The paper presents the results of experimental investigation of the effect of high injection pressure and water content on the ignition delay and lift-off length of combusting diesel-water emulsion (DWE) sprays in a constant volume chamber. DWEs with different water contents are injected at pressures up to 100 MPa into the combustion chamber under two different ambient conditions. The constant-volume chamber used allows optical access for visualization of the injection and combustion processes of the fuel. High-speed natural soot luminosity imaging is used to measure the ignition delay and lift-off length of the sprays. The experiments show that water content in the fuel and the initial temperature of the chamber have strong effects on the ignition delay and lift-off length of the emulsified sprays. Injection pressure, on the other hand, has little effect on the ignition delay but significant effect on the lift-off length.

“…The research confirmed the previously obtained results [37], which indicated that the optimal emulsion humidity is 10-15%. A further clarification of the recommended water content was obtained in the optimization process by maximizing the boiler's efficiency and minimizing the emission of nitrogen oxides and products of chemical unburning [39][40][41][42][43]. In this way, an optimal WME moisture content of 11-13% was achieved.…”

Disposal of Wastewater from Mazout-Fired Boiler Plants by Burning Water–Mazout Emulsions

Liquid fuel can be an alternative to solid fuel in non-gasified locations. The mazout for municipal-energy boiler plants is much cheaper than fuel oil. However, this relates to the problem of wastewater disposal from such a boiler plant. A proprietary system for the disposal of bottom water and other sewage-containing mazout has been developed. The solution depends on the proper preparation and burning of a water–mazout emulsion (WME). The emulsion is prepared in a specially designed and developed dosing ejector. By burning the emulsion using the developed system, an efficiency increase of 2–3% was achieved for boilers operating on the mazout fuel. Such a result was achieved due to a reduction in the excess air factor. Moreover, emissions of nitrogen oxides and carbon monoxide were reduced by 30–35% and 70–80%, respectively. In addition due to cleaning the heat-exchange surfaces obtained when working on the WME, the amount of time for productive and more efficient use of the equipment has increased.
