Title:
PROCESS TEMPERATURE CONTROL IN OXY/FUEL COMBUSTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/036852
Kind Code:
A3
Abstract:
An oxy/fuel combustion system having a furnace arranged and disposed to combust a fuel to form a combustion fluid. The system further includes a convective section having at least one heat exchanger arranged and disposed to exchange heat between the combustion fluid and steam for use in a steam turbine. A flue gas recycle is arranged and disposed to recycle at least a portion of the combustion fluid as a recycled flue gas, the flue gas recycle having at least two expellant locations downstream of a primary combustion zone. The system includes a flow control mechanism that provides controlled amounts of the recycled flue gas to the at least two expellant locations to control temperature of the steam.
