What Is A Natural Gas Generator – Query Solving Guide

You may be overthinking what a natural gas generator is and how it works, while simultaneously learning how to offer a temporary power supply in the form of electricity to operate all of your fundamental gadgets in an emergency or widespread blackout.

Yesterday was a weekend, which meant spending quality time with family and allowing your work some breathing room in an otherwise frantic schedule.

What Is A Natural Gas Generator

Alternatively, the entire area may be blacked out and without power. What are our options for dealing with this problem? It’s not as difficult as we imagine!

You can click here to know about the different types of generators.

What Is A Natural Gas Generator?

Now is the moment to start. The vast majority of people have used a gas generator.

A gas generator can be a lifeline in various situations, including power outages caused by inclement weather, business maintenance, and household power outages.

While gas generators are beneficial for many of us, particularly in laboratories where they may increase efficiency and safety, even your backup generator may fail at times.

If you lose power due to extreme weather, for example, surrounding gas stations may be affected. You’re left without power and access to your generator in this situation. A portable natural gas generator can help with this.

If you currently own a gasoline generator, you don’t need to purchase a natural gas generator for your home. Conversion kits are available for converting a gas or diesel generator to a natural gas portable generator.

Because natural gas is less expensive than gas or diesel, natural gas generators are becoming more popular as backup generators during disasters.

 Now let’s look at how gas generators work and the mechanisms, advantages, and disadvantages.

· Types Of Natural Gas Generators

The gas generators are built for the continuous power supply but there are dual fuel or tri-fuel portable gas generators available in the market that gives you the flexibility in choosing fuel you can go with either gasoline or propane fuel in case of dual fuels while the natural gas forms the third variant of fuel as in tri-fuel generators.  Apart from these types based on fuel, there are two standards types of gas generators that are:

  • Standby Generators
  • Prime Generators

Standby generators are the home standby units used in both residential and commercial settings for heavy-duty power needs. These gas generators are usually permanently installed with the gas supply line at home and will continuously deliver power to your household or industrial appliances.

Prime generators on the other hand are rarely used in residential settings and supply continuous large-scale power when the grid power is not available. Prime generators are not permanently installed but are transported to the site on a truck or a wheeler cart whenever and wherever the need arises.

How Does A Natural Gas Generator Work?

A modern or lightly used backup generator for enterprises in any industry is a sensible investment. Natural gas-powered generators have a lot of advantages when it comes to determining which model is ideal for you.

Understanding how natural gas-fired generators function and how they might be beneficial to you is the first step to knowing their components.

Main Components Of The Natural Gas Generator:

Natural generators have a lot of components that, when combined, provide the electricity that your business needs to run its vital appliances and processes. The following are the main components:

  • Fuel
  • Combustion chamber
  • Pistons
  • Spark the plug.
  • Crankshaft
  • Stator
  • Rotor

1. Fuel:

You can quickly obtain a fuel source by hitting your metropolis’s existing natural gas infrastructure.

Design fuel from a town-wide source assures that the generator will have a consistent fuel supply, allowing you to keep your activities running with downtime.

2. Combustion Chamber:

A combustion chamber is an enclosed compartment in which air and other gases are compressed and burned.

3. Propeller:

The engine parts slide back and forth within the combustion chamber, compressing the atmosphere and energy to increase its combustion level by making the space inside bigger or smaller.

4. Sparkle The Pins:

Spark in all the pins, tiny components with electrodes protruding into the explosion compartment.

5. Connecting Rod:

The connecting rod is a component attached to the propeller that translates the pistons’ up-and-down motions into rotating motion, generating electricity.

6. Stationary Cylinder:

This is the stationary cylinder made up of secured wire coils surrounding the electromagnetic field.

7. Rotating Shaft:

This is a rotating electromagnetic shaft inside the stator that assists in generating a strong electrical current.


Generators use mechanical energy, and enlightened natural gas generates electricity. Natural gas generators provide the cleanest fossil fuel electricity possible by drawing methane gas from a direct line pumped by the utility producer or from a tank.

The methane gas generators take the following procedures to generate energy for other equipment.

  • The piston compresses the mixture injected into the chamber, which can be flushed by the internal combustion engine.
  • The sparks of all the pins ignite the fuel with a small, yet intense spark after the piston compresses the air and fuel mixture. The spark causes an outbreak in the chamber, which is converted into mechanical energy and could be a reminder of the generator.
  • The gases expand during ignition, forcing the propeller down hard enough to turn the connecting rod, which subsequently spins the rotor. When the rotating shaft spins, the stationary wires transfer energy and merge into a single huge electrical current that can supply power equipment and structures if the current is large enough.

Natural gas is used instead of other fuels like diesel in a gas generator. Natural gas generators are more efficient and cost-effective than fossil-fueled generators.

Knowing the benefits and drawbacks of natural gas generators will help you decide whether to purchase them.

Sizing A Natural Gas Generator

Choosing a natural gas generator that is the right fit for your needs is as important as choosing the better model. This is because the best gas generator for you is none other than the one that can power all of your desired household appliances and gives you the best performance with the best longevity. But how will you determine this best performance and what is the cut-off for your power needs? Answering these questions will help you significantly in finding the right gas generator.

Size Of Generator:

Since gas generators are intended for whole house power then you would have to calculate the appliances you want to preferably run under power outages. After deciding on the number of appliances, you would have to look for their specific wattage. Check out for both surge and peak wattage and individually add them up. The total wattage will give you an idea of the running or output wattage of the generator. You should go with the generator unit that has a slightly higher running wattage than the wattage you have calculated for your household appliances.

A number Of Power Receptacles:

One of the critical considerations before buying any type of generator is to check out the power circuits on your generator. The number of power circuits will give you an idea of how many devices can be connected to your generator. For example, if you have a generator with 8 power ports or circuits then it means you can connect a maximum of 8 devices with your generator at once.  The type of the device will be based on its wattage. For instance, a 2500 watts portable generator with 8 power circuits will run the following electric devices.

  1. LED light
  2. Fans
  3. Mini Cooler
  4. Microwave
  5. Drill machine
  6. Electric kettle
  7. Mini Fridge
  8. TVs and Laptops

This 2500 watts generator will not be running your heating or cooling system. Nor does it will heavy-duty appliances including the central AC, Gas Furnace, or electric range. If you want to increase the number of basic appliances such as a washer, dryer, or home security system then you would have to go with the gas generator that offers you 2500 watts power but with 10 to 11 power circuits on board.

Similarly, if you want to run the AC or Gas Furnace when the power from the grid supply is not available then you would have to go for a mid-range to heavy-duty generator such as a typically 7.5 KW gas generator for running almost all basic appliances at your home including the central AC and heating systems.

Advantages Of Natural Gas Generator:

Natural gas provides a consistent energy source, particularly during natural catastrophes when power outages are common. It’s a life-saving energy source in an emergency.

Here are some of the advantages of employing natural gas generators for backup power.

1. Fuel Is Less Expensive:

Natural gas costs approximately a tenth of what diesel does. Longer outages and increased demand for diesel fuel can increase the cost.

Natural gas offers longer run periods at a lower cost, and gas utility infrastructure is redundant in many regions, making it a solid emergency fuel source.

2. No Fuel Storage On-Site:

Local jurisdictional clearances are required for on-site storage of diesel fuel.

Many variables particular to site requirements might make diesel fuel storage a difficult and time-consuming task. Natural gas delivered by pipeline avoids these issues. 

3. No Regular Maintenance:

Diesel fuel tanks must be maintained regularly, or the gasoline will go bad. The shelf life of diesel fuel is less than a year: tank, degradation, filter maintenance, microbiological contamination, and water acclimation.

4. Fuel Spill Prevention And Cleanup:

Diesel fuel has the potential to spill and must be disposed of. Human error can result in diesel fuel spills, which can be quite costly.

5. Improved Air Quality:

Natural gas is a clean fuel that emits far less pollution than diesel generators in standby installations.

6. Adaptable Installations:

Natural gas fuel is significantly easier to use in specific situations, such as rooftops, tight spaces, or secure areas where fuel delivery is a technological difficulty.

Disadvantages Of Natural Gas Generators:

Despite their numerous advantages, gas generators have a few disadvantages. The downsides of generators are listed below;

1. Nature Is Toxic:

Natural gas can be lethal. Inhaling significant amounts of gas is quite dangerous. Methane causes asphyxiation. That is, it depletes your oxygen supply and causes death.

2. Extremely Combustible:

Natural gas is a highly explosive substance that can do greater destruction. Natural gas leaks may result in fire explosions in your homes.

Everyone knows that gas is a matter which has no size or shape and cannot be identified by smell unless an odorant is enhanced to it.

3. Emissions Of Greenhouse Gases:

Natural gas contributes to greenhouse gas emissions when burned in inefficient ways, which is unavoidable. The gas is more environmentally benign than other fossil fuels, producing fewer greenhouse emissions since it burns cleaner, yet it still pollutes the environment.

4. Leakage Of A Gas:

Leaks of natural gas are extremely harmful. Even though natural gas is lighter than air and disperses easily, it poses a significant risk because it is colorless, odorless, and tasteless, making identifying a leak difficult

One of the drawbacks of natural gas is that industrial biogas facilities may only be profitable if raw materials are plentiful (food waste, manure).

As a result, bio-methane-derived natural gas is far more acceptable for rural and suburban locations.

Despite the drawbacks, it is noteworthy that the entire natural gas production, processing, transportation, and use cycle has a total energy efficiency of about 90%.

It is the finest choice among fossil fuel energy sources from every standpoint. You might be wondering what the benefits of natural gas are. This has been covered in prior articles.

Natural gas has proven to be more cost-effective than other energy sources, making it more economically viable. It is cost-effective in installation time, physical footprint, and emergency response time.

Many households and businesses that use natural gas generators have benefited from this.


1.   Why Choose A Used Natural Gas Generator?

Buying a secondhand or used gas generator is beneficial for various purposes with the obvious being its discounted price. The used natural gas retailers will opt to give you the maximum discount of up to 70% of the newly purchased item and you can save enormously with used generators. Secondly, the gas generators can be directly connected to the gas supply line and you don’t have to mind the fuel tank levels. Another important factor for considering used goods is the environmental impact which significantly reduced waste by using used or refurbished parts.

2.   What Is The Best Natural Gas Generator For My Needs?

The best natural gas generator for your needs is the most suitable one for your power requirements and to find out which generator is suitable for you, you would have to consider some important specs of the unit. For instance, to determine the best gas generator for your needs, you should look for emission rating, size, sound enclosure and phases of operation, etc. to determine the right product for your needs.

3.   Where Natural Gas Generators Are Used?

Gas generators are designed to fulfill large power needs in the absence or outage of the grid power supply. Therefore, the best places for the use of gas generators are the large facilities with enormous power demands but more importantly the places where continuous power supply is critically needed at all times. Nursing homes, hospitals, commercial units, and such buildings form the common places for gas generators.
