Advantage for dual fuel generator sets
1.Can save big amount fuel consumption , to reduce the running cost . When the dual fuel generator sets working at dual fuel condition , rated output is equal to pure diesel fuel working state . When working under high load situation , natural gas substitution rate can achieve 70%
2.The dual fuel generator set can transfer to pure diesel fuel operation mode when there is no natural gas .
3.By reducing emissions, changing the atmosphere quality, maintaining the natural ecological environment, can improve people's lives . We can change operation mode between diesel fuel and dual fuel by fuel selector switch . It is easy to switch diesel fuel mode to dual fuel mode , also from dual fuel mode to diesel fuel mode . When the dual fuel generator set working under diesel fuel mode , the controller will close the natural gas function , only switch to diesel fuel working condition . At that time , its operational principle is same as diesel generator set . When the dual fuel generator set working under dual fuel mode , diesel fuel will be controlled at limited capacity ( normally at 20% to 30% of full loading ) , rest power will be achieved by natural gas .
Safety and reliability
1.Digital controller : reliable and precise control , keep the system always under optimal state .
2.When the engine under pure diesel fuel working condition , solenoid valve will cut the natural gas supply automatically .
3.Under same loading , the cooling temperature for dual fuel mode is lower 20 to 30 Celsius degree than under pure diesel working condition .
Diesel fuel / natural gas dual fuel controller system , achieve following characteristics :
1.Diesel substitution rate : 60% to 75%
2.Power keep the same as diesel generator set
3.Operation is easy , same as diesel generator set
4.Simple modification, low cost, the investment recovery period is short
Conclusion
Compare with diesel generator set , dual fuel generator set's emissions standard is significantly optimized . Reduce the harmful substance , such as nitrogen oxide , hydrocarbon so on . Smoke exhaust system is greatly improved , has the good social efficiency . Dual fuel generator set as the green power , not only replace diesel generator set to meet the rig, mobile power station, industrial production, residential quarters and other market on the generator needs , but also meet the national requirements of sustainable development .
Warning
1.In strict accordance with the instructions for use the installation of gas pipeline and gas control device, to prevent gas leakage
2.Using independent speed sensor to the device with rotating speed signal
3.Use a external gas control switch and a controller relay for control the gas supply and cut off .

Based on the diesel generator set reliability , duel fuel generator set also have gas genset's advantages , such as economic and environmental protection . Our company absorb advanced technology , overcome the technical difficulties , use ECT automatic control technology , can make the engine working on diesel and gas (or biogas) dual fuel condition , also can achieve transfer between diesel fuel and gas ( when no gas , generator set can work by fuel completely ) . The dual fuel generator sets is started by fuel , with the load increasing , gas amount is also increasing . Under normal working condition , gas can replace 60% to 80% diesel fuel . By this way , not only reduce the running cost , but also reduce the pollution .
