Abstract

A stationary IC engine (1) such as a diesel engine or a gas engine has its exhaust gases directed into the combustion chamber of a coal-fired boiler (7) which is pref. of the travelling grate type. The diesel or gas engine (1) is used for driving an electricity generator (2) while the coal fired boiler (7) generates steam which drives a steam turbine (8) which drives a second electricity generator (9). The exhaust gases from the IC engine are mixed either with the primary combustion air or with the secondary combustion air or with both primary and secondary combustion air supplied to the boiler. USE/ADVANTAGE - Electricity generation by a method which increases the thermal efficiency of the plant and reduces the emission of harmful gases such as nitrous oxides.

Description

Die Erfindung betrifft einen stationierten gas- oder dieselgefeuerten Verbrennungsmotor. Derartige Motoren dienen u. a. dem Antrieb von Stromaggregaten. Allerdings ist der Betrieb stationärer Verbrennungs­ motoren in besonderer Weise emissionsbelastet. Die Verbrennungsgase entwickeln sich nur an einer Stelle. Deshalb ist die Umwelt in beson­ derer Weise belastet.The invention relates to a stationary gas or diesel-fired Internal combustion engine. Such engines serve u. a. the drive of Generators. However, the operation is stationary combustion engines are particularly polluted with emissions. The combustion gases only develop in one place. That is why the environment is special burdened.

Der Erfindung liegt daher die Aufgabe zugrunde, die Stickoxydbelastung beim Betrieb stationärer Verbrennungsmotoren zu verringern. Nach der Erfindung wird das dadurch erreicht, daß die Abgase des Verbrennungs­ motors einer Rostfeuerung zugeführt werden. Besonders geeignet ist eine Wanderrostfeuerung.The invention is therefore based on the problem of nitrogen oxide pollution to reduce when operating stationary internal combustion engines. After Invention this is achieved in that the exhaust gases from the combustion motors are fed to a grate furnace. Is particularly suitable a moving grate firing.

Die Abgase des Verbrennungsmotors können zusammen mit der Primär- oder Sekundärluft zugeführt werden. Es zeigt sich, daß neben der Umweltent­ lastung aus dieser Maßnahme auch eine Energieeinsparung sowie eine Verbesserung der Stromkennziffer in Bezug auf den kombinierten Prozeß erwächst, wenn die Rostfeuerung gleichfalls der Stromerzeugung dient. Weitere Vorteile sind Einsparungen bei Investitionen und Betriebs­ kosten, da beispielsweise der sonst notwendige Katalysator zur NOx- Minderung der Abgase entfallen kann.The exhaust gases from the internal combustion engine can be supplied together with the primary or secondary air. It shows that in addition to the environmental relief from this measure, there is also energy saving and an improvement in the electricity indicator in relation to the combined process if the grate furnace also serves to generate electricity. Further advantages are savings in investment and operating costs, since, for example, the otherwise necessary catalyst for NO x reduction of the exhaust gases can be omitted.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

Mit 1 ist ein stationierter Dieselmotor bezeichnet. Der Dieselmotor 1 betreibt einen Stromgenerator 2. Seine Abgase verteilen sich auf Lei­ tungen 3 und 4, die in die Ansaugleistungen von Gebläsen 5 und 6 mün­ den. Das Gebläse 5 ist ein Primärluftgebläse, das Gebläse 6 ein Se­ kundärluftgebläse. Beide Gebläse wirken auf eine Wanderrostfeuerung 7. 1 with a stationary diesel engine is designated. The diesel engine 1 operates a power generator 2 . Its exhaust gases are distributed on lines 3 and 4 , which flow into the intake capacities of fans 5 and 6 . The blower 5 is a primary air blower, the blower 6 is a secondary air blower. Both fans act on traveling grate firing 7 .

Mit der Wanderrostfeuerung 7 wird Dampf erzeugt, der über eine Dampf­ turbine 8 einen Stromgenerator 9 treibt. With the traveling grate firing 7 steam is generated, which drives a power generator 9 via a steam turbine 8 .

Die Abgase aus der Wanderrostfeuerung gelangen über einen Gewebefilter 10, ein Abgasgebläse 11 und einen Kamin 12 ins Freie.The exhaust gases from the traveling grate firing are released into the open via a fabric filter 10 , an exhaust gas blower 11 and a chimney 12 .
