RE-ENGINEERING EXAMPLE

500 MW B&W Opposed-Wall Fired Boiler Pulverized coal -24 Coal Burners

Remove PC Burners and Wind-Box (in green)
Brick over the Burner Ports

Re-Engineered Power Plant with CCS Technology:

• Reroute Flue Gas to Pulverizers, Add Pulverized Coal/Sweep Gas Bag house, Duct sweep gas around boiler to flue gas exit
• Replace PC Burners & wind-box with 24 new CCS Burners & 6 new Gasification Chambers with bottom ash disposal system
• Add new ducting and OFA ports to boiler furnace- Convey me-

CCS-Stoker^® Re-Engineering
(30 MW_M 5 T/h Coal)
Remove:

• Stoker Feeders
• Ash Hopper
• Control Panel

New Equipment:

• CCS Burner
• Gasification Chamber
• Combustion Air Heater
• Boiler Instruments
• Coal Mill, Bag house, FD fan, BM & Combustion System
• HMI & PLC Controls
• New/Update MCC Panel

Installation & Construction:

• Replace stoker feeders with new CCS Burner and gasification chamber
• Add over-fire air ports and ducting and combustion air pre-heater
• Add coal pulverizer and coal-air separation bag house, Provide powdered limestone metered with the coal
• Brick over furnace bottom, provide bottom ash removal system
• Update instrumentation, add HMI and CCS Burner management, & Safety Control System

Operation (one operator/shift):

• Was manually operated
• Now from HMI panel - from cold start to automatic full load operation in 5 hrs.
