[investigation of result]
Can be while reducing CO although being shown by above-mentioned experiment2(fuel consumption), the situation of NOx, PM, but on the column
In, investigated with prospect from now on and problem for the reason.
It is considered as because in fuel oil mixing water so as to be imported into the air capacity of spraying that fuel consumption is enhanced in fig. 4
Increase, so the burning during particularly facilitating diffusion combustion.In addition, it is considered to be being increased by pre-mixing combustion amount improves combustion
Burn, PM is also reduced as shown in Figure 6.
In Figure 5, although NOx is reduced with the mixed proportion of water, but this is considered as the gasification of (1) along with the evaporation of water
The temperature reduction that heat is brought；(2) the increased influence of specific heat that the vapor that water evaporation is produced is brought.
In fig. 8, because the water particle of " small water particle type water mixed fuel " is several μm~about 20 μm of particle diameter, so passing through
The effect improved fuel consumption of microexplosion.
As shown in Fig. 9 and Figure 10, filled based on combustion jet because " oil or fat particles type water mixed fuel " need not be carried out
The micronized put, so (1) is not only disappeared by the atomization process in combustion chamber and improves burning can make fuel consumption
Be greatly reduced, (2) and also do not need fuel injection device in micronized mechanism, make to be equipped on the fuel of boiler, diesel engine
The low-cost and high-performance of injection apparatus is possibly realized.
If in addition, disappearing with fuel from the rate of load condensate in the case of using " the oil or fat particles type water mixed fuel " shown in Figure 10
From the point of view of the relation of consumption, under full load rate, fuel consumption is enhanced 7~8%.Accordingly understand, no matter fuel injection amount, injection pressure
How is the external factor of power, the temperature of combustion chamber etc., and burning is all enhanced.
The illustraton of model of spray burning when Figure 11 represents that water mixed fuel is used.Figure 11 (a) is the situation of only fuel oil, Qa
The spirogram of the fuel oil that will be injected is shown as bar-shaped.Figure 11 (b) is the situation that water is mixed with fuel oil, by mixed in fuel oil
Heshui, so as to by the amount Qb of the fuel to being injected added with mixed water amount Qc so that total emitted dose (Qb+Qc) increases
Plus, and it is imported into the air capacity increase of spraying.That is, the combustion that is injected roughly equal relative to Qa is compared with Figure 11 (a)
The air capacity of the amount Qb of material increases, therefore burning during diffusion combustion is especially promoted, and there is PM along with fuel consumption quilt
The possibility for improving and reducing.In addition, the increase of the specific heat after heat of gasification when water evaporation and evaporation, ignition temperature drop
Low, NOx is reduced.In Fig. 4~Fig. 6, fuel consumption is enhanced if the mixed proportion increase of water, and NOx and PM reduces quilt
It is considered the reasons why being based on such.
Figure 12 represents the ideograph of the spray burning process of fuel oil.As shown in figure 12, from the thinner of Fuelinjection nozzle
The spout of nozzle micronized and is evaporated with the fuel oil F that high speed sprays in combustion chamber.In the atomization process and thereafter
Evaporation process in be mixed into flammable gaseous mixture from the air for around importing, oneself caught fire out afterwards in about 1ms (millisecond)
Begin to burn.So, in existing spray burning device, the fuel from combustion ejection device injection is via " micronized ", " steaming
The two processes move to combustion process to hair ".
Figure 13 represents " the tiny oil droplets type water mixed fuel " generated by the water mixed fuel generating means A of present embodiment
Spray burning process ideograph.As shown in figure 13, be substituted by by by the fuel oil shown in Figure 12 " oil or fat particles type water mix
Close fuel ", so as to start " evaporation process " in combustion chamber without through " atomization process " as shown in Figure 12, therefore fuel
Consumption is further enhanced.But, burning is activated so as to the generation of NOx is promoted, therefore NOx has as increase trend
Possibility.Under the identical operating condition shown in Fig. 5, value ratio " the small water droplet of the NOx of " tiny oil droplets type water mixed fuel "
It is considered as because the reason that the value of the NOx of type water mixed fuel " is high.
According to the above results, filled by the fuel injection in the machine K of fuel oil drum T1 and engine or boiler etc.
The water mixed fuel generating means A of present embodiment is set between putting, while (1) can realize fuel consumption, NOx and PM
Reduce, and (2) are by being arranged at the machine K and fuel of a mode that is, engine or boiler etc. of fuel injection device
Between oil tank T1, " tiny oil droplets type water mixed fuel " is supplied to combustion chamber such that it is able to will directly be sprayed by the oil droplet of micronized
Penetrate in combustion chamber (the micronized mechanism in can making fuel injection device disappears), therefore can not only be by fuel injection device letter
Dan Hua, and spray burning (promoting burning) can be improved.
In addition, the combination by reducing technology with other NOx such as SCR, EGR, it is also possible to expect as IMO (International Maritimes
Mechanism：International Maritime Organization) 3 times limitation correspondence technology effects.
