The invention relates to an aftertreatment arrangement () for the aftertreatment of at least gases downstream of a fluidized bed gasification process, in particular downstream of an HTW gasifier () of a pressure-loaded fluidized bed gasification process, having a particle separation unit () which can be arranged downstream of the fluidized bed gasification process and upstream of a gas cooler () that can be used for the further aftertreatment of the gases, wherein the aftertreatment arrangement comprises an intermediate cooling unit () which can be arranged downstream of the fluidized bed gasification process and upstream of the particle separation unit (), having a return (B) for gasification steam (B) that can be coupled to the fluidized bed gasification process. Furthermore, the invention relates to a method for the aftertreatment of at least gases downstream of a fluidized bed gasification process as well as the use of an intermediate cooling unit.

Aftertreatment arrangement and method for the aftertreatment of at least gases downstream of a fluid bed gasification system, and logic unit and use

A process and device for the gasification of liquid or fine-grain solid fuel materials in a reactor is described. Synthesis gas is generated in a first reaction chamber arranged in the upper part of the reactor; feedstock is fed to the upper part. Liquid slag precipitates on its lateral walls. The lower side has a hole with a slag drop-off edge; generated synthesis gas can be withdrawn in downward direction and the liquid slag can drop off the edge. A second chamber delimited by a water film is located under the opening. A third chamber adjacent to the bottom of the second is fed with water. A water bath is adjacent the bottom of the third chamber. The synthesis gas is withdrawn from the pressure vessel in an area at the side or below the third chamber, but located above the water bath.

Gasification reactor and process for entrained-flow gasification

The invention relates to an oxygen lance that has at least three mutually coaxial pipes, each of which delimits at least one annular gap. The outermost pipe is designed to conduct superheated steam and has a steam supply point, the central pipe is designed as an annular gap, and the innermost pipe is designed to conduct oxygen at a temperature of no higher than 180&#xb0; C. and has an oxygen supply point. A temperature sensor is arranged within the innermost pipe, said temperature sensor extending to just in front of the opening of the innermost pipe. The innermost pipe tapers in the form of a nozzle before opening; the innermost pipe opens into the central pipe; and the opening of the central pipe protrudes farther relative to the opening of the outermost pipe.

Device and method for introducing oxygen into a pressurized fluidized-bed gasification process

Using a method and installation for separating acid components, dust and tar from hot gases of gasification installations, an economical method using a corresponding installation is to be created, which enables acid compounds HF, HCl, HS, dust and tar to be reliably separated in the highest possible temperature range. The aim is achieved in that the media flow leaving the gasification at above 700&#xb0; C. is fed with additives to a desulfurization process and subsequently to a combined cyclonehaving associated filter cartridgesin a common vessel, and the gas is withdrawn for further use downstream of the filter cartridges.

A synthesis gas (H+CO) that comes from a gasifier is supposed to be used in more efficient and optimal manner, particularly for generating electricity, whereby then, COthat occurs at the same time is supposed to be passed to storage. This is achieved in that&#x2014;the synthesis gas (H+CO) and oxygen (O) from an air separation system are combusted in a burner, and relaxed by way of a gas turbine (driving a generator), &#x2014;COis separated in the waste gas stream and passed to a compressor driven by the gas turbine, and&#x2014;passed to COstorage as compressed CO.

Method for use of the synthesis gas that comes from a gasifier

A process and device for the gasification of liquid or fine-grain solid fuel materials with the aid of oxygenous, gaseous gasification agents in a reactor is described. Liquid slag is separated on the walls of the reactor. The synthesis gas is generated in a first reaction chamber arranged in the upper part of the reactor and the feedstock is fed to the upper part. Liquid slag precipitates on its lateral walls, with free downflow and no solidification of the slag surface. The lower side has a hole with a slag drop-off edge, from which the generated synthesis gas can be withdrawn in downward direction and the liquid slag can drop off the edge. A second chamber which is delimited by a water film is located under the opening and used to keep the synthesis gas dry and cool. A third chamber is adjacent to the bottom of the second and fed with water to cool the synthesis gas. A water bath is adjacent the bottom of the third chamber and collects the slag particles already solidified and dropped off or those particles still in the liquid phase. The synthesis gas is withdrawn from the pressure vessel in an area below or on the side of the third chamber but in any case located above the water bath.

A process for the production, treatment and combustion of synthesis gas for the purpose of generating electric power is disclosed. The synthesis gas is produced from a solid, carbon-containing fuel with the aid of an oxygen-containing gas and treated by a slag-separating device and a device separating alkalis. Subsequently, the synthesis gas produced is fed to an expansion turbine where the pressure energy is used for generating power. On account of the treatment and separation of alkalis the expansion turbine is protected from corrosion and mechanical impact. The expanded synthesis gas is then burnt under pressure and the combustion is used in a combined-cycle process using a gas turbine, steam generator and steam turbine for generating power. The process thus has an increased efficiency. Apparatus for use of the process is also described.

Modified gas and steam turbine process with integrated coal gasification under pressure

In the case of a device for gasification of carbonaceous fuels, having a discharge for slags into a slag bath, a solution is supposed to be created with which the gasifier discharge opening is reliably kept at a temperature that guarantees that the slag will flow out. This is achieved in that the gasifier discharge opening () is equipped with a ceramic drip edge () that can be electrically heated.

Device for gasification of carbonaceous fuels

With a method and a system for treatment of a hot crude gas generated by an entrained flow gasification system, removal of the compounds that contain sulfur and carbon is supposed to be undertaken in such a manner that hot gas is made available for further use. This is achieved in that a desulfurization () follows the gasifier (), in series, in the flow path of the hot gas, followed by a solid separation (), whereby behind the solid separation (), a partial stream () of the gas is provided downstream by way of a water quench (), a Venturi scrubber (), a crude gas cooler (), as well as an HO separation () and a compressor (), the flow path () of which is passed back, cooled, into the circuit, behind the gasification () and ahead of the desulfurization system.
