Technical Specification

What is dual-fuel
1. principle and technology process:

Dual-fuel genset means its engine can combust two types of fuel—diesel and gas. Gas is the main fuel and diesel is used for ignition for the mixed gas of air and gas inside of engine. A part of diesel is injected into the cylinder for ignition when compression stroke nearly finish, so the genset still keeps diesel engine operation mode.

2. Advantages of dual-fuel system
Traditional diesel engine is rebuilt into dual-fuel system which adopts natural gas as main fuel so as to lower operation cost for power generation. The system adopts technologies for taking advantage of natural gas, and controls its flow rate upon the engine speed and output.

3. Dual fuel benefits: 
-Burn cheaper natural gas in diesel engine
-Flexible and automatic adaptability as load demand
 -Easy transfer between pure diesel and dual-fuel mode.
-Reliable and stable power output
 -High efficiency, safe and low emission
 -Longer overhaul term, longer engine lifetime and lower maintenance cost

APPLICABLE FUEL
Light diesel, heavy fuel oil, natural gas.
Natural gas: CH4 content ≥70%;

Usual requirements of gas within one meter from engine:
gas pressure~10kPa(change≤1kPa/min), gas temperature 5~45℃, particulate size≤5μm, particulate content≤30mg/Nm3, water content≤40g/Nm3,total tar/dust content≤100mg/Nm3.
Gas flow rate meets the requirement of maximum power capacity of genset.

RUNNING CONDITIONS
At ISO conditions(atmosphere pressure 100kPa, ambient temperature 25℃,RH 30%),the genset can output rated power within 24 hours, 90% load level is advised, 10% overload allowed within 1 hour.
Acceptable running condition ranges of the genset: ambient temperature -20℃~+40℃, RH<90%(20℃), altitude≤2000m.
