How Fuel Gas Generators Work

Fuel Gas Generators Parts

Fuel gas generators are machines that turn the chemical energy in gaseous fuels into electricity. They rely on several key components to work efficiently.

At the core is an internal combustion engine designed to use fuels like natural gas, propane, or biogas. Inside this engine, cylinders mix the fuel gas with air. A spark plug ignites this mix, causing small explosions.

These explosions release energy that drives pistons inside the cylinders. The pistons’ up-and-down motion is converted to rotary motion by a crankshaft.

Connected to the crankshaft is an alternator. The alternator has a rotor and a stator. When the crankshaft spins the rotor, it moves within a magnetic field in the stator, creating an alternating current (AC).

An electrical control system converts this AC into usable electricity. It regulates voltage and frequency to ensure a stable power supply. It also manages safety features to protect against issues like low fuel, overheating, and electrical problems.

Fuel gas generators often include automatic startup and shutdown features for ease of use and reliability.
