Abstract

The eddy layer heating arrangement (1) has an expanding eddy bed (2) together with an expeller/eddy producer (3) and a wall spoiler (4). Within the expeller/eddy producer, sec. air and flue gas are mixed together which leads to a redn. in the emission of harmful gas-form substances, e.g. CO, NOx and SO2. The combinaiton of a wall spoiler with the expeller/eddy producer contributes further to the emission of harmful substances. USE/ADVANTAGE - To reduce the atmospheric content of CO, NOx and SO2.

Description

Wirbelschichtfeuerungseinrichtungen sind ausge­ rüstet mit einem über der Schicht befindlichen Freiraum und einer Sekundärlufteindüsung in diesem.Fluid bed furnaces are out equips with one above the shift Free space and a secondary air injection in this.

Hierdurch wird die CO- und/oder die NOx-Emission vermindert bzw. der Ausbrand verbessert.As a result, the CO and / or NO x emissions are reduced or the burnout is improved.

Um die Effektivität dieser Maßnahme im Freiraumbe­ reich zu verbessern, wird erfindungsgemäß vorge­ schlagen, einen Verwirbler bzw. Verdrängerkörper in spezieller Ausführung einzubauen.To the effectiveness of this measure in open space To improve richly, according to the invention hit a swirler or displacer in special version.

Hierdurch wird eine intensive Verwirbelung ermög­ licht, und die Emission o. g. Schadstoffe kann we­ sentlich vermindert werden.This enables intensive swirling light, and the emission o. g. We can pollutants be significantly reduced.

In der beiliegenden Zeichnung ist ein prismaartiger Körper dargestellt, der zu einer wesentlichen Ver­ besserung der Verwirbelung dient und erfindungsge­ mäß vorzugsweise oberhalb des expandierten Wirbel­ bettes installiert wird. In the accompanying drawing is a prismatic one Body shown that leads to an essential ver improves the turbulence and fiction preferably above the expanded vertebra bed is installed.  

In der Zeichnung ist dargestellt: mit (1) die Umrisse einer Wirbelschichtfeuerung im Halbschnitt, mit (2) das expandierende Wirbelbett, mit (3) der Verdränger/Verwirbler, mit (4) die in Anspruch 2 erwähnten Wandspoiler.The drawing shows: with ( 1 ) the outline of a fluidized bed combustion in half section, with ( 2 ) the expanding fluidized bed, with ( 3 ) the displacer / swirler, with ( 4 ) the wall spoiler mentioned in claim 2.

Es ist weiterhin vorteilhaft, wie auch bereits in einer früheren Anmeldung des Ammelders (P 37 44 268.6) genannt, daß zusätzlich sogenannte Wandabweisvorrichtungen in Form von Wandspoilern installiert werden, die durch ihre Formgebung eine weitere Reduzierung der CO- bzw. NOx-Emission bewirken.It is also advantageous, as already mentioned in an earlier application by the registrar (P 37 44 268.6), that so-called wall deflection devices in the form of wall spoilers are also installed, which, through their shape, bring about a further reduction in CO or NO x emissions .

Claims (2)

1. Feuerung, vorzugsweise mit einem oberhalb des ex­ pandierten Bettes angeordneten Verdrängerkörper oder Verwirbler, dadurch gekennzeichnet, daß der Verdränger/Verwirbler Sekundärluft und Rauchgas innig miteinander vermischt und somit zu einer Reduktion der Emission gasförmiger Schadstoffe, vorzugsweise CO, NOx und SO2, führt.1. Furnace, preferably with a displacement body or swirler arranged above the expanded bed, characterized in that the displacer / swirler mixes secondary air and flue gas intimately and thus to reduce the emission of gaseous pollutants, preferably CO, NO x and SO 2 , leads. 2. Vorrichtung und Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß der dargestellte Verdränger/ Verwirbler in Verbindung mit kombinierten Wandspoi­ lern Anwendung findet und dem gleichen Zweck wie in Anspruch 1 dient bzw. die dort genannten Emissionen weiter vermindert.2. Device and method according to claim 1, characterized characterized that the displacer / Swirlers in combination with combined wall spoils learn application and the same purpose as in Claim 1 serves or the emissions mentioned there further decreased.
