~

Not all; there are also the space furnace, Tsinghua furnace, and Five-Ring furnace
