Method for manufacturing gasified fuel and method and apparatus for heat recovery in manufacturing gasified fuel

摘要

A liquid fuel which contains water, such as Orimulsion or other water emulsion, is converted to a gasified fuel by heating the liquid fuel to a temperature which enables separation into a water layer and a fuel layer, separating the fuel layer, and gasifying the fuel of the fuel layer just after separation, by partial oxidation. Separation can be facilitated by also adding an emulsion breaker and/or applying an electric field. Gasified fuel 16 containing water vapor and sulfur compounds is cooled 3, 5, 6 to a temperature below the temperature at which water vapor condenses, said cooling including contact with a saturating heat exchanger 5, then converted 7 to a desulfurized gasified fuel by being brought into contact with an adsorbent, the desulfurized gasified fuel 21 thereafter being heated by contact with said saturating heat exchanger while having water 24 added thereto, before use, eg, in a gas turbine 8.
