    when turbine trips

    There is supposed to be, often or always is a vent valve between the Speed ratio valve and the gas control valve. Look in the device summary for solenoid 20VG. When the gas system is not used this vents the inter valve area and keeps the turbine safe, keeps gas from entering the unit. If you...

    Heavy Fuel oil turbines?

    The metals in heavy fuels cause corrosion in the hot section of the gas turbine. Vanadium and other heavy metals are liquid at the operating temperatures.

    Success Stories on Starting up your Business

    What do you charge for engineering services??? What are your competitors charging? Who are your competitors? I am competing with employees, a company can hire employees instead of my business. This limits what I can charge. If I am competing against other consultants then my rate goes up.
