2MW heavy oil Diesel engine Generator
INTRODUCTION:
Dual fuel engine design is based on CSI HFO well run four stroke low speed engines; Provide same output whether running on Dual fuel or Diesel/HFO; Switchover from Dual Fuel mode to Diesel/HFO smoothly in engine operating; Low NOx Emission; High pressure gas injection for every cylinder; Precise gas injection timing, reliable and safety operation; 80% Diesel/HFO converted by NG, about 60% Fuel cost saving;

Benefit of Dual Fuel Operation Generator in HFO Mode:
LHV of HFO about: 10200 kcal/kg Fuel comsumption in full load: 215g/kwh, 1kg HFO=4.65kwh Turbochargered single gas generator operation(in market): Heating Value of the Natural gas about 9200kcal/Nm³ Gas comsumption in full load: 0.3Nm³/kWh, 1Nm³ gas=3.3kWh 1.0MW generator operating in dual fuel mode: Fuel/gas comsumption ratio: 70~80% gas, 20~30% diesel. HFO price in market: 0.74USD/kg HFO Power fee: 0.16 USD/kWh Natural gas price in market: 0.35USD/Nm³ Gas Power fee: 0.10 USD/kWh Dual-fuel operation: 0.16x25%+ 0.10 x75%= 0.11 USD/kWh Dual-fuel operation generating cost is half as the engine operating in HFO Generator can operate in single HFO mode, it give much reliable in power supply even if the shortage of the natural gas suppling.
Emission of Dual Fuel The emission of dual fuel engine is better than diesel engine: 1. NOx reduce 65% than diesel engine 2. CO reduce 54% than diesel engine 3. CO2 reduce 31% than diesel engine 4. CHx reduce 58% than diesel engine
