Description

TECHNICAL AREA

The invention relates to a device and a method for HTW gasification of feedstocks and for providing the gasified feedstocks as a bottoms product and synthesis gas, with high reliability and optimized media management. In particular, the invention relates to an apparatus and a method according to the preamble of the respective independent claim.

BACKGROUND

The further development of the high temperature Winkler (HTW) coal gasification process, which is based on Winkler fluidized bed gasification, which was originally operated under ambient pressure, opens up possibilities for the HTW process also for generating synthesis gases (in particular for products of the petrochemical industry) or in combination Power plants to use for efficient and cost-effective power generation. Furthermore, the further development of HTW processes has already been promoted with regard to the gasification of biomass, domestic waste or hard coal with a high ash content.

In synthesis gas production, for example, the following gasification media are used, depending on the required quality of the synthesis gas: CO2, N2, O2, air, steam. The gasification media are injected at different levels.

With regard to the gasification media, different requirements are made. The feeding of the gasification media should be possible with the best possible uniform distribution in the gasification interior. The risk of nozzle burns should be kept as low as possible. In the case of preheated gasification media, a temperature which is as precisely as possible is desirable, in particular in order to avoid condensation.

The DE 34 39 404 C2 describes a nozzle for injecting gasification agent into a fluidized bed solid carburetor, which nozzle has a higher flow rate tube-in-tube arrangement in the outer tube.

By means of previously used arrangements, a simple, reliable media supply can not yet be realized in a satisfactory manner.

DESCRIPTION OF THE INVENTION

The object of the invention is to provide a device and a method with the features described above for reliable design of the HTW gasification process with optimized media management, whereby the simplest possible control of the fed into the HTW reaction chamber media can be achieved with high reliability.

This object is achieved by an HTW carburettor device set up for gasifying feedstocks and for providing the gasified feedstocks as a bottoms product BP and synthesis gas, having an HTW reaction space and a feedback system coupled thereto, adapted to recirculate media from the HTW reaction space, in particular from a freeboard zone FB , back into a fluidized bed zone WB the HTW reaction space, wherein a plurality of burners for introducing gasification media into the HTW reaction space open, which burners are arranged in at least one plane, wherein the HTW carburettor device has a control device configured to regulate the supply of burners with gasification media, said HTW carburetor device has at least one ring line arrangement in at least one of the levels, which ring line arrangement each comprises a plurality of burners, which are each coupled to a common loop for supplying the gasification media, wherein the control means a central gasification medium supply and a central Control unit is arranged for centrally controlling the supply of the majority of burners with gasification media via the loop. As a result, the media supply can be centrally controlled on the one hand, on the other hand, the supply can be done in a very simple manner in a very homogeneous manner. In particular, a predefined pulse strength can be ensured in a comparatively exact manner at the respective nozzle / burner.

The term burner can also be used to denote a nozzle for injecting medium without ignition of the medium.

As a result, the reliability can be further increased.

According to one embodiment, a plurality of common ring lines are arranged both below and above a return line of the feedback system. As a result, the advantageous effects over a large height section can be ensured, in particular both in the fluidized bed and in the freeboard zone.

According to one exemplary embodiment, the HTW reaction space has a freeboard zone which is greater by at least a factor of 1.5 to 14 than the fluidized bed zone. This also provides particular advantages in terms of the proportion of higher hydrocarbons in the synthesis gas.

According to one embodiment, the HTW reaction space formed by the fluidized bed zone and the freeboard zone extends over a height of at least 20m or at least 30m or up to 40m, the freeboard zone FB in the height direction is longer than the fluidized bed zone, and wherein the return system opens into the fluidized bed zone. According to one embodiment, the HTW carburettor device is pressure charged, in particular in the range 2 to 40 bar.
