Definitions
- the present invention relates to a method according the preamble of claim 1 and to an installation according to the preamble of claim 8 as known from EP-A-0 875 671 or US-A-4 120 268 .
- large combustion engine means an engine of the kind exemplified by main or auxiliary engines of ships or power plants for the production of heat and/or electricity.
- the fuel used may be very easily ignitable gas or less easily ignitable heavy fuel oil.
- Fire fighting devices are as such very necessary security devices, but these kind of separate systems increase inter alia both investment costs and service costs.
- JP 9135917 addresses fire extinguishing in a combustion engine by describing a fire extinguishing arrangement for a vehicle engine. It suggests using cooling liquid from a closed cooling system circuit of the engine for extinguishing a possible fire. In this kind of arrangement there is, however, a very limited amount of cooling liquid for use as extinguishing liquid. Also, this requires a totally separate extinguishing system, which only uses the cooling liquid of the engine as a source of extinguishing liquid. Cooling liquid also typically contains substances which are not optimal for fire extinguishing purpose. Additionally, in this kind of method the possibility of keeping the engine running is lost, even if it otherwise would be possible. For example in marine applications this means loss of steerability of the vessel.
- the invention relates to fire fighting in connection with a combustion engine apparatus, which comprises at least one combustion engine unit and a source of fluid, comprising water, in co-operation with the combustion engine unit, a pressure booster device for said fluid and a nozzle arrangement for leading said fluid to the combustion engine unit.
- the fluid from the source is elevated from the pressure level of the source to higher pressure and is fed by means of said nozzle arrangement to a combustion chamber of the combustion engine unit and the fluid is rationed and timed in a manner which affects the operation of the engine in a desired way, and by virtue of a pre-determined event said fluid is led outside the combustion chamber of the combustion engine unit.
- the fluid comprising water
- the combustion chamber of the engine in the normal mode of operation it is possible to supply the fluid, comprising water, to the combustion chamber of the engine either directly or for example to inject it into the combustion air, along with which it is brought into the combustion chamber. It is important that the fluid can be rationed in the desired manner into the combustion engine.
- the fluid comprising water
- said fluid is led outside the combustion chamber of the combustion engine apparatus, and specifically in the case of a fire, the fluid fed in the normal mode of operation to the combustion chamber is led outside the combustion chamber of the combustion engine apparatus for extinguishing the fire.
- An installation for fire fighting according to the invention in connection with a combustion engine apparatus comprises at least a combustion engine unit and a source of fluid, comprising water, in co-operation with the combustion engine apparatus, a pressure booster device for said fluid and a nozzle arrangement for leading said fluid to the combustion engine unit and for affecting the operation of the engine in a desired way, as well as a flow channel arrangement, which combines said pressure booster device and the nozzle arrangement.
- the installation comprises a fluid joint arrangement provided in the flow channel arrangement and a fire fighting arrangement for enabling leading of the fluid by means of the fire fighting arrangement to a space outside the combustion chamber of the combustion engine unit.
- the combustion engine installation may further comprise a fire alarm arrangement or the like.
- the method for fire fighting in connection with a combustion engine apparatus may include a step of stopping the supply of said fluid into the combustion chamber of said combustion engine unit and immediately starting supply of said fluid outside the combustion engine unit by virtue of a signal given by the fire alarm arrangement or the like.
- the fire alarm arrangement or the like advantageously comprises at least a capability for manual launch, but desirably comprises both automatic and manual launch capabilities.
- said fluid normally fed into the combustion chamber will thus be led specifically for fire extinguishing purposes, and preferably introduced to locations which are selected taken into account the extinguishing of possible fires.
- this kind of location may comprise a space surrounding the combustion engine unit and possibly separate box structures in connection with engine.
- the fire fighting arrangement may comprise a fire fighting pipe system to which several extinguishing nozzles have been arranged. The nozzles are provided for spraying the fluid to the space surrounding the engine.
- the specific locations will be determined in more detail according to need.
- the combustion engine apparatus 1 in the figure comprises a combustion engine unit 2, which is preferably a large piston engine, and a source 3 of fluid, comprising water, in co-operation therewith.
- the source 3 may for example comprise a water supply system or separate water tank.
- the arrangement comprises a pressure booster device 4, such as a pump.
- the arrangement may be provided with fluid filtering devices according to need, which are not shown in the figure.
- the apparatus also comprises a nozzle arrangement 5 for leading said fluid to the combustion chamber 2' of the combustion engine unit 2.
- the fluid from the source 3 is elevated from the pressure level of the source to higher pressure and is fed by means of said nozzle arrangement to the combustion chamber of the combustion engine unit 2.
- the amount of fluid is rationed and the injection is timed in a manner which reduces the emissions from the engine.
- Combustion engine apparatus 1 further comprises a fire alarm arrangement 6 or the like, which emits a signal causing the supply of said fluid into the combustion chamber 2' of said combustion engine unit to be stopped, and causing the immediate commencement of supply of said fluid outside the combustion chamber 2' of the combustion engine unit, to a space 2" surrounding the combustion engine unit.
- the fluid may be led to suitable locations, such as outer surfaces of the engine, air space surrounding the engine and also inside any box structure in connection with the engine. The locations may be selected to be suitable for the respective case.
- the fire alarm arrangement 6 or the like is provided in co-operation with a fluid joint arrangement 8 arranged in a flow channel arrangement 5'.
- the fluid joint arrangement 8 preferably comprises a valve arrangement by means of which the flow of said fluid is selectably guideable either to the nozzle arrangement for guiding the fluid in to the combustion chamber 2' of the combustion engine, or to a fire fighting arrangement 9, which enables the leading of said fluid to the space 2"outside the combustion chamber 2' of the combustion engine apparatus.
- the fluid joint arrangement 8 may for example be a three-way valve or the like along with an actuator, known as such, whereas the fire alarm arrangement 6 or the like has been adapted to control said actuator.
- the signal from the fire alarm arrangement of the like may be automatically generated by the fire alarm arrangement of the like or it may be manually originated based on e.g. visual observation of smoke.
- the fire alarm arrangement or the like thus advantageously comprises separate, suitably located fire detectors, under control of which the alarm may be set.
- the combustion engine apparatus 1 further comprises an auxiliary operating arrangement 7 being substantially independent from the combustion engine apparatus 1 for maintaining the supply of said fluid, comprising water.
- This kind of auxiliary operating arrangement preferably comprises a backup electricity supply for the pressure booster device 4 from an emergency generator. This is turned on if the actual voltage of the normal mains supply (not shown in the figure) decreases below a pre-determined level.
- the flow channel arrangement 5' in the combustion engine apparatus connects said pressure booster device 4 and the nozzle arrangement 5.
- a separate fluid joint arrangement 8 has been arranged in the flow channel arrangement, which enables the leading of fluid to the space 2" outside the combustion chamber 2' of the combustion engine apparatus.
- the installation comprises a fire fighting arrangement 9 in connection with the fluid joint arrangement 8,which fire fighting arrangement 9 further comprises a fire fighting pipe system and several fire fighting nozzles 9' arranged for spraying said fluid, comprising water, into the space surrounding the engine.
- a fluid supply channel in connection with the combustion engine, from which channel the fluid may be conducted to the combustion chamber of each cylinder of a combustion engine, preferably a large combustion engine, through independently controlled injectors of an injector arrangement.
- the figure shows the injector arrangement extending directly to the combustion chamber.
- the introduction of fluid could take place in the parts of the engine by means of which substances participating in the combustion chamber are conducted to the combustion chamber.
- the fluid may be brought into the combustion air at a suitable stage.
- the figure shows a piston engine of an application, but it is clear that the invention may also be applied in connection with other types of combustion engines.
