(54) METHOD OF OPERATING A FUEL FIRED COMBUSTION APPARATUS IN
CONJUNCTION WITH A DIESEL ENGINE
(71) We, OY WARTSILA AB, a Fmn- ish Company of P.O. Box 230, 00100 Helsinki 10, Finland, do hereby declare the invention, for which we pray that a Patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following
Statement:
This invention relates to a method and an arrangement for producing heat energy and mechanical energy in a power plant.
Afterburners are known in which fuel is added to, and combusted in the exhaust of, e.g., a jet or gas turbine. However the efficiency ratio of these turbines is relatively low compared, for example, with the efficiency ratio of a diesel engine.
The aim of the present invention is to improve the total efficiency of a power plant, based on a diesel engine unit, by mak mg use of the exhaust gases of the diesel engine for the production of heat energy.
According to one aspect of the present invention, a method for producing mechanical energy and heat energy in a power plant, comprises operating a diesel engine to produce the mechanical energy, reacting, in a separate burner, high temperature oxygen present in exhaust gases of the diesel engine with additional fuel, supplied to the burner, to produce said heat energy, and making use of the produced heat energy in a heat exchange process separate from the process of producing the said mechanical energy.
The advantage of this method compared with known methods using a conventional burner-boiler combination is that the oxygen burned in the burner (or afterburner) is already hot and therefore does not have to be heated as is the case for the oxygen or reaction air in a conventional combustion process.
The amount of energy produced by the heat exchange process can be controlled as required by varying the amount of exhaust gases and/or fueld supplied to the burner.
The amount of fuel supplied to the burner can be controlled, for example, by varying the feed pressure of the fuel and/or by varying the number of fuel providing nozzles.
In the afterburner, heavy fuel oil, natural gas or the like can be used as fuel.
According to another aspect of the present invention an arrangement for producing mechanical and heat energy in a power plant, comprises a diesel engine for producing the mechanical energy, a device connected to, and adapted to use, the mechanical energy of the diesel engine to said burner, fuel supplying means for supplying fuel to said burner for reacting with high temperature oxygen present in the exhaust gases of the diesel engine supplied to the burner to produce heat energy, and a heat exchanger, for example, an exhaust gas boiler, separate from the diesel engine for using the heat energy produced in said burner. The outlet system for the exhaust gases may be provided with a device, by means of which the amount of exhaust gases supplied to the burner can be controlled. A device suitable for this purpose is a three-way valve, which, when required, passes the excess amount of exhaust gases through a silencer to the open air.
The feed pressure of the fuel can be controlled by means of the fuel feeding device of the burner. By providing the burner with several fuel feeding nozzles the amount of fuel fed can be controlled, for example, by varying the number of nozzles in use of by using adjustable nozzles.
If the diesel engine does not produce sufficient exhaust gases to the burner, for example, when the engine is at standstill or idling or for any other possible reason, it is of advantage to provide a possibility of blowing atmospheric air to the burner, so that the heat energy is produced either partly or entirely independently of the operation of the diesel engine. In this way a supply of heat power from the arrangement is guaranteed when the diesl engine does not provide the burner with sufficient amounts of exhaust gases for producing the required amount of energy.
The invention will now be described, by way of example, with reference to the accompanying drawing, the single Figure of which schematically shows an arrangement intended for applying the method according to the invention.
In the drawing, the numeral 1 designates a diesel engine connected to a device 2 using the mechanical energy of the diesel engine, which device may be, for example, a generator. The exhaust gases of the engine 1 are led through a three-way valve 3 either to an afterburner 4 and from there into an exhaust gas chamber 5 functioning as a heat exchanger, or through a silencer 6 to the open air. The numeral 7 indicates a device, which, when required, blows atmospheric air to the burner.
The invention is not limited to the embodiment shown, but several modifications are feasible within the scope of the attached
