Wärtsilä 46GD multi-fuel power plant Key figures Plant output 10-400 MW Same fuel flexibility as Wärtsilä 32GD multi-fuel power plant Configuration 1-24 x 20V32GD A step further in terms of performance: a bigger unit Minimum load size allows the engine to be even more efficient Spinning mode 30% GD OPERATION: Original gas-diesel operation mode, Efficiency mode 3% where gas is the main source of energy, and pilot fuel oil injection is used to ignite the combustion. Available at any Efficiency 45% point between 30-100% of rated load, the plant can transfer to and from GD operation within this same range. >100%/min Ramp rate Regular start Sync Full FUEL SHARING: Available between 30-100% of rated time load. Simultaneous combustion of gaseous and liquid <1 min <6 min fuel, in a ratio that can be adjusted flexibly. The fuel share Sync Full Fast start set point can be adjusted online. The operator may also time change the set point at any time during operation. <1 min<3 min Ultra-fast start time FUEL OIL OPERATION: Regular Diesel-principle n/a Stop time combustion. Available for the whole load range and for any of the mentioned liquid fuels. < 1 min 34 35
