2. Description of the Related Art In recent years, gas turbines are rapidly spreading as industrial gas turbine cogeneration systems because of their high efficiency, clean exhaust gas and easy maintenance. Conventionally, in this gas turbine, it is known that sulfur and metal (ash) in the fuel oil used cause corrosion of the turbine blades. It is anticipated that it is advantageous to have a low yield and a low particulate matter content in the fuel oil. In recent years, from the viewpoint of energy saving, high calorie fuel oil tends to be required. Conventionally, kerosene and fuel oil A are mainly used as fuel for turbines. Here, kerosene is a fuel that has extremely low sulfur content, metal content (ash content), generation of soot and fine particles, and has little corrosion of gas turbine blades, but has a drawback of low calorific value. On the other hand, fuel oil A is generally superior in terms of stable supply and has a higher calorific value than kerosene, but has the disadvantage that coking is likely to occur due to residual heat when gas turbine operation is stopped. ing. Fuel oil C is known as a fuel oil having a higher calorie than the fuel oil A. However, since fuel oil C has a high viscosity, it is inconvenient to handle, for example, requires heating equipment. Ash, sulfur, soot generation, residual carbon content, fine particles, etc., and the gas turbine blades are highly corroded. Therefore, they are difficult to use as fuel oil for gas turbines.
