Abstract
Description
Die Erfindung betrifft eine Kesselfeuerung zur Verbrennung von Müll, insbe sondere feuchtem Müll, die mit einem Verbrennungsrost und einem vorgeschal 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 for the combustion of waste, in particular special damp garbage, with a combustion grate and a pre-form Teten rubbish feed grate is provided, the underwind zones of burning grate with preheated air and that of the waste feed grate with rezir are loaded with the flue gas.
Aus der Literatur ist bekannt, daß die Dioxin- und Furanemissionen bei feuchtem Müll wesentlich höher als bei trockenem Müll sind.It is known from the literature that the dioxin and furan emissions at wet garbage are much higher than dry garbage.
Durch die DE 39 13 885 A1 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.DE 39 13 885 A1 is a boiler firing for firing damp Fuels become known, which are equipped with a grate and a orderly device for predrying the fuels is provided. At this well-known furnace was the furnace grate for fuel feed extends and serves as a drying grate for the damp in front of the firebox Fuel. For the drying the underwind zones of the drying rust, adjustable with flue gas or preheated air.
Durch die DE 39 13 886 A1 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 Unterwind zonen dosiert zugeführt werden.DE 39 13 886 A1 describes a method for reducing emissions and to optimize fire control during grate firing through recirculation lation of flue gases has become known, in which the flue gases the front Underwind zones and / or the main air zones and / or the rear underwind zones are metered supplied.
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 expensive The 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, kosten günstige Konstruktion aufweist und die Anforderung für eine schadstoffarme Verbrennung des feuchten Mülls erfüllt. The object of the invention is a boiler firing for the combustion of To create garbage, especially wet garbage, that is easy, cost has favorable construction and the requirement for a low-pollutant Burning the wet garbage met.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Eine alternative Ausgestaltung der Erfindung ist in dem Unteranspruch angegeben.This object is achieved by the characterizing features of Claim 1 solved. An alternative embodiment of the invention is specified in the subclaim.
Durch die erfindungsgemäßen Maßnahmen werden die folgenden Vorteile er zielt:The measures according to the invention provide the following advantages aims:
Der Ausstoß, besonders von Dioxinen, Furanen, CO, NOx und Cx Hy, wird ver mindert.The emissions, especially of dioxins, furans, CO, NO x and C x H y , are reduced.
Die Konstruktion ist einfach und daher kostengünstig.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 boilers were with rust systems.
Die Erfindung ist anhand der Zeichnung und der zugehörigen Beschreibung nä her erläutert.The invention is based on the drawing and the associated description ago explained.
Die Zeichnung zeigt eine schematische Darstellung der Feuerung eines Müll kessels.The drawing shows a schematic representation of the furnace of a garbage 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 NOx-arme Verbrennung ohne weiteres möglich. Da die Trocknungsbrüden zwangsläufig durch die heißeste Verbrennungszone strömen, werden die enthaltenen Schwelgase und Schadstoffe (flüchtige Kohlenwasserstoffverbindungen usw.) verbrannt.The garbage 1 added to the garbage feed 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 C x H y 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 4 a, 4 b, 4 c, 4 d of the combustion grate 4 , for a low-NO x combustion possible without further notice. Since the drying vapors inevitably flow through the hottest combustion zone, the carbonization gases and pollutants contained (volatile hydrocarbon compounds, etc.) are burned.
