Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy oil is modified by reaction with high-temperature and high-pressure water to remove heavy metals, then the fuel becomes suitable for gas turbine combustion, but the system complexity increases due to the need for integrated modification and power generation lines
Solution Approach 1:
The patent combines the heavy oil modifying line and gas turbine power generation line into an integrated system where the reactor, gas-liquid separator, and combustor operate as a unified process. This merging allows the system to handle heavy oil conversion and power generation simultaneously, reducing overall system complexity despite the sophisticated processes involved.
Solution Approach 2:
The hydrocarbon gas produced from heavy oil modification serves dual purposes: it can be used as fuel for the gas turbine combustor or extracted externally for other uses. This multi-functionality allows the system to adapt to different operational requirements while maintaining a relatively simple integrated structure.
2Adaptability or versatility
If hydrocarbon gas is extracted externally before supplying to combustor, then operational flexibility and safety are improved, but the device complexity increases due to additional extraction lines
Solution Approach 1:
The system incorporates dynamic control capabilities that allow operators to adjust the degree of external extraction of hydrocarbon gas based on operational needs. The extraction line can be configured to provide varying amounts of gas to external uses while maintaining sufficient supply to the combustor, enabling flexible adaptation to different power generation and fuel requirements.
3Reliability
If modified oil is stored in a tank during reactor startup, then continuous fuel supply to gas turbine is ensured, but the system complexity increases due to additional storage infrastructure
Solution Approach 1:
The modified oil tank serves as a preliminary storage facility that accumulates fuel during reactor startup and before hydrocarbon gas production begins. This preliminary action ensures that the gas turbine combustor has continuous fuel supply available, preventing operational interruptions during the transition period when the reactor is being brought online.
4Reliability
If heavy oil modification and gas turbine operation are controlled in link, then safety during startup and shutdown is improved, but the control complexity increases
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the operational state of both the heavy oil modification process and the gas turbine. By continuously monitoring parameters such as reactor temperature, pressure, and fuel flow rates, the system can automatically adjust operations to maintain safe conditions during startup, normal operation, and shutdown sequences, reducing the need for complex manual control procedures.

AI summary
A gas turbine system burning heavy-oil modified fuel and a method of operating the gas turbine system, which covers from a stage of modifying heavy oil and producing gas turbine fuel to a stage of operating a gas turbine, including startup, ordinary shutdown and emergency shutdown of the gas turbine. The gas turbine system burning heavy-oil modified fuel comprises a reactor for mixing heavy oil and water to cause reaction, thereby separating and removing a heavy component from the heavy oil, a gas-liquid separator for separating hydrocarbon gas and modified oil obtained in the reactor from each other, a gas turbine combustor for burning the hydrocarbon gas supplied from the gas-liquid separator, and a gas turbine driven by combustion gas produced in the gas turbine combustor. The system further comprises another line for extracting the hydrocarbon gas externally of a relevant system region. The other line is branched from a line for supplying the hydrocarbon gas from the gas-liquid separator to the gas turbine combustor.
