Introduction to gas generator sets

Gas generator sets are electrical energy generating systems that use natural gas, liquefied petroleum gas (LPG) or other fuel gases as the primary source of energy to power a heat engine coupled to an electric generator. These equipment are widely used for backup power generation as well as continuous applications where grid power supply is unreliable or unavailable.

This type of generating sets is characterized by its efficiency, lower environmental impact compared to diesel generating sets and its ability to operate with gaseous fuels that are usually cleaner and more economical. Their versatility has made them a preferred option in industrial, commercial and residential sectors.

Main components

A gas generating set is fundamentally composed of an internal combustion engine designed to run on fuel gas, an electric generator coupled directly to the engine, and a control system that regulates the operation of the set. In addition, it includes auxiliary systems such as the gas supply system, cooling system, exhaust system and control panels.

The gas engine transforms the chemical energy of the fuel into mechanical energy through controlled combustion within the cylinders. This mechanical energy is transmitted to the generator, which converts the rotary motion into alternating current electrical energy suitable for immediate use or storage.

The control system monitors essential parameters such as revolutions per minute, temperature, oil pressure and fuel level, ensuring safe and efficient operation, as well as facilitating automatic start in the event of external power failure.

Energy conversion process

The process begins with the injection of fuel gas into the engine's combustion chamber, where it is mixed with air in an optimal proportion for combustion. Spark or compression in specific engines ignites this mixture, generating an expansion of gases that moves the pistons.
