Abstract
Description
Beschreibung description
Die Erfindung betrifft einen Abfallverbrennungsofen zum Verbrennen von industriellen und sonstigen Abfällen.The invention relates to a waste incinerator for incineration of industrial and other waste.
Bekannt sind Abfaliverbrennungsöfen mit direkter 01- oder Gasbrennerbeheizung ir der Brenn- oder Schwelkammer. Bei diesen Verfahren, wird eine weitere Beheizung einer nachfolgenden Nachwerbrennungseinrichtung erforderlich. Die Energie der Nachverbrennungseinrichtung wird dabei ungenügend oder nur teilweise Sür die erforderliche Prozesswärme der Anlage ausgenutzt.Waste incinerators with direct oil or gas burner heating are known ir the combustion or smoldering chamber. In this process, there is a further heating a subsequent afterburning facility required. The energy of the post-combustion device is insufficient or only partially Sür the required process heat of the Plant used.
Aufgabe der Erfindung ist es vor allem, mit nur einer Öl-oder Gasbrennereinrichtung bei optimaler Nutzung der Müllenergie die Prozesswärme und Nachverbrennungstemperatur bei vergleichsweise einfachem Aufbau und durch kompakte Bauweise zu erzeugen.The main object of the invention is to use only one oil or gas burner device with optimal use of waste energy, the process heat and post-combustion temperature to be produced with a comparatively simple structure and a compact design.
Der erfindungsgemäße Aufbau der Anlage ist dadurch gekennzeichnet, daß eine Kammer zur Aufnahme der Abfälle eine Ausbrennzelle zur indirekten Beheizung umschließt. Die Temperatur der Ausbrennzelle ist durch eine modulierende Brennereinrichturlg gleichbleibend. Die Strahlungswärme der Trennzelle bewirkt den Schwel- und Brennprozess in der Kammer. Bei zunächst unterstöchiometrischer Verbrennung werden die Abfälle verschwelt und die entstehenden Gase der Brenneinrichtung zugeführt. Die modulierende Brennereinrichtung stellt sich leistungsmäßig automatisch auf die Schwelgasmenge ein. Abhängig vom Aufkommen der Schwelgasmenge, wird der Brennereinrichtung vorgewärmte Sekundärluft aus der nachfolgend beschriebenen Abgaskühlvorrichtung zugeführt.The structure of the system according to the invention is characterized by that a chamber for receiving the waste and a burnout cell for indirect heating encloses. The temperature of the burnout cell is controlled by a modulating burner device constant. The radiant heat of the separating cell causes the smoldering and burning process in the chamber. In the case of an initially substoichiometric incineration, the waste is carbonized and the resulting gases fed to the combustion device. The modulating The burner device automatically adjusts to the carbonization gas quantity in terms of output a. Depending on the amount of carbonization gas, the burner device is preheated Secondary air supplied from the exhaust gas cooling device described below.
Die aus der Ausbrennzelle austretenden, abgebrannten Abgase werden mittels einer anschließenden Abgasfördereinrichtung beschleunigt, wodurch die Ausbrennzelle und die Kammer im Unterdruckbereich gehalten werden.The burned off gases exiting the burnout cell are accelerated by means of a subsequent exhaust gas delivery device, whereby the burnout cell and the chamber are kept in the negative pressure range.
Die Ahgasfö rdereinrichtung bildet in zweifachsareise die Abgaskühlung. Einmal direkt durch die zugeführte Förderluft und einmal indirekt durch den umschließenden Mantel, den die Kühlluft durchfließt und dann vorgewärmt der Brennereinrichtung und Kammer als Sekundärluft zugeführt wird.The Ahgasfö rdeinrichtung forms the exhaust gas cooling in two trips. Once directly through the supplied conveying air and once indirectly through the surrounding air Jacket through which the cooling air flows and then preheated to the burner device and chamber is supplied as secondary air.
Beide Sekundärluftzuführungen sind mit einer Sekundärlijft-Mengensteuerung versehen.Both secondary air supplies are with a secondary air volume control Mistake.
Die Sekundärluft-Mengensteuerung zur Kammer bewirkt über die Betriebszeit der Anlage eine zunächst unterstöchiometrische Verbrennung die gegen Ende der Betriebszeit in eine stöchiometrische Verbrennung übergeht und einen Ausbrand der Abfallrückstände ermöglicht.The secondary air volume control to the chamber takes effect over the operating time of the system an initially substoichiometric combustion towards the end of the operating time passes into a stoichiometric combustion and a burnout of the waste residues enables.
