Abstract
Es wird ein Verfahren zur kontinuierlichen Förderung von Brennstaub in einen Flugstromvergasungsreaktor vorgeschlagen. Dabei wird das Schleusungs- und Dosiersystem für den Brennstaub unmittelbar mit der Trocknungs- und Mahlanlage verbunden und der Brennstaub über eine längere Förderstrecke bis 500m nach dem Prinzip der Fließförderung dem Vergasungsreaktor zugeführt. Das System führt zu einer bedeutenden Senkung der Investkosten und zur Erhöhung der Sicherheit im heißen Vergasungsteil.A method for the continuous delivery of fuel dust into an entrained-flow gasification reactor is proposed. The sluice and dosing system for the fuel dust is directly connected to the drying and grinding system and the fuel dust is fed to the gasification reactor over a longer conveying distance of up to 500m according to the principle of flow promotion. The system leads to a significant reduction in investment costs and increased safety in the hot gasification section.
Description
Die Erfindung betrifft ein System zur kontinuierlichen Brennstaubeinspeisung in eine Flugstromvergasungsanlage bei Drücken bis 10 MPa zur Erzeugung eines CO- und H2- reichen Rohgases, das zu verschiedenen Synthesegasen, energetischen Gasen und Wasserstoff aufbereitet werden kann. Die Zuführung des Brennstaubes in das unter Druck stehende Vergasungssystem geschieht dabei durch Fließförderung einer Brennstaub- Trägergassuspension mit Förderdichten von 250–450 kg/m3. Eine umfangreiche Beschreibung der Technologie enthält die Patentschrift
Der Erfindung liegt die Aufgabe zugrunde, ein System zur kontinuierlichen Fließförderung einer Brennstaub-Trägergassuspension mit Förderdichten von 250–450 kg/m3 in eine Flugstromvergasungsanlage bei Drücken bis 10 MPa anzugeben, bei der die konstruktive Ausgestaltung eine erhebliche Reduzierung der Brand-gefährdeten Brennstaubmengen mit sich bringt. The invention has for its object to provide a system for continuous flow promotion of a Brennstaub carrier gas suspension with conveying densities of 250-450 kg / m 3 in an entrained flow gasification plant at pressures up to 10 MPa, in which the structural design of a significant reduction in fire-endangered Brennstaubmengen brings.
Die Aufgabe wird durch ein System mit den Merkmalen des 1. Anspruches gelöst. The object is achieved by a system having the features of the first claim.
Der Erfindung schafft eine Flugstromvergasungsanlage mit pneumatischer Brennstaubzuführung, bei der die mit einer erhöhten Brandgefährdung einhergehenden Brennstaubmengen im Bereich des heißgehenden Flugstromvergasers erheblich reduziert sind, wobei zum einen auch längere Transportwege zwischen Dosiergefäß und den Brennern des Vergasungsreaktors ohne weitere Zwischenstufen durch Fließförderung bei hohen Dichten zwischen 250 bis 450 kg/m3 überwunden werden und zum anderen der Bedarf an Fördergas über den Dünnstrom- und den Dichtstrombereich hinweg minimiert ist. The invention provides an entrainment gasification plant with pneumatic Brennstaubzuführung, in which the associated with an increased fire hazard Brennstdmengenmengen are significantly reduced in the hotgoing Flugstromvergasers, on the one hand longer transport routes between metering and the burners of the gasification without further intermediate stages by flow promotion at high densities between 250 be overcome to 450 kg / m 3 and on the other hand, the need for delivery gas over the Dünnstrom- and the Dichtstrombereich away is minimized.
