Abstract:
A process for producing a gas stream having fuel or heat value comprising:combusting a solid or liquid fuel in a pulse combustion device and creating a pulsating combustion stream and an acoustic pressure wave, the pulse combustion device operating at sub-stoichiometric conditions; communicating the pulsating combustion stream and acoustic pressure wave through a fluid channel, the fluid channel containing stream and being maintained under reducing conditions, over at least a section of the fluid channel, wherein organic components contained in the combustion stream undergo endothermic reaction to form hydrogen, the fluid channel including a first stage section and a second stage section, the reducing conditions being maintained in the second stage section, the first stage section having a first exit temperature and the second stage section having a second exit temperature, the first exit temperature being greater than the second exit temperature, the second exit temperature being less than about 1900Â° F.; injecting a sulfur capturing agent into the fluid channel, the sulfur capturing agent capturing sulfur contained in the pulsating combustion stream, the sulfur capturing agent also acoustically agglomerating with particles contained in the pulsating combustion stream; and filtering the combustion stream in order to remove agglomerated particles.
