Description

Method and device for gasifying fuels with extraction Water vapor-free, tar-rich gases in the ring gas generator. There are gas generating plants known, in which several chambers are connected to one another in such a way that the gases and vapors from one or more later fueled (younger) chambers sent through the glowing layer of an already burnt out (older) chamber will. In these known systems, those developed in the younger chambers were developed Most of the tar vapors decomposed in the embers of the older chambers.

The present invention relates to a method and a device for the gasification of mineral) geliencleri fuels, especially of slag- and water-rich lzoli coals, oil slates and others for the purpose of generating gases that are as free of steam as possible and possible recovery of the tarry components expelled during the degassing. The fresh shipment must therefore be protected from overheating and its consequences. Only a part of the hot gases rising from the gasification layer of the younger chambers is to be used for drying and desulfurization, which are favorable for this. Establish and extend heat levels in order to separate the water vapor from the tar vapors and to bring the latter to develop in a liöclist manner. For dividing the hot gases is a further Kanalv "rbindung the Ringkaniinern above the encryption g ga # sting layer is required, so that the chambers in two ways may be connected as a ring.

Between the known upper (0) and lower (U) connecting channels a new closable connecting channel - intermediate channel Z_ - is attached, which is connected to a suction device and a part of the rising gases over should divide the gasification layer. The one separated part becomes an older one Chamber fed and discharged through its lower connecting channel rc, the other The part remaining in the chamber depends on the condition of the fuel added led different ways.

First of all, during the drying process, it is loaded with fresh liiiidurcligesaugt and also with the water vapors through the upper connecting channel fed and discharged to an older chamber, and then it is during the desulfurization through the dried charge with the smoldering products via the tar separator derived.

The operation and circuit of a for gasifying wet fuels The necessary three-bucket double ring gas generator is more important: The lockable one Discharge lines for tar gases and hot gases as well as the lockable intermediate (Z) and upper (0) connecting channels together (see figure) are connected with suction cups. The older chamber for hot gases is connected to its gas exhaust pipe; the top (0) and the intermediate channels 7_ are closed, the lower ones (L..T) like everything went other chambers always open. The youngest (drying) chamber is from the gas train lines completed, switched on with the upper (0) and with the intermediate channel Z in the ring. The younger (smoldering) chamber is connected to the smoldering gas line and with the Intermediate channel Z switched on in the ring, the upper connection channel 0 is closed. The switching of the chamber continues when the hot gas chamber is recharged away.

In the drying chamber, the negative pressure in the intermediate channel gives the pressure ratio to the upper canal by throttling the latter down: when the smoldering chamber is the ratio of the negative pressure of the threshold line to that of the intermediate channel around the to coordinate the most favorable division of the hot gas flow for each type of fuel.

The connection is sufficient for fuels that do not require drying two chambers; for fuels that are particularly rich in water, four chambers can become one Ring can be connected to the water vapor in two hot gas chambers - which also, like in every other case, used to obtain aminonia "= being able to earth - permanently and to make it usable.

The processes of the ring gas generator can also be used in the double ring gas generator are executed.

Claims (1)

PATENT CLAIMS: i. A method for gasifying fuels with the production of steam-free, tar-rich gases in the ring gas generator, characterized in that the hot gas flow rising in a known manner from the gasification layer of the younger chambers is divided and one part is passed through an older chamber, the other part initially during drying with the fresh fuel and the absorbed water vapors is also passed through the older chamber and then during the desulfurization with the carbonization products to the carbonization gas line. a. Ring gas generator for carrying out the method according to Claim i, characterized in that closable intermediate channels (Z) are attached between the upper and lower connecting channels (0 and U) of the ring generator.
