Abstract: In one embodiment, a method for generating heat energy includes injecting a stream having a concentration of at least 50% oxygen (O2 stream) into a primary gas stream through a mixer, the mixer discharging the O2 stream as two or more spaced jets traversing the primary stream, thereby enriching the primary gas stream. The method further includes mixing fuel with the enriched primary gas stream, thereby forming a fuel stream; and combusting the fuel stream, thereby forming a flue gas stream.

Abstract: An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to remove sulfur, a first and second pre-reformers configured to pre-reform a process gas and fuel gas, respectively, a first and second heat exchangers configured to dry and heat the pre-reformed fuel gas, respectively, and a reformer configured to produce a syngas and flue gas. The method includes using a process stream selected from the group consisting of air, PSA off-gas, hydrocarbon gas, and combinations thereof to dry the fuel gas and using a process stream selected from the group consisting of the flue gas, the syngas, and combinations thereof to heat the dry fuel gas. The second pre-reformer is a low-pressure pre-reformer, so that the heat contents of the fuel gas is increased through converting heavy hydrocarbons in the fuel gas to CO and H 2 by the second pre-reformer.

Abstract: A method and apparatus for optimizing boilers with high flue gas recirculation rate based with laser based diagnostic technology. A tunable diode laser is emitted from a launcher, is altered by the absorption spectra of the gas species that it intersects, and encounters a receiver.
