A steam generating boiler having a matrix means for reducing combustion volume. Matrix means is placed in the combustion furnace of a steam generating boiler, preferably downstream of fuel and oxidant stream. Matrix means produces a shorter combustion envelope than that of a conventional boiler, allowing for reduced volume steam generating boilers.

We claim: 1. A steam generating boiler, comprising: and a combustion furnace having an inlet end, an outlet end, and further defined by a baffle wall and a plurality of furnace walls, wherein each of the furnace walls comprises a plurality of steam tubes aligned with the vertical length of the furnace wall and in fluid connection with a steam drum located on the opposite side of the baffle wall and downstream of the outlet end of the combustion furnace, a oxidant inlet positioned near the inlet end of the combustion furnace for providing an oxidant, a fuel inlet positioned near the inlet end of the combustion furnace for providing a fuel, a matrix means consisting of metallic spheres for passively mixing the oxidant and the fuel located downstream of the oxidant and fuel inlets, wherein the outermost edges of the matrix means are free from contact with the furnace walls and the baffle plate. 2. The steam generating boiler of claim 1 further comprising a second oxidant inlet located downstream of the matrix means and a second matrix means consisting of metallic spheres located downstream of the second oxidant inlet. 3. The steam generating boiler of claim 2, wherein the second oxidant inlet comprises a plurality of tubes extends horizontally along the width of the second matrix means and each of the plurality of tubes comprises multiple openings for dispersing oxidant. 4. The steam generating boiler of claim 3 further comprising a perforated plate consisting of a plurality of circular holes located upstream of the fuel inlet. 5. The steam generating boiler of claim 4 wherein the fuel inlet consists of a fuel tube extending horizontally along the width of the matrix means and comprises a plurality of holes for dispersing fuel. 6. The steam generating boiler of claim 5 wherein the plurality of holes for dispersing fuel are located in more than one axis. 7. The steam generation of claim 6 further comprising a plurality of cooing tubes located between the matrix means and the second oxidant inlet. 8. A steam generating boiler comprising, a combustion furnace having an inlet end, an outlet end, and further defined by a baffle wall and a plurality of furnace walls, wherein each of the furnace walls comprises a plurality of steam tubes aligned with the vertical length of the furnace wall and in fluid connection with a steam drum located on the opposite side of the baffle wall and downstream of the outlet end of the combustion furnace, a first oxidant inlet positioned near the inlet end of the combustion furnace for providing a first oxidant, a fuel inlet positioned near the inlet end of the combustion furnace for providing a fuel, a perforated plate consisting of a plurality of circular holes located upstream of the fuel inlet, a plurality of steam tubes attached to a wall of the combustion furnace, wherein the steam tubes are fluidly connected to a steam drum located downstream of the combustion chamber, a first matrix means consisting of fitted tiles having venture holes located downstream of the first oxidant inlet and the fuel inlet, wherein the outermost edges of the matrix means are free from contact with the furnace walls and the baffle plate, a second oxidant inlet for providing a second oxidant located downstream of the first matrix means, a second matrix means consisting of fitted tiles having venture holes located downstream of the second oxidant means. 9. The steam generating boiler of claim 8, further comprising an non-coiled inter-stage cooling tube located between the first matrix means and the second matrix means. 10. The steam generating boiler of claim 9, further comprising an igniter located between the first matrix means and the second matrix means.
