The Dual Fuel System described offers several significant advantages and operational details:
Advantages:
- Fuel Cost Savings: By blending diesel fuel with natural gas (biogas, CNG, LNG), the system can reduce overall fuel costs, as natural gas is often less expensive than diesel fuel.
- Fuel Flexibility: The ability to use both diesel and natural gas provides flexibility in fuel choice based on availability, cost, or specific operational requirements.
- Run-time Extension: During natural disasters or other emergencies, the dual fuel capability ensures extended run-time by utilizing available fuel sources effectively.
- Emissions Reductions: Natural gas generally produces lower emissions compared to diesel fuel, contributing to environmental benefits such as reduced particulate matter and nitrogen oxides.
- Utilization of Ancillary Gas Sources: The system can utilize various alternative gas sources such as field gas, flare gas, or landfill gas, expanding fuel sourcing options and reducing waste.
System Operation:
- Combustion Chamber Design: The Dual Fuel System blends natural gas with engine intake air, delivering this mixture to the combustion chamber through the air-intake valve.
- Ignition Mechanism: A small quantity of diesel fuel is injected into the combustion chamber as a pilot ignition source. This diesel pilot ignites the air-gas mixture, facilitating combustion.
- No Engine Modifications: The system integrates seamlessly with existing engine components without requiring modifications to critical parameters such as injection timing, valve timing, or compression ratio.
- Performance Consistency: After installation, the generator maintains its rated performance capacity in both 100% diesel and dual fuel modes. There is no compromise in generator load response or stability, ensuring reliable operation under varying fuel conditions.
Performance:
- Stable Power Output: Whether operating on diesel fuel alone or in dual fuel mode, the generator retains its rated load response and stability. This consistency is crucial for applications requiring reliable and uninterrupted power supply.
Overall, the Dual Fuel System offers a robust solution for generators, combining operational flexibility with economic and environmental benefits. It optimizes fuel usage, enhances reliability during emergencies, and supports sustainability efforts through reduced emissions and utilization of diverse fuel sources.es the performance of the generator relative to the rated load of the machine. A generator with a 1000 kW stand-by rating which has been retrofitted to Dual Fuel will still provide the same power in both 100% diesel and Dual Fuel modes. Similarly, there is no decrease in generator load response or stability while operating in either fuel mode.
