Patent ID: 7926288

Claim:
A reformed-fuel-burning gas turbine system comprising: a heavy oil heater for heating heavy oil under high pressure; a water heater for heating water under high pressure; a reformer vessel for mixing high-temperature, high-pressure water with high-temperature, high-pressure heavy oil to cause a hydrothermal reaction and producing reformed fuel from heavy oil; and a gas turbine which operates on the reformed fuel produced in said reformer vessel, wherein said system further comprises: a first detector for detecting the static dielectric constants or solubility of high-temperature, high-pressure heavy oil heated by said heavy oil heater and high-temperature, high-pressure water heated by said water heater; a first temperature regulating valve provided in a line for supplying a heating medium to said heavy oil heater and used to adjust the thermal dose of said heavy oil heater; a second temperature regulating valve provided in a line for supplying a heating medium to said water heater and used to adjust the thermal dose of said water heater; and a control device for adjusting said first temperature regulating valve and said second temperature regulating valve in accordance with the static dielectric constants or solubility of the heavy oil and water, which are detected by said first detector, in order to control the static dielectric constants or solubility of the high-temperature, high-pressure heavy oil and high-temperature, high-pressure water, which are to be supplied to said reformer vessel.
