GAS GENERATORS · NATURAL GAS · LPG · PROJECT POWER

GAS QUALITY CHANGES THE GENERATOR YOU CAN ACTUALLY USE.

The real decision is not only rated kW. Fuel composition, gas pressure, site conditions, duty and control strategy determine usable output and stable operation.

01 / APPLICATION FIT

WHEN DOES GAS POWER MAKE COMMERCIAL AND TECHNICAL SENSE?

Natural Gas AvailablePipeline supply or a stable on-site gas source.
Long Running HoursPrime or continuous applications where fuel economics matter.
LPG / Biogas / Variable FuelProjects where fuel chemistry and engine calibration must be understood.
Project / System PowerGenerator integration with ATS, synchronizing, switchgear or monitoring.
Short emergency backup with uncertain gas supply may not justify a Gas architecture. Compare Diesel →
02 / FIRST ENGINEERING INPUT

DO NOT CHOOSE THE GENERATOR BEFORE YOU UNDERSTAND THE FUEL.

Four variables should be defined before supplier comparison.

Gas CompositionPressure RangeHeating ValueSupply Stability
01Gas CompositionWhat fuel is actually supplied?
02Pressure RangeCan supply remain stable under load?
03Heating ValueHow much usable energy is available?
04Supply StabilityWill the fuel condition stay consistent?

03 / COMBUSTION STABILITY

OUTPUT STABILITY STARTS WITH COMBUSTION STABILITY.

Air-Fuel RatioCorrect mixture under changing load.
Lambda ControlFeedback for combustion correction where applicable.
Ignition TimingMatched to fuel characteristics and operating condition.
Knock ControlProtection against abnormal combustion.
04 / USABLE OUTPUT

RATED OUTPUT IS NOT AUTOMATICALLY USABLE SITE OUTPUT.

Ambient temperature, altitude, fuel quality, pressure, ventilation and load profile can all change what the site can actually use.

05 / DUTY BASIS

THE SAME kW LABEL DOES NOT MEAN THE SAME DUTY CAPABILITY.

STANDBY

Emergency / limited-duration backup.

PRIME

Extended operation with variable load.

CONTINUOUS

Defined steady load for long-duration operation.

Duty affects cooling, engine loading, service interval, alternator margin and warranty basis.

06 / GAS TRAIN

THE ENGINE CANNOT CONTROL A FUEL SUPPLY THAT THE SITE DOES NOT DELIVER.

08 / FACTORY TEST vs SITE COMMISSIONING

A GAS GENERATOR CANNOT BE FULLY VALIDATED WITHOUT THE SITE CONDITIONS.

BEFORE SHIPMENT

  • Configuration check
  • Controller / protection
  • Load test
  • Electrical output
  • Leakage / assembly
  • Documentation

SITE COMMISSIONING

  • Gas pressure
  • Gas quality
  • Ventilation / exhaust
  • Load behavior
  • Synchronizing
  • Alarm / protection verification

Factory Test → Site Commissioning → Accepted Operation

09 / AFTER DELIVERY

WITHOUT OPERATING DATA, WARRANTY DISCUSSIONS BECOME ARGUMENTS.

Operating evidence helps separate product defect from fuel, site and maintenance causes.
