What the heck is emulsified diesel?

Emulsified diesel (microemulsified diesel) is a water-in-oil (W/O) type (transparent) emulsion formed by emulsifying diesel with water (or methanol) using emulsifiers and co-emulsifiers in specific emulsification equipment.

It’s an energy-saving economy; it’s not due to poor quality of the oil, but rather it’s a product.

Features: Simple to operate (only mechanical stirring is required)； Abundant raw materials available (emulsifiers such as by-products from vegetable oil factories or refineries), low energy consumption (the heat released by oil combustion is less relative to the amount of water used, meaning the combustion efficiency is higher) ； Low pollution (the particulate matter (PM10) and nitrogen oxides (NOx) emitted during combustion are significantly reduced after emulsification) ； Advantages such as improved fuel efficiency (as a result of secondary atomization, etc.) ； Tax incentives (products related to energy conservation and emission reduction are eligible for tax reductions; **the relevant departments provide strong support**).

Property: Microemulsified diesel is visually transparent, while emulsified oil is opaque； The particle size of microemulsions is less than 100 nanometers, while the particle size of emulsified oil is approximately 0.1 to 10 micrometers ； The amount of emulsifier used in microemulsions is much greater than that required for emulsification ； The stability of microemulsified oil is better than that of emulsified oil.

When the temperature rises sharply, the water with a lower boiling point boils and vaporizes first. When the expansion pressure of the water exceeds the sum of the oil’s surface tension and the ambient pressure, the water vapor breaks through the barrier of the oil film, resulting in secondary atomization that divides the oil droplets into tiny particles. The total specific surface area of the tiny oil particles in contact with air **increases**. At the same time, the micro-explosions generate numerous shock waves that break through the CO2 and N2 suppression layers surrounding the flame surface, thereby creating intense turbulence in the air. This leads to a more even distribution of air and fuel oil within the combustion chamber, as well as a more uniform temperature field. As a result, the combustion rate increases, backburning is reduced, local overheating in the combustion area is avoided, thermal decomposition of the oil is diminished, and the oil burns more completely, achieving the effect of energy savings and emission reduction. Accelerates the combustion reaction: Water vaporizes into water vapor during combustion, generating numerous OH active groups that facilitate the complete combustion of carbon monoxide. The water-gas reaction accelerates the combustion of the coke formed by fuel pyrolysis, thereby suppressing the formation of smoke and dust. Reducing NOx formation: The vaporization of water droplets requires heat absorption, which helps to prevent localized high temperatures in the combustion flame. Moreover, burning oil mixed with water improves the mixing ratio between fuel and air, reducing the excess air coefficient and thereby suppressing the formation of NOx and minimizing environmental pollution.
