Description
Vorschubfeuerung mit an der Stirn- und Rückwand oberhalb des Rostes vorgesehenen Düsen ' zum Ansaugen und Einblasen von Rauchgasen oder Luft Es ist bei Vorschubfeuerungen bekannt, Brenngase aus dem Feuerraum abzusaugen und an anderen Stellen der Feuerung wieder zuzuleiten. Weiter ist es bekannt, in den Feuerraum an der Stirn- und Rückwand oberhalb des Rostes Verbrennungsluft oder Rauchgase einzublasen,, um -eine gleichmäßige Temperaturverteilung sowie eine Druckregelung im Brennraum zu erreichen.Advance firing with on the front and rear wall above the grate provided nozzles' for sucking in and blowing in smoke gases or air It is known in the case of advancing firing systems to suck fuel gases out of the furnace and to others Place the furnace back on. It is also known in the firebox to blow in combustion air or smoke gases on the front and rear wall above the grate, to -a uniform temperature distribution and pressure control in the combustion chamber to reach.
Je nach der zu verfeuernden Kohle ist es zur Erzielung einer guten Verbrennung erforderlich den- Feuerraum von` der Rückwand öder von der Stirnwand aus oder beiderseits gleichzeitig zu geblasen. Um dies mit Hilfe eines. einzigen. Gebläses durchzuführen, ist bei der den Gegenstand der Erfindung bildenden Vorschubfeuerung die Saugleitung des Gebläses, durch welche die Brenngase, gegebenenfalls unter Beimischung von Luft, aus dem Vorderteil des Feuerraumes angesaugt und durch die Düsen der Feuerraumrückwand zurückgeleitet werden, mit .einer absperrbaren Zweigleitung verbunden, welche durch Einstellen der Absperrglieder ein Einblasen von Druckluft sowohl durch die Düsen der Stirnwand als auch der Rückwand ermöglicht.Depending on the coal to be burned, it is necessary to obtain a good one Combustion required the combustion chamber from the rear wall or from the front wall blown from or both sides at the same time. To do this with the help of a. single. Perform blower is in the feed firing forming the subject of the invention the suction line of the blower, through which the fuel gases, possibly with admixture of air, sucked in from the front part of the combustion chamber and through the nozzles on the rear wall of the combustion chamber are fed back, connected to a lockable branch line, which through Adjustment of the shut-off elements is an injection of compressed air through both the nozzles the front wall as well as the rear wall allows.
Eine gemäß der Erfindung ausgebildete Wanderrostfeuerung ist in der Zeichnung in vereinfachter Darstellung beispielsweise veranschaulicht.A traveling grate designed according to the invention is in the Drawing illustrated in a simplified representation, for example.
Der Brennraum i wird mittels des WanderrosteS z beheizt, dem die Kohle durch den Trichter 3 unter dem Regelschieber 4 zugeführt wird und der unter dem Stauer 5 hinweg die Rückstände abführt. An der Stirnwand und an der Rückwand des Brennraumes sind Düsen 9, 13 angeordnet, Nvelche durch Verbindungsstücke 8, 12 an eine Rohrleitung 7, 11 angeschlossen und mit absperrbaren Schau- und- Reinigungsöffnungen versehen sind. In die mit Absperrmitteln 7' und i i' versehene Rohrleitung ist ein Gebläse 6 eingeschaltet, das noch mit einem absperrbaren Saugstutzen 16 und einer absperrbaren Zweigleitung 15 verbunden ist.The combustion chamber i is heated by means of the traveling grate z, to which the coal is fed through the funnel 3 under the control slide 4 and which removes the residues under the stevedore 5. Nozzles 9, 13 are arranged on the front wall and on the rear wall of the combustion chamber; In which is provided with shut-off means 7 'and ii' pipe, a fan 6 is switched on, which is still connected with a closable suction nozzle 1 6 and a closable branch line 15 °.
Ist das Absperrglied 7' geöffnet, das Absperrglied 15' und-16' in der Zweigleitung und dem Saugstutzen dagegen geschlossen, so saugt das Gebläse durch die Düsen 9 und das Rohr 8 Gase aus dem Feuerraum an. Die Gase bestehen aus einer Mischung von Feuergas und Luft, welche durch die -regelbaren öffnungen io einströmt. Dieses Gemisch -wird von dem Gebläse 6 durch die Leitung i i in das Rohrstück 1 2 gedrückt, aus welchem es durch die Düsen 13 iiz der Rückwand des Feuerraumes. in. die Flamme eingeblasen wird.If the shut-off member 7 'is open, the shut-off member 15' and -16 'in the branch line and the suction port, however, are closed, so the fan sucks through the nozzles 9 and the pipe 8 gases from the combustion chamber. The gases consist of one Mixture of fire gas and air, which flows in through the adjustable openings. This mixture is fed into the pipe section 1 by the fan 6 through the line i i 2 pressed, from which it is through the nozzles 13 iiz the rear wall of the furnace. in. the flame is blown.
Ist das Absperrmittel 7' geschlossen, so kann die Stirn--und-Rückwand der Feuerung mit der durch Stutzen 16 angesaugten Luft bestrichen werden. Die Absperrvorrichtungen dienen zugleich zur Regelung der Luft- und Gasmenge. Es können auch die Düsenquerschnitte regelbar sein.If the shut-off means 7 'is closed, the front and rear walls the furnace can be smeared with the air sucked in through nozzle 16. The shut-off devices also serve to regulate the amount of air and gas. The nozzle cross-sections can also be used be controllable.
