Abstract

The invention concerns a process for dressing brown coal for combined gas and steam processes in heat-generating installations. The aim of the invention is to achieve substantial reduction of the CO2 emission per useful effect unit by reduced use of fossil energy carriers; the devices for drying raw brown coal are to be connected to the heat-generating installation in such a manner that the energy of the exhaust vapours is fully utilized. To this end, the drying container is operated in conjunction with a pressurized fluidized bed combustor, a gas turbine, a steam turbine, a pneumatically heated steam intermediate heater and a waste heat boiler; the drying energy for the drying container is obtained from saturated steam from the waste heat boiler of the combined process; the energy content of the de-dusted exhaust vapours under medium pressure is used to evaporate a partial flow of feed water; the gas turbine is operated with exhaust gases from the pressurized fluidized bed combustor; condensed combustion air is used for intermediate superheating of the steam, with cooling of the combustion air; and the exhaust vapour condensate formed by energetic connection is prepared and used to supply water for the circulation process.

Description

Die Erfindung betrifft ein Verfahren zur Braunkohlenaufbe­ reitung für Gas-Dampf-Kombiprozesse einer Wärmeerzeugungs­ anlage.The invention relates to a method for lignite mining for gas-steam combination processes for heat generation investment.

Bekannt ist eine Anordnung zur Vorstrom-Rohkohletrocknung für Kondensationskraftwerke, wobei die Brüdenkondensations­ wärme vollständig ausgenutzt und weder eine Brüdenrückverdichtung noch eine separate elektrische Brüdenentstaubung stattfindet, und die Trocknung in einem mit Membranrohr­ wänden als Heizflächen versehenen und mit Anzapfdampf als Heizdampf von der Hauptturbine versorgten Schüttungsschacht durchgeführt und der dabei entstandene Brüden beim Aus­ tritt in den Brüdenkanal - also beim Verlassen des Trockners - mittels dampfabreinigbarer Filterwand entstaubt wird (DD-PS 2 81 237). Im 2 81 237 wird die Brüdenenergie als Se­ kundärenergie vollständig nur durch Aufteilung in mehrere und qualitativ unterschiedliche Einsatzfälle genutzt, was eine aufwendige Einbindung in das Anlagengesamtkonzept be­ dingt. Außerdem ist diese Schaltungsanordnung ausschließlich auf einen Kraftwerksblock bezogen, der die Stromerzeugung nur im "reinen" Kondensationsbetrieb durchführt.An arrangement for pre-current raw coal drying is known for condensation power plants, the vapor condensation heat fully exploited and neither vapor recompression a separate electrical vapor dedusting system takes place, and drying in a membrane tube walls as heating surfaces and with tap steam as Heating steam from the main turbine supplied filling shaft carried out and the resulting brothers when leaving enters the vapor channel - i.e. when leaving the dryer - is dedusted by means of a steam-cleanable filter wall (DD-PS 2 81 237). In 2 81 237 the vapor energy is called Se secondary energy only by dividing it into several and qualitatively different applications, what a complex integration into the overall system concept things. In addition, this circuit arrangement is exclusive related to a power plant block that generates electricity only in "pure" condensation mode.

Weiterhin bekannt ist ein Verfahren zum Betreiben eines Gas-Dampf-Kombiprozesses (DE-OS 39 07 217). Das Verfahren gliedert sich in zwei technologische Konzepte, wobei das in Fig. 1 gezeigte Konzept den Betrieb der Vorschalt-Gas­ turbine mit Erdgas beinhaltet. Diese Lösung ist trivial und seit Jahren in kommerzieller Nutzung. Das zweite und in Fig. 2 gezeigte Konzept schließt eine Druckwirbelschicht- Kohlevergasung eines Kohleteilstromes ein. Da der Kohleteil­ stromvergasung noch eine Dampf-Wirbelschicht-Trocknung vor­ geschaltet ist und diese Trocknung nicht im energetischen Verbund mit dem Kombiblock steht, muß diese mit elektro­ energieintensiver Brüdenrückverdichtung und externem Brüden­ entstauber betrieben werden, so daß dieses Blockkonzept einen niedrigen Wirkungsgrad von 42-44% hat. Der anlagentech­ nische Aufwand ist sehr groß, da neben der typischen Kom­ biblockausstattung zusätzlich eine Gasturbinenanlage, eine Zwischenkühlung von Luft, verbindende Rohrleitungen und Kanäle, ein druckaufgeladener Wirbelschicht-Vergasungsre­ aktor mit zugehörigem Heißgasentstauber und eine elektro­ energieverbrauchende Trocknungstechnologie (ohne energe­ tischen Verbund mit dem Kombiblock) notwendig werden.Also known is a method for operating a gas-steam combination process (DE-OS 39 07 217). The method is divided into two technological concepts, the concept shown in FIG. 1 including the operation of the ballast gas turbine with natural gas. This solution is trivial and has been in commercial use for years. The second concept, shown in FIG. 2, includes pressure fluidized bed coal gasification of a coal partial stream. Since the coal part of the gasification of the electricity is still a steam fluidized bed drying and this drying is not energetically linked to the combi block, this must be operated with electro-intensive vapor recompression and external vapor, so that this block concept has a low efficiency of 42-44 % Has. The system engineering effort is very high, because in addition to the typical combi block equipment, there is also a gas turbine system, intercooling of air, connecting pipes and ducts, a pressure-charged fluidized bed gasification reactor with associated hot gas deduster and an electro-energy-consuming drying technology (without an energetic connection with the combi block ) become necessary.

Der Erfindung liegt die Aufgabe zugrunde, eine deutliche Reduzierung der CO2-Emission je Nutzleistungseinheit durch verringerten Einsatz fossiler Energieträger zu erreichen, wobei die Trocknungseinrichtungen für Rohbraunkohle so mit der Wärmeerzeugungsanlage verbunden werden, daß eine voll­ ständige energetische Verwertung des Brüdens realisiert wird.The invention has for its object to achieve a significant reduction in CO 2 emissions per unit of power by reducing the use of fossil fuels, the drying facilities for raw lignite are connected to the heat generation system so that a full energy recovery of the vapor is realized.
