Abstract: PROBLEM TO BE SOLVED: To cause equalized volmetric heat quantity through both gas and liquid fuel. SOLUTION: One supply passage to a burner of a gas turbine is used for both liquid and gas fuel. The liquid fuel is treated by gas of a treatment device. A fuel pre-evaporator 1 is arranged for treating the liquid fuel. The fuel pre- evaporator 1 has an evaporation tube 2. The evaporation tube 2 is made of material having satisfactory heat conductivity. The evaporation tube 2 cooperates with a heating device 3. A supplying device 4 for cleaning gas is connected to one end of the evaporation tube 2, while a fuel supplying/ discharging device 5 is connected to the other.

Abstract: The supply process involves using the same supply path to the gas turbine for both liquid and gas fuels. The liquid fuel is prepared before it reaches the burner. This preparation takes place in a fuel pre-vaporiser which has a vaporising tube (2) to prepare the liquid fuel. The tube is made of a material with high thermal conductivity. It is connected at one end to a supply device (4) for a flushing gas and at the other end to a fuel supply and removal device (5). The vaporiser may create a thin film of fuel before vaporising it.
