  • Publication number: 20070209642
    Abstract: A carburetion system and method for adapting a low-Btu gas source with a low-Btu gas consumer. Pressure-based air-gas mixers geometrically appropriate for the carburetion system and method. The carburetion system comprises a low-Btu gas inlet, a gas outlet, a zero-pressure regulator, and at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2:1. The method comprises diverting a low-Btu gas to a gas outlet when the gas consumer is off. The method further comprises, during operation of the consumer, diverting low-Btu gas to a zero-pressure regulator in order to balance low-Btu gas pressure with air pressure, passing low-Btu gas to at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2:1, mixing the low-Btu gas with air in the at least one pressure-based air-gas mixer to form an air-gas mixture, and sending the air-gas mixture to the consumer.

  • Patent number: 7077878
    Abstract: The aim of the invention is to provide a method for gasifying organic materials which is simple to carry out and requires minimal equipment and which produced an undiluted gas of high calorific value. The inventive method should eliminate the need to use fluid beds and heat exchangers with high temperatures on both sides, with the heat being transferred from the furnace to a heat-carrying medium in a particularly defined way. To this end, the feed material is divided into a volatile phase and a solid carbon-containing residue in the pyrolysis reactor by circulating a hot heat-carrying medium. After the reaction agent has been added, said volatile phase is converted into the product gas by further heating in the reaction area, also using the heat-carrying medium. The solid, carbon-containing residue is separated from the heat-carrying medium in the separating stage and burnt in the furnace.

  • Publication number: 20030005634
    Abstract: A method for producing clean energy from coal by feeding the coal in a reactor which is sealed to the atmosphere and moving the coal in the reactor while injecting oxygen to combust a portion of the coal in a substoichiometric mode to devolatilize the coal and yield a pressurized hydrogen rich raw gas which contains coal-derived cancer causing distillates and hydrocarbons together with a hot char. The distillates and the hydrocarbons are cracked to result in a cracked gas of essentially 2H2 and 1CO which after desulfurization becomes an ideal synthesis gas that can be synthesized to a liquid fuel for heating and transportation as an alternate to petroleum.

  • Patent number: 5707408
    Abstract: Production of fuel gas which generates little nitrogen oxides on combustion, has a prolonged combustion period for unit volume, and presents a high combustion temperature.Alcohol or other liquid fuel is burnt in a fuel layer 20 in a combustion chamber 18 to generate a primary fuel gas, which is mixed in a gas pipe 14 with pressurized air ejected by an air nozzle 16, where spiral flow of air is formed around the ejected air. The ratio of the cross section of the primary fuel gas flow to that of air ejected from the air nozzle 16 is first decreased and then increased, so that vortices are formed in the area where the cross section changes to react the primary fuel gas with air and decompose hydrocarbons in the primary fuel gas into carbon and hydrogen with high reactivity, thus producing a fuel gas capable of high temperature combustion with low amount of nitrogen oxides generated.
