Foster Wheeler Does not Require Additional Bench Scale or Pilot Scale
 
and Operational Feedback from the Replicated Existing Boilers
The Proposed Boiler is Designed to Ensure that the Boiler is Protected
Against Damage Due to Transient/Upset Conditions
All Auxiliary Systems (Fuel Feed, Air Feed, etc) are Adequately Sized to
