Powergen Dual Fuel Conversion Kit

What is Dual Fuel: -

Dual Fuelling is simultaneous combustion Methane rich gas (most often Natural gas) with Diesel as fuel.
After conversion, the engine can continue to operate with only Diesel also. However, a ‘Gas only’ operation is not possible.
During Dual Fuel operation, a reduced quantity of diesel fuel acts as the ignition source for the air-gas mixture.
The Methane rich gas mix replaces significant proportion of Diesel to produce equivalent heat energy during combustion in the cylinder.

Benefits of dual fuel engines: -

Flexibility - Can be operated on only diesel in case of non-availability of gas. In case of any DF fault, only DF controller shut off the gas supply and genset will run on diesel only mode.
Field conversion is possible from diesel to dual fuel.
Reduce the cost of generation - Dual fuel engines deliver financial savings through reduced diesel fuel consumption. Gas is Cheaper than Diesel.
Environment protection compared to Diesel engine - Due to clean burning characteristics of Natural Gas, exhaust is cleaner.
No power loses or deration - Higher specific power output compared to gas engine and same as diesel engine.
Nationwide service network.
Low capital cost compared to gas engine
Note :- At any time, Dual fuel converted engine can’t be operated with Gas exclusively (100%)

Dual Fuel Working Principle:-

The Natural gas used for Dual Fuelling is sourced from either piped gas or from local storage.
It is injected into the combustion air stream via a Gas Train consisting of a gas filter, gas pressure regulators and a solenoid valve.
A flow control valve at the end of the train controls the proportion of the gas injected through a gas mixture unit.
The gas train is designed to accept input gas at low pressure and deliver it to the engine at a slightly negative pressure.
In dual fuel mode, natural gas is introduced into the engine’s intake system.
The air-to-natural gas mixture is then drawn into the cylinder, just as it would be in a spark-ignited engine, but with a leaner air-to-fuel ratio.
Near the end of the compression stroke, diesel fuel is injected and ignites, causing the natural gas to burn.
A dual fuel engine can operate on 100 percent diesel fuel or the substitution mixture of diesel and natural gas
It delivers the same power density, torque curve and transient response as the base diesel engine.

Dual Fuel Kit Scope components:-

Gas Train: -

Gas filter, Pressure regulator, Gas Pressure Gauge, Zero Pressure regulator, Gas shutoff valve and Gas flow adjusting valve
Gas piping from gas train to Gas mixer and Gas mixer unit (depends on number of Turbocharger in engine – same qty as Turbo

Mixer:-

Dual Fuel System delivers fuel gas to the combustion cylinders via the Gas Train into a special Air-Gas Mixer.
The mixer is installed on the engine air inlet before the Turbo charger.
Combustion is commenced by Diesel as the ignition source and followed by ignition of the Gas

Sensors:-

Gas pressure sensor and Boost pressure sensor
Exhaust gas temperature sensor/s and Intake manifold temperature sensor
Vibration sensor/s

Control Panel

Controller continuously monitors critical engine parameters through the operation and transitions.
It provides safety to the engine while operating in the Dual-fuel mode.
PLC, input / output units
HMI and switches / buttons/ wirings etc
Remote monitoring system - Optional with 3 months free subscription

Dual Fuel Installation requirements:

Gas pipeline connection should be near to Genset, around 6’ space required for installing our kit. Below are the minimum pipe size and model wise end flange chart with an isolation valve. – Customer Scope
