Process for manufacturing emulsified fuels by using oily water

Abstract

The invention relates to a process for manufacturing emulsified fuels by using “oily water” that is proceeded by following steps: (1) preparing the “oily water” that has 0.02—30% (w/w) of combustible fuels dissolved in water and is blended with surfactants (or called as emulsifiers) by 0.01˜3% (w/w); (2) primarily mixing the emulsified “oily water with surfactants”, that was finished by step (1), with 60˜95% (w/w) of heavy fuel oil (abbreviation as heavy oil) or with 75˜98% (w/w) of diesel, respectively; and (3) keeping the mixtures that were finished by step (2), respectively, and mixed up further by using homogenizer to become an “oily water emulsified heavy oil” (OWEH) or an “oily water emulsified diesel” (OWED).

BACKGROUND OF THE INVENTION[0001]1. Field of the invention[0002]The invention relates to a process for manufacturing emulsified fuels by using “oily water”, that is proceeded by following steps: (1) preparing the “oily water” that has 0.02˜30% (w / w) of combustible fuels dissolved in water and is blended with surfactants (or called as emulsifiers) by 0.01˜3% (w / w); (2) primarily mixing the emulsified “oily water” with surfactants, that was finished by step (1), with 60˜95% (w / w) of heavy fuel oil (abbreviation as heavy oil) or with 75˜98% (w / w) of diesel, respectively; and (3) keeping the mixtures that were finished by step (2), respectively, and mixed up further by using homogenizer to become an “oily water emulsified heavy oil” (OWEH) or an “oily water emulsified diesel” (OWED). The OWEH and the OWED can be utilized for industrial boilers and diesel engines, respectively, not only elevates combustion efficiency and lower pollutant emission, but also save energy and reduce cost.[000...

Problems solved by technology

Therefore, in the combustion furnace, a high fuel concentration spot occurred and fuel was thermally decomposed in the oxygen lean condition to cause incomplete combustion and to produce a great amount of unburned carbon particulates and black smoke in the stack flue gases.

In this way, the incomplete combustion not only induced environmental pollutions, but also increased fuel consumption.

However, such a water-in-oil emulsified fuel not only can not achieve a stable emulsification condition, result in the separation of water and oil, but also do not display a significant energy saving fraction to afford a high expanse for the costs of emulsification process such as surfactants, hardware and labor costs.

Therefore, the emulsified fuels were
