How Does A Propane Generator Work?

By Kyle's Team

how does a propane generator work

When it comes to choosing a generator, there is no shortage of options out there. You might not know how to choose. You should check propane-powered generators, and we want to show you how a propane generator work.

How Does A Propane Generator Work?

In the case of propane generators, they convert motorized power into electrical energy. But how does it do that?

When you run a propane generator, the propane burns to create both energy and heat. It does that with the use of a specialized carburetor.

The carburetor blends measured amounts of air and fuel. It then injects that mixture into the cylinders of the engine.

The piston pressurizes the air and fuel mixture into the combustion chamber. The spark plug then ignites, which drives the piston downward to turn the crankshaft. The crankshaft will then spin the rotor of the generator within its electromagnetic field.

How much electricity your propane generator outputs, what it can power, and for how long depends on its size.

Why Are Propane Generators Rated As Clean Air Generators?

Occurring gas releases no harmful gases or substances when you use it. But, we will discuss this a little later in the article.

In short, propane-powered generators create electricity by transforming motorized power caused by the combustion of propane.

What Is The Run Time Of A Propane Generator?

There is no shelf-life in propane. You can stock up on your fuel supply and save it for rainy days.

You can have a one-pound tank of propane or as large as a four hundred-and-twenty-pound tank. With a propane tank of standard size installed, you can run your generator with no interruption to your power for days. You will not need to refill it manually like you would a gas or diesel generator.

But, of course, how long your propane lasts will depend on the electricity load your generator has to cover. Heating and cooling systems are necessary for survival.

But a hair dryer or coffee maker are not what I would consider essential.

The standby-type propane generator is much larger and fixed. It will supply electricity for longer periods than the portable type (days at a time). That’s because of their connection to a large fuel storage underground.

Of course, if you do not have underground storage for your fuel, you can also connect your generator to a regular propane tank. But these are whole-house generators, and it will take more than a few gallons to keep them running for long periods.

How Does A Propane Generator Work – Manual vs Automatic

Another thing to consider when getting a propane generator is whether you prefer automatic or manual.

With manual propane-powered generators, you have to turn them on yourself.

The Shelf Life Of Propane Limitless

A generator is not something the average person uses every day. It usually sits there until the power goes out, or we need to use it for something specific. As such, it sits there, and so does the fuel used to run it.

Unlike other forms of fuel, which have an expiry date, propane has no limit to how long you can keep it in storage.

Gasoline has a shelf life of three to six months under the right conditions. You have to use an airtight container to store it, and you also should add a stabilizer to your supply to ensure it remains usable.

Without proper storage, gas becomes murky. It may look a little cloudy as well, or like it has a layer of water in it.

Diesel will last longer on the shelf, going up to twelve months. The storage area has to be dry. It must remain at a specific temperature – 70 degrees Fahrenheit. And you also have to add stabilizers and biocides to keep it usable.

Without proper storage, diesel becomes like a gel. It can also grow fungus and develop sediments.

But this is not the case with propane. You have no reason to outfit your propane generator to survive the winter. And you also will not have to add any stabilizers to keep it usable.

Inside the generator is a water and ammonia mixture that responds to raised temperature.

combustion engines that use ammonia have a slower chemical response rate than other fuels.

But as the mixture reaches the burning point, it creates ammonia gas. And this slow rate of the chemical reaction allows ammonia to leave the engine through the exhaust without burning.

Propane is a natural, clean-burning fuel. That makes them more reliable and last longer.

Do not use them inside any building – not even the garage as the carbon monoxide can escape. It does not matter that propane is a naturally occurring gas. Carbon monoxide poisoning can cause death.

Propane Is Readily Available

Generators powered by fuel are useless without the substance that gets them going. In the event of certain disasters, gas and diesel may be harder to come by.

Propane generator users will have less difficulty getting natural gas for a few reasons.

  • The gas lines run underground.
    That means you can run a gas line to your standby/wholehouse propane generator and never have to worry about resupplying.
  • The lines are storm and windproof.
  • You can get propane tanks anywhere selling gas grills.
  • You can even have the tanks delivered to your property.
  • You can use tank monitors.
    Once installed, these monitors will keep track of your fuel levels. They will alert your supplier and you when your supply runs lows.

What Is The Cost Of Running A Propane Generator?

There is no denying that the initial setup of a propane generator will be more costly than gas or diesel.

The equipment alone costs more.

But, remember, a generator might not be a tool you need to use every day. Gas and diesel need proper storage. And even with your best efforts, your gas or diesel can still fail.

The second thing is to put propane in your gas generator and power your home with it. It will take some tinkering. Research to do this project yourself and enjoy the benefits of propane generators without the extra expense.

Or, you can buy a generator that works using both propane and gasoline. There is a gasoline tank for petrol but there is also an inlet to connect a line for propane.

Conclusion

More and more, we watch the world move away from oil-based fuels to more natural alternatives.
