The performance characteristics of aqueous emulsifier diesel oil of the present invention:
(1) the product technical recipe is reasonable, produces three-waste free pollution.
(2) properties of product are stable, and parts equipment is not increased corrosion and wearing and tearing.Be applicable to all kinds of domestic and imported diesel engines, rated power is constant, many test rates of economizing gasoline 7.9%, the practical rate of economizing gasoline 18.2% of railway locomotive.
(3) thermodynamic test: No. 0 the diesel oil thermal efficiency is 89.93%, and Fuel Consumption is 10.25kg/h.Use the diesel oil emulsifier of No. 70%0 diesel oil ten 30% water and 0.5%, the thermal efficiency is .91.5% under the kindred circumstances, and diesel oil emulsification consumption 10.93kg/h amounts to pure diesel oil 7.63kg/h.
(4) temperature contrast:
Pure No. 0 diesel oil caloric value: Q=44495.8Kg/h
Diesel oil emulsification: (No. 0 diesel oil 79%+20% water ten 1% emulsifying agents)
Caloric value: Q=4119 8.6kj//Kg
(5) performance analysis
Be used for various diesel engines, smoke intensity and noxious gas emission are than the pure diesel oil decline 25-75% of burning; Be used for all kinds of oil burning boilers, sulfur dioxide emissioning concentration descends 47%, and smoke dust discharge concentration descends 57%.
(6) application technology characteristics:
Aqueous emulsifier diesel oil of the present invention by the emulsification of ultrasonic emulsification machine, can be made into the agent of 1-5 μ water-in-oil type W-O emulsification of diesel oil with water.
The diesel oil emulsification proportioning that is used for internal combustion engine is:
