Correct component selection can overcome problems in the functioning of liquid fuel systems in
dual-fuel gas turbines. Using the appropriate liquid fuel, purge air and water injection check valves will provide more than 95% availability and reliability — which is far better than the typical 35% – 40% in most dual-fuel applications.
Ensuring fail safe
Over the past 30 years, utilities have paid millions of dollars in additional cost when purchasing turbines that have dual-fuel capability or the ability to operate on both natural gas and liquid fuel. While a wide variety of devices have been tried over the years, until fairly recently, technology that addresses all of the primary causes of fuel system failures did not exist.
