Gas Engine Generator Set

In its most basic form, a gas engine generator set (genset) is an energy-producing machine consisting of a gas engine and an alternator or electric generator. A gas-powered generator set can provide electricity in areas without a grid or with a bad one.

You will be able to find a wide variety of Gas Engine Generator Set Products, Service Providers, Suppliers and Companies by simply following Linquip's suggestions.

There are differences between natural gas-powered generators, which produce electricity continuously, and diesel generators, which are generally used only during blackouts.

Basics of Gas Engine Generator Sets

A genset is often used in areas that are not connected to the power grid, as well as places where power outages are common or in places where outages can be especially dangerous or significant, such as deep within a mine. During peak usage hours, they may be used as either a primary or supplementary power source.

Gensets are made up of an engine (as a prime mover) and an alternator. An engine transforms the chemical energy of the fuel into mechanical energy. Using mechanical energy, the alternator rotor spins and converts mechanical energy into electrical energy. A rotor and a stator are the two main parts of an alternator. As a result of the phenomenon of electromagnetic induction, when the alternator rotor spins through the magnetic field between the rotor and stator, a voltage is generated in the alternator stator. As soon as the stator voltage is connected to a load, current flows, and power is produced.

In addition to its low energy production costs compared to other fuel forms, its continuous high performance, and the option of upgrading gas-powered sets to cogeneration and regeneration sets, natural gas-powered packs are preferred by a wide range of industries.

Working principle of Gas Internal Combustion Generator

Generally, prime movers use gas or biogas, which is primarily composed of CH4. After fuel gas and air have been mixed into the cylinder, a high-voltage spark plug ignites and explodes the gas, the piston moves the crankshaft, and the crankshaft and generator are connected to power the generator.

Due to the pre-mixing of air and gas upstream of the turbocharger, the gas internal combustion engine can operate at a lower supply pressure.

These steps describe how a natural gas generator provides electricity to other appliances:

  • Injection
  • Ignition
  • Electricity generation

Injection

The piston compresses fuel and air mixture in the combustion chamber of the internal combustion engine.

Ignition

When the piston compresses the mixture of air and fuel, a spark plug ignites it with a small but powerful spark. During the ignition of the spark, an explosion occurs in the chamber, converting the explosion into mechanical energy.

Electricity Generation

The combustion process pushes the piston down with sufficient force to turn the crankshaft, causing the rotor to spin. During the spinning of the rotor, the stator wires conduct electricity and combine to create a single large electrical current which, when large enough, can power appliances.

Advantages of Natural Gas Generators

Investing in a natural gas generator means you'll always have a machine you can rely on when the power goes out.

Generally Low Cost

As compared to comparable diesel generators, natural gas generators typically have lower upfront costs. You will also be able to maintain low operating costs for the duration of your generator's life since natural gas fuel typically costs less than diesel fuel.

High Fuel Supply

With a natural gas generator connected to your local gas pipeline, you don't have to continuously refill your fuel tank, giving you virtually unlimited fuel supply, assuming no major disasters or utility outages occur. The fuel for diesel generators must be polished to remove contaminants, which takes extra time and money. With natural gas, you can tap into the local supply directly rather than relying on diesel's limited shelf life in storage.

Low Emissions

There are fewer toxins released into the atmosphere after burning natural gas than when burning other fossil fuels.

Quiet Running Sounds

The quiet operation of natural gas generators makes them ideal for applications such as generator rooms or noise-ordinance-restricted areas.

Application of Gas Internal Combustion Generator

According to the mode of operation of a gas internal combustion generator set and of a mains supply, there are three main types: island mode, a grid without Internet, and online selling of electricity.

Island Mode

There is no connection between the generator set and the mains.

Grid Connection But Have No Access to the Internet

Through the parallel cabinet, the generator set and the mains share the load, but the total load exceeds the generator set's output power, so the generator set cannot send power to the grid.

Online Electricity Sales

The load is shared between the generator and the mains. They are connected to the grid via the parallel cabinet. The system load is less than the generator set output power. It is possible to sell back excess electricity to the grid.

How Do I Choose the Right Natural Gas Generator for My Needs?

When you decide to go the natural gas route, you'll need to find the right generator for your business. When evaluating your options, consider the following specifications:

Emissions Rating

U.S. EPA guidelines and regulations help reduce harmful emissions polluting the environment. As new generators have become more environmentally friendly, regulations have become stricter over the past few decades. As you search for the best generator, make sure it meets the latest EPA criteria since different types of generators must adhere to different ratings. If you live on the West Coast, such as in California, you should look for CARB-certified natural gas generators.

Phases

There are two types of generators, single-phase and three-phase. Both use alternating current (AC), but single-phase models supply one flow of AC, while three-phase models generate three oscillating flows to provide more power and longer power output.

Size

The size of your generator is essential to ensuring you have enough power for your projects. Overloading a generator that's too small for your needs could result in damage to the generator and appliances connected to it as well as the possibility of a fire.

Sound Enclosure

Despite the fact that gas generators run quieter than other types, there is still the option of creating a quieter environment and not being exposed to constant generator sounds, which can cause hearing damage. Using sound-attenuated enclosures, you can reduce the noise output of the generator if you are installing it in an area that needs to remain quiet.

How To Size a Gas Generator?

Choosing the right size for your natural gas generator depends on the efficiency of the machine. If your generator is too big, it will waste energy, while if it is too small, it will quickly become overloaded. In addition to the size, you'll need to consider the following:

Function

When shopping for a generator, consider why you need it and how often you will use it. Decide which appliances must be powered during an outage and find a generator that can handle them.

Fuel Supply

Consider a generator with a smaller fuel requirement if you have a limited amount of natural gas at your location.

Generator Room

You'll need to determine how much space you have for the generator. Also, depending on the generator voltage, you'll need to comply with the generator room regulations to ensure the generator operates safely.
