720kw 900kVA Diesel Natural Gas Combined Engine Generator 60Hz with 30% Diesel 70% Gas

Standard Supply Scope:
Dual Fuel engine with alternator, 480V adjustable, 1200rpm/1800rpm, 60Hz
Air/Gas Mix System: Air/gas mixer, Controller, Pressure sensor
Governor System: Governor controller, Throttle, Sensor,
Gas Train:Ball Valve, Gas filter, Gas Regulator, Gas Control Valve
Gas Low Heat Value: ≥ 36MJ/Nm3
Maximum Gas Propotion: 70%

Applied gas:
Natural Gas,
Acceptable fuel gas pressure: 5~12kPa
CH4 content: for natural gas≥85% CH4 ,content:for biogas≥40%
Gas heat value≥5500kcal/Nm3 (23MJ/Nm3 ). Genset output power will increase as the gas heat value increase, if use low heat value gas for fuel (Heat value<5500kcal/Nm3, it will lower the power efficiency.
Gas doesn't include free water or free materials (the size of impurities should be less than 5μm.)
H2S content≤200mg/Nm³
NH3 content≤20mg/Nm³
Impurities content≤30mg/Nm³;size≤5μm
Water content≤40g/Nm³, no free water.

Acceptable working conditions:
Ambient temperature : -10°C~+40°C
(antifreeze or preheater needed for below 0°C)
Relative humidity:<90%(20°C)
Altitude:≤1000m
Normal working conditions:
Genset can run at rated power on the conditions:
Atmospheric Pressure: 100kPa, Ambient Temp: 20°C, Relative Humidity: 30%.

Quality Warranty Period:
All equipment is guaranteed for a period of 1000 hours running or 12 months from the date when the generator set has been delivered from the factory.

ATS System
For emergency power usage in building, Auto transfer switch (ATS) is essential. ATS can automatic transfer load from Mains power supplying to Emergency power. In normal, when the Main power supplying failure or voltage drop below 80% of normal voltage, ATS will auto start Emergency generator set after a preset time of 0-10 sec (adjustable according to the users). Once generator reach at rated speed, the ATS will transfer the load to emergency generator sets automatically.
