Develop an advanced dry CODevelop an advanced dry CO22 capture system applicable for both PF and CFB boiler.capture system applicable for both PF and CFB boiler.

Two options for COTwo options for CO22 capture from boiler systems are investigated: an integrated capture from boiler systems are investigated: an integrated atmospheric fluidised bed system for postatmospheric fluidised bed system for post--combustion capture from PF or CFB boilers, combustion capture from PF or CFB boilers, and an inand an in--situ capture system for PFBC boilers. situ capture system for PFBC boilers.
