A method of online control of a slag-forming process of gasification of a carbonaceous solid fuel, especially coal, in a gasification reactor with supply of a gasifying agent and a moderator is provided. Certain embodiments relate to a gasification process for producing a product gas including carbon monoxide and hydrogen from a solid fuel, to a computer program for online control of the slag-forming gasification process, and to a plant for conducting a gasification process for producing a product gas including carbon monoxide and hydrogen from a solid fuel. Certain aspects of the invention combine an online solid fuel analysis with a process model in order to operate a gasification process for solid fuels by the feed-forward principle at the thermodynamically optimal operating point. The invention permits the establishment of the operating point in real time in order to react to rapid variations in the composition of the solid fuel. Certain embodiments also permit the complete automation of the gasification process.

Described is a plant and process for biomass treatment, where the plant is configured to actuate said process which comprises: —a step A of thermochemical treatment of transformation of a biomass into a carbonaceous solid, where this transformation involves treating the biomass at a treatment temperature of between 150° C. and 300° C. and at a treatment pressure of between 10 atm and 50 atm for 0.5-8 hours, in the presence of water, with accessory production of a treatment gas; —a step B of mixing the treatment gas with an auxiliary gas, to obtain operating gas; —a step C of thermochemical decomposition of the carbonaceous solid in an atmosphere consisting of the operating gas, where the thermochemical decomposition is suitable to obtain a combustible synthesis gas. step

A method of producing oil, gas, and ash fertilizer from a feedstock includes inputting the feedstock into a reaction chamber having a wall, and combusting the feedstock in the reaction chamber. An electrical current flow is induced between the reaction chamber wall and the feedstock so as to cause arcing in the feedstock within the reaction chamber. Ash reaction byproducts migrate downward through the reaction chamber onto ash support structure, which is substantially electrically isolated from the reaction chamber wall. Gas and liquid reaction byproducts migrate upward through the reaction chamber to an upper chamber by a partial vacuum in the upper chamber, and are evacuated therefrom. The oil and gas are then separated from the evacuated gas/liquid products, providing the oil and the gas products. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.

The invention includes mixing gas or solid particulate fuel in a conduit segment that houses a mixing chamber. Fuel is fed through a fuel inlet port into the mixing chamber. High velocity combustion air from a blower is forced into the mixing chamber through a restricted orifice that generates a suction pressure for drawing gas or solid particulate fuel into the mixing chamber. A combustion chamber supply conduit delivers fuel from the mixing chamber into a burner.

A gasifier system that combines the use of dirty fuels with clean fuels such as biomass. The heat created produces steam for the co-generation of mechanical power and electricity. The dirty fuels are converted in a gasifier or a pyrolyzer into various useful products that include syngas, heat, and oils. Syngas that is produced by the dirty fuels normally emits pollutants when combusted that require scrubbing. However, when the syngas is combusted into a biomass gasifier the dirty fuel emissions are scrubbed by being reformed into a much cleaner syngas/producer gas. Heat transferred from the dirty fuels gasifier/pyrolyzer syngas increases the efficiency of the clean fuels gasifier that results in increased amounts of steam for electricity/power production. In lieu of producing steam, the syngas from the clean fuel gasifier can be used to fuel an engine for power production. Other outputs from the clean-fuels gasifier include biochar and ash.
