A method for entrained bed gasification of biomass is provided, wherein pure biomass is first torrefied then milled and the torrefied and milled biomass is introduced to the gasification process with a fluid as a slurry. An energetically favorable process is described using the combination of torrefaction, milling and mixing with a liquid, preferably residual products from a subsequent synthesis process, but also other available suitable materials.

A method for calibrating a dust load flow measuring system is provided. The dust delivery line may be connected from a metering vessel to a calibration line leading to the input sluice in the delivery direction downstream of the installed dust load flow measuring device instead of to the gasification reactor. The input sluice is provided with a weighing unit such that the weight of the content of the input sluice is determined. A differential pressure that may be set is controlled between the metering vessel and the input sluice, the dust load flow is determined in a time interval.

A gas and steam turbine plant includes a waste-heat steam generator which is located downstream of a gas turbine on the flue-gas side and which has heating surfaces that are connected into a water/steam circuit of a steam turbine. A gasification device is located upstream of a combustion chamber of the gas turbine through a fuel line, for the integrated gasification of a fossil fuel. The gas and steam turbine plant is to be operated with particularly high plant efficiency even when oil is used as the fossil fuel. Thus, a heat exchanger is connected on the primary side into the fuel line upstream of a mixing apparatus for admixing nitrogen to the gasified fuel, as seen in the direction of flow of the gasified fuel. The heat exchanger is constructed on the secondary side as an evaporator for a flow medium.

A pressure filtration system for cleaning residual quenching water of a gasifying device that gasifies carbon-containing fuels under elevated pressure is provided. The soot water from the quencher is passed to a filter system, which has pressure filter chambers operating alternately in filtering mode under gasifying pressure or in cleaning mode. The filtrate from these chambers is passed to a quenching water reservoir, from which the quencher is fed with quenching water. Only small temperature and pressure losses with respect to the residual quenching water leaving, and only a small additional amount of energy has to be expended to overcome the remaining pressure difference to bring the filtrate that is to be returned back to the gasifying pressure. The residual quenching water is cleaned substantially under gasifying pressure in a pressure filter, avoids flash evaporation of the residual quenching water into the vacuum area, with vapour cooling and a subsequent increase in pressure and reheating.
摘要:
A chemical reactor of a technical plant, in particular a power plant system is provided. The chemical reactor includes a gas-tight wall forming a gas channel, wherein heat exchanger surfaces that are permeable with a first fluid and at least partially include a catalytically active surface are located in the gas channel. A method for converting CO using such a reactor is also provided.

The invention relates to a method for starting a burner for combusting synthesis gases, wherein said burner comprises first and second fuel passages, the first fuel passage encompasses the second fuel passage in a substantially concentric manner and the gas transferred to the burner is mixed with combusting air and is combusted. According to said invention, in order to start the burner, the second fuel passage is first loaded with a synthesis gas to a predefined burner power at a first starting phase and the first fuel passage is loaded with the synthesis gas at a second starting phase.
