Abstract
A grid for distributing and mixing fluids in a duct includes a plurality of lances arranged in a first plane and configured to be positioned transverse to a direction of a first fluid flowing outside of the lances and within a predetermined flow area. Each of the plurality of lances has at least one first inlet and a plurality of outlet nozzles. One or more of the outlet nozzles is directed generally in the flow direction of the first fluid outside of the lances, and is configured to discharge a second fluid therefrom.

A distribution and mixing grid for mixing fluids in a duct comprising:
- a plurality of lances arranged in a first plane and configured to be positioned transverse to a direction of a first fluid flowing outside of the lances and within a predetermined flow area;
- each of the plurality of lances having at least one first inlet and a plurality of outlet nozzles;
- and
- at least one of the outlet nozzles being directed generally in the flow direction of the first fluid flowing outside of the lances, and configured to discharge a second fluid therefrom.
The distribution and mixing grid of claim 13, further comprising a sleeve, the first closed end and the second closed end being moveably positioned in opposing ends of the sleeve.
An oxy-combustion system comprising:
- a furnace defining an interior combustion area;
- an oxygen supply system;
- a fuel supply system defining a primary flue gas inlet and a fuel outlet;
- at least one flue gas processing system positioned downstream of and in communication with the furnace;
- a primary gas system defining a primary flue gas outlet, the primary gas system being in communication with the at least one flue gas processing system and the primary flue gas outlet being in fluid communication with the fuel inlet;
- a secondary gas system defining a secondary flue gas outlet, the secondary gas system being in communication with the at least one flue gas processing system and the secondary flue gas outlet being in communication with the furnace;
- the at least one oxygen discharge line being in communication with at least one of the primary gas system and the secondary gas system;
- and
- a grid positioned in a duct of at least one of the primary gas system and the secondary gas system, the grid comprising:
- a plurality of lances arranged in a first plane and positioned transverse to a flow direction of a flue gas outside of the lances and within a predetermined flow area;
- each of the plurality of lances having at least one oxygen inlet and a plurality of outlet nozzles, the oxygen inlet being in communication with the oxygen supply system;
- and
- at least one of the outlet nozzles being directed generally in the flow direction of the of flue gas outside of the lances, and configured to discharge oxygen therefrom.
