Description
Kesselfeuerung zur Verbrennung von Müll, insbesondere von feuchtera MuilBoiler firing for the incineration of waste, especially of feuchtera Muil
Die Erfindung betrifft eine Kesselfeuerung zur Verbrennung von Miill, insbe-sondere feuchtem Müll, die mit einem Verbrennungsrost und einem vorgescfral-teten Müllaufgaberost versehen ist, wobei die Unterwindzonen des Verbren-nungsrostes mit vorgewärmter Luft und die des Müllaufgaberostes mit rezir-kuliertem Rauchgas beaufschlagt sind.The invention relates to a boiler firing system for the combustion of waste, in particular moist waste, which is provided with a combustion grate and a pre-scrubbed garbage grate, the underwind zones of the combustion grate being exposed to preheated air and those of the garbage grate being subjected to recirculated flue gas .
Aus der Literatur ist bekannt, daß die Dioxin- und Furanemissionen bei feuchtem Miill wesentlich höher als bei trockenem Müll sind.It is known from the literature that the dioxin and furan emissions are much higher in the case of a damp mine than in the case of dry waste.
Durch die DE 39 13 885 Al ist eine Kesselfeuerung zum Verfeuern feuchter Brennstoffe bekannt geworden, die mit einem Feuerungsrost und einer zu-geordneten Einrichtung zum Vortrocknen der Brennstoffe versehen ist. Bei dieser bekannten Feuerung wurde der Feuerungsrost zur Brennstoffaufgabe hin verlängert und dient vor dem Feuerraum als Trocknungsrost für den feuchten Brennstoff. Für die Trocknung wurden die Unterwindzonen des Trocknungs-rostes, einstellbar mit Rauchgas oder vorgewärmter Luft, beaufschlagt.From DE 39 13 885 Al a boiler firing for burning moist fuels has become known, which is provided with a firing grate and an associated device for predrying the fuels. In this known furnace, the furnace grate has been extended for the fuel feed and serves as a drying grate for the moist fuel in front of the furnace. For the drying, the underwind zones of the drying grate, adjustable with flue gas or preheated air, were applied.
Durch die DE 39 13 886 Al ist ein Verfahren zur Minderung der Emissionen und zur Optimierung der Feuerführung bei einer Rostfeuerung durch Rezirku-lation der Rauchgase bekannt geworden, bei dem die Rauchgase den vorderen Unterwindzonen und/oder der Hauptluftzonen und/oder den hinteren Unterwindzonen dosiert zugeführt werden.DE 39 13 886 A1 discloses a method for reducing emissions and optimizing fire control in grate firing by recirculating the flue gases, in which the flue gases meter the front underwind zones and / or the main air zones and / or the rear underwind zones be fed.
Nachteilig bei den bekannten Anlagen ist der lange und daher sehr aufwen-dige Rauchgasweg vom kalten Ende des Kessels bis zum Rost.A disadvantage of the known systems is the long and therefore very complex flue gas path from the cold end of the boiler to the grate.
Aufgabe der Erfindung ist, eine Kesselfeuerung für die Verbrennung von Müll, insbesondere feuchtem Müll, zu schaffen, die eine einfache, kostengunstige Konstruktion aufweist und die Anforderung für eine schadstoffarme Verbrennung des feuchten Mulls erfüllt.The object of the invention is to provide a boiler firing for the combustion of waste, in particular wet waste, which has a simple, inexpensive construction and meets the requirement for low-pollution combustion of the wet garbage.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelost. Eine alternative Ausgestaltung der Erfindung ist in dem Unteranspruch angegeben.This object is achieved by the characterizing features of claim 1. An alternative embodiment of the invention is specified in the subclaim.
Durch die erfindungsgemäßen Maßnahmen werden die folgenden Vorteile er- · zielt:The following advantages are achieved by the measures according to the invention:
Der Ausstoß, besonders von Dioxinen, Furanen, CO, N0X und Cx Hy, wird vermindert.The emissions, especially of dioxins, furans, CO, N0X and Cx Hy, are reduced.
Die Konstruktion ist einfach und daher kostengunstig.The construction is simple and therefore inexpensive.
Die kompakte Ausführung eignet sich für die Umrüstung vorhandener Kesselan-lagen mit Rostanlagen.The compact version is suitable for retrofitting existing boiler systems with grate systems.
Die Erfindung ist anhand der Zeichnung und der zugehörigen Beschreibung nä-her erläutert.The invention is explained in more detail with reference to the drawing and the associated description.
Die Zeichnung zeigt eine schematische Darstellung der Feuerung eines Mü 11-kessels.The drawing shows a schematic representation of the furnace of a Mü 11 boiler.
Der, dem Müllaufgaberost 3 durch die Schurre 2 zugegebene Müll 1 wird von den, durch das Rauchgas-Gebläse 18 aus den Verbrennungsraum 6 gesaugten, heißen Rauchgasen durchströmt und getrocknet; dies findet vor der Verbren-nung auf dem Verbrennungsrost 4 statt. Hierdurch kann die Emission von Dioxinen, Furanen, CO und Cx Hy gering gehalten werden. Die Rückführung der Rauchgase durch das Rauchgas-Gebläse 18, die Rauchgas-Leitung 19 und die Rauchgas-Stichleitungen 20, 21, 22, 23 und deren Beimischungen mit der Frischluft in die Frischluft-Stichleitungen 11, 12 ,13, 14 ist durch entsprechende Einstellung der Regel- bzw. Absperrorganen 15, 24 des optimalen Rauchgas-/Luft-Verhältnisses in den einzelnen Unterwind-Zonen 4a, 4b, 4c, 4d des Verbrennungsrostes 4, für eine N0x-arme Verbrennung ohne weiteres möglich. Da die Trocknungsbrüden zwangsläufig durch die heißeste Verbrennungszone stromen, werden die enthaltenen Schwelgase und Schadstoffe (fluchtige Kohlenwasserstoffverbindungen usw.) verbrannt.The garbage 1 added to the garbage grate 3 through the chute 2 is flowed through and dried by the hot flue gases sucked out of the combustion chamber 6 by the flue gas blower 18; this takes place before the combustion on the combustion grate 4. As a result, the emission of dioxins, furans, CO and Cx Hy can be kept low. The return of the flue gases through the flue gas blower 18, the flue gas line 19 and the flue gas branch lines 20, 21, 22, 23 and their admixtures with the fresh air into the fresh air branch lines 11, 12, 13, 14 can be adjusted accordingly the control or shut-off devices 15, 24 of the optimal flue gas / air ratio in the individual underwind zones 4a, 4b, 4c, 4d of the combustion grate 4, for a low-NOx combustion possible without further ado. Since the drying vapors inevitably flow through the hottest combustion zone, the carbonization gases and pollutants contained (volatile hydrocarbon compounds, etc.) are burned.
