Abstract
Description
Die Erfindung betrifft eine Sonde zur Überwachung der Flammen in einer Schmelzkammerfeuerung. Derartige Schmelzkammerfeuerungen werden zur Verbrennung oder zur Vergasung von Feststoffen im industriellen Maßstab eingesetzt.The The invention relates to a probe for monitoring the flames in a Slag tap. Such Schmelzkammerfeuerungen be for the combustion or gasification of solids in industrial environments scale used.
Gemäß den Sicherheitsbestimmungen
zu üblichen
industriellen Schmelzkammerfeuerungs-Anlagen ist es vorgeschrieben,
den Zustand der Flammen ständig
zu überwachen.
Nach herkömmlichem
Stand der Technik, wie er in der
Eine Flammenüberwachungssonde wird gewöhnlich nahe den Brennern in der Reaktorwand angebracht. Meistens hat eine Flammenüberwachungssonde einen Sensor in einem Schutzgehäuse, das den Sensor vor die Hitze schützt und worin ein Kühlmittel durchströmen kann. Dies ist notwendig, damit die Flammenüberwachungssonde in einer Feuerungskammer, worin die Temperatur bis zu 1600°C herrscht, nicht durch die Hitze zerstört wird. Um das Eindringen heißer Gase, geschmolzener Partikel oder Verunreinigungen auszuschließen, wird der Innenraum der Sonde um den Sensor mit einem Inertgas beispielhaft Stickstoff durchströmt. Das ausströmende Gas bildet einen Freistrahl in der Feuerungskammer, der das umgebende heiße Gas mit Partikeln ansaugt und mitreißt, dabei werden die Partikeln bis unterhalb der Erstarrungstemperatur abgekühlt. Das angesaugte Gas strömt auch entlang der Mündung der Sonde, wobei einige Partikel die gekühlte Mündung berühren, daran haften bleiben und erstarren. Auf dem Mündungsbereich der Sonde lagern sich zuerst die erstarrten Partikeln ab, die mit der Zeit einen langen Schlackerüssel entlang dem Spülgas-Freistrahl bilden. Der Rüssel wird von innen durch das Spülgas gekühlt, wodurch seine Temperatur unterhalb der Schmelztemperatur der Partikel liegt und er nicht abgeschmolzen wird. Durch die Schwerkraft biegt sich dieser Schlackerüssel und versperrt dadurch die Sicht zu den Flammen der Brenner, es findet keine Überwachung statt, die Überwachungssonde kann keine Signale weiterleiten. Dies führt zur Unterbrechung der Produktion.A Flame detection probe becomes ordinary mounted near the burners in the reactor wall. Mostly one has Flame detection probe a sensor in a protective housing, which protects the sensor from the heat and wherein a coolant flow through can. This is necessary to allow the flame monitoring probe in a firing chamber, wherein the temperature is up to 1600 ° C prevails, not destroyed by the heat. To penetrate hot Gases, molten particles or impurities to exclude, the Interior of the probe around the sensor with an inert gas by way of example Nitrogen flows through it. The outflowing Gas forms a free jet in the firebox surrounding the surrounding name is Gas with particles sucks and entrains, thereby becoming the particles cooled to below the solidification temperature. The sucked gas also flows along the estuary The probe, with some particles touching the cooled mouth, stick to it and freeze. At the mouth area The probe first deposits the solidified particles that are mixed with the Time a long slob along the purge gas free jet form. The trunk is from the inside through the purge gas cooled, whereby its temperature is below the melting temperature of the particles and he is not melted down. By gravity bends this sissy and thereby obstructs the view to the flames of the burners, it finds no surveillance instead, the monitoring probe can not forward signals. This leads to the interruption of production.
Der Erfindung liegt daher das Ziel zugrunde, eine Flammenüberwachungssonde für die Schmelzkammerfeuerung bereitzustellen, mit der das obengenannte Problem nicht auftritt.Of the The invention is therefore based on the object, a flame monitoring probe for the To provide Schmelzkammerfeuerung, with the above Problem does not occur.
Die Aufgabe wird dadurch gelöst, dass die Flammenüberwachungssonde für eine Schmelzkammerfeuerung folgenden Merkmale aufweist:
- • unmittelbar um den UV/IR-Sensor ein Rohr konzentrisch angeordnet ist,
- • das konzentrisch um den UV/IR-Sensor angeordnete Schutzgehäuse eine sich aufweitende Mündung aufweist,
- • zwischen dem Rohr und dem Schutzgehäuse ein Dralleinsatz angebracht ist,
- • das Spülgas im Zentrum der Flammenüberwachungssonde den UV/IR-Sensor unverdrallt umströmen kann,
- • das Spülgas zwischen dem Rohr und dem Schutzgehäuse mit aufgeweiteter Mündungsoberfläche den Dralleinsatz durchströmen kann, wobei es verdrallt wird.
- • a pipe is arranged concentrically around the UV / IR sensor,
- The protective housing arranged concentrically around the UV / IR sensor has a widening mouth,
- • a swirl insert is fitted between the pipe and the protective housing,
- The flushing gas in the center of the flame monitoring probe can flow around the UV / IR sensor in an untwisted manner,
- • The purge gas between the pipe and the protective housing with flared mouth surface can flow through the swirl insert, whereby it is twisted.
Die Flammenüberwachungssonde für eine Schmelzkammerfeuerung ist eine optische Flammenüberwachungssonde mit einem Ultraviolett- oder Infrarot-Sensor (UV/IR-Sensor). Um den UV/IR-Sensor ist erfindungsgemäß ein konzentrisch angeordnetes Rohr angeordnet. Ein außen angeordnetes Schutzgehäuse, welches als Hitzeschild für den UV/IR-Sensor dient, weist eine sich aufweitende Mündung auf. Zwischen dem Rohr und dem Schutzgehäuse ist ein Dralleinsatz angebracht. Um den UV/IR-Sensor herum kann ein Spülgas unverdrallt strömen, durch den Dralleinsatz kann auch ein Spülgas durchströmen, wobei es verdrallt wird.The Flame detection probe for a melting chamber firing is an optical flame monitoring probe with an ultraviolet or infrared sensor (UV / IR sensor). To the UV / IR sensor is a concentric according to the invention arranged arranged pipe. An externally arranged protective housing, which as a heat shield for the UV / IR sensor is used, has a widening mouth. Between the pipe and the protective housing a swirl insert is attached. Around the UV / IR sensor around a purge gas can flow untwisted, through the swirl insert can also flow through a purge gas, wherein it is twisted.
Als Verwendung der Erfindung ist vorgesehen, dass der UV/IR-Sensor die freie Sicht zur Überwachung der Flammen bekommt, durch den unverdrallten Freistrahl des Spülgases im Zentrum der Sonde. Das verdrallte Spülgas breitet sich aus entlang der Mündungsoberfläche und verhindert die Anbackungen auf dem Mündungsbereich der Sonde, und das mit hoher Energie durchströmende Spülgas bildet einen Schutzschild vor dem UV/IR-Sensor.When Use of the invention is provided that the UV / IR sensor the free view to the monitoring the flames get, through the untwisted free jet of purge gas in the Center of the probe. The twisted purge gas spreads out along the mouth surface and prevents the caking on the mouth area of the probe, and the high energy flowing through Purging gas forms a protective shield in front of the UV / IR sensor.
In weiteren Verwendungen der Erfindung ist vorgesehen, dass die Flammenüberwachungssonde für alle Arten der Feuerung der Festbrennstoffe und die Vergasung für Kohle und andere Festbrennstoffe eingesetzt wird.In Further uses of the invention is that the flame monitoring probe for all types the firing of solid fuels and the gasification of coal and other solid fuels is used.
