A power-generation system having a combined heat and power plant and a fermentation plant has an electrolysis plant, which is connected by lines to both the combined heat and power plant and to the fermentation plant. This arrangement enables a method in which heat from a combined heat and power plant can be used for a fermentation plant and additionally heat from an electrolysis plant can be used for the fermentation plant, whilst the oxygen from the electrolysis plant is used for the combined heat and power plant.

The present invention relates to a method and a plant for treating carbon-containing waste that may comprise mineral fillers and/or potential contaminants.

This method comprises: preparing a molten glass bath at a temperature between 1100 C. and 1600 C.; loading the waste to be treated into said molten glass bath; injecting an oxidizer and optionally a fuel under pressure into said molten glass bath by means of at least one hose, one end of which is immersed in said bath, said oxidizer being introduced in a molar amount less than the molar amount of the carbon-containing compounds, thus causing combustion of said waste and generation of hot synthesis gases; implementing heat exchange between a heat-transfer fluid and the hot synthesis gases in conditions allowing simultaneous recovery of at least part of their heat energy and at least part of the heat energy released by their combustion, air being injected sequentially into said gases during said heat exchange to cause self-ignition of the mixture of said gases and air, each injection increasing the degree of combustion.

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

The description relates to controlling slagging and/or fouling in biomass burning furnaces. Combustion of such a biomass the fuel with air produces combustion gases containing sodium and/or potassium compositions, and the combustion gases are treated by contacting the combustion gases with kaolin and aluminum hydroxide. At least one of the kaolin and aluminum hydroxide can be introduced with the fuel, in a combustion chamber, with reburn fuel or with overfire air. For fuels also high in zinc and/or heavy metals, magnesium hydroxide is introduced into the combustion chamber or following heat exchangers.

The present invention is intended to provide a hybrid combustion apparatus using the pyrolysis of water and combustion air, in which a combustion chamber is defined by a double wall and divided into a primary combustion chamber configured to combust waste and a secondary combustion chamber configured to combust exhaust gas, and the size (diameter) of a combustion unit through which waste is configured to be different from that of the combustion chamber in which a flame is located, so that combustion temperature is further increased by introducing air, so that heated due to proximity to a flame, as combustion air, combustible waste is combusted at an ultrahigh temperature by pyrolyzing water and combustion air by means of a high combustion temperature, and so that complete combustion is achieved by increasing the time for which a flame stays within the combustion chamber, thereby discharging clean exhaust gas.

An incinerator comprising a cylindrical housing and a plurality of burners is provided. Each burner is oriented to emit gas at an upward and radially inward angle such that the burners collectively generate an upward, helical gas flow. A method for incinerating gas in a cylindrical housing is provided. Flowing gas through a first burner, oriented at an angle, generates an upward, helical gas flow within the cylindrical housing and draws a gas flow through a second burner.
