Abstract: A gasifier system and process comprises a pulse combustion device in communication with a fluid channel for producing a gas stream having heat or fuel value. The pulse combustion device is operated under sub-stoichiometric conditions such that combustion and steam reforming both occur in the fluid channel. The pulse combustion device also produces a pulsating combustion product stream and an acoustic pressure wave. The acoustic pressure wave serves to cause agglomeration of particles contained within the combustion stream for easy removal. In one embodiment, a sulfur capturing agent is injected into the fluid channel for not only removing sulfur from the combustion product stream but for also facilitating particle agglomeration. Ultimately, a gas stream containing hydrogen is produced that may be used in various processes, such as in the production of electricity.

The two-stage cleaning of the stream of waste gas includes a dust collection unit and an adsorption unit. The waste heat is recycled through a heat exchanger to generate heat and electricity.

Abstract: A steam-generating combustion system includes an oxygen enriched gas provided as at least part of an oxidant stream. A combustion chamber receives and combusts a fuel in the oxidant stream and generate steam. The combustion chamber generates flue gas having a flue gas volume which is smaller than a volume of flue gas generated by the combustion chamber when operated with air as the oxidant stream. A flue gas pollutant control system receives the flue gas from the combustion chamber and reduces at least one of particulate matter, SOx, NOx, and mercury. The reduction in flue gas volume allows the implementation of much smaller pollutant control equipment, since the size of the pollutant control units is mainly based on the volume or mass flow rate of flue gas to be treated. Moreover, the system including oxygen-enriched gas in the oxidant will lead to concentrated levels of the pollutants in the flue gas.

Abstract: The methods and systems of the present invention reduce NOx emissions in combustion systems, e.g., power plants, boilers, furnaces, incinerators, engines, and any combinations thereof. The inventive process decreases NOx emissions from stationary combustion sources and provides improved utilization of low-grade biomass and other waste fuels without slagging and fouling problems. The invention reduces NOx emissions while utilizing gasified fuels, including biomass and low-grade waste fuels, by gasifying solid fuels and injecting produced gas into a reburning zone of, for example, a boiler at relatively low temperatures and in relatively small amounts. By feeding the gas directly into a reburning zone, the need for gas cleaning is eliminated or substantially reduced as tars are burned in the flame and alkali species may be present at much lower levels than is the case with direct combustion applications.

Abstract: A solid-waste conversion plant produces useful products and electrical energy in a closed system with zero emission of pollutants into the atmosphere. The plant is characterized by catalytic ionic-impact chambers having a pair of electrodes that establish an electric arc. The electric arc breaks down solid waste molecules into a plasma of atomic constituents which exothermically recombine into simple molecules upon leaving the plasma. A primary chamber converts carbon-based waste into solidifiable metal, sulfur and glassy slag extractable from the bottom of the chamber, and into gas containing CO, H2, and CH4. A second chamber contains high carbon waste input that is converted by the arc into incandescent coke, which converts CO2 and H2O in the gas from the first chamber into more CO, H2 and CH4, thereby forming a fuel gas. The fuel gas is combusted in gas turbine generators to produce electricity for operating the electric arcs, plus a sellable surplus.
