How Does An Industrial Generator Work?
An electric generator is a machine that transforms mechanical energy obtained from an external source into electrical energy as the output.
It’s critical to realize that a generator merely “creates” electrical energy. Instead, it forces the electric charges present in the wire of its windings through an external electric circuit using the mechanical energy provided to it. The generator’s output electric current is represented by this flow of electrical charges.
This mechanism can be understood if the generator is compared to a water pump, which induces the flow of water but does not actually “create” the water flowing through it.
The modern generator operates on the electromagnetic induction theory that Michael Faraday first proposed in 1831-32. By moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field, Faraday found that the above flow of electric charges could be induced.
This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, thus generating electric current.
Components of An Industrial Generator
To help you gain a better understanding of how an industrial generator works, we’ll take a closer look at the essential generator components and examine the role each plays in its operation:
- Engine: The generator’s energy source is its engine, which can produce more power the bigger it is. Generators can run on a variety of fuels, including diesel, natural gas, gasoline, or propane, depending on the design.
- Alternator: The process of converting mechanical energy into electrical energy takes place in the alternator, also known as the generator head. The alternator’s combination of stationary and moving components causes the electrons to move.
- Fuel system: The fuel system consists of a tank that can typically hold six to eight hours’ worth of fuel, a fuel pump, a pipe connecting the tank to the engine, and a return pipe.
- Voltage regulator: This device controls the voltage of the electricity produced during generation and facilitates the conversion from AC to DC when necessary.
- Cooling and exhaust systems: While the exhaust system removes and discards the toxic fumes, the cooling system keeps the generator from overheating while it is running.
- Lubricating system: This system stores and distributes the engine oil necessary for a generator engine’s many moving parts to function smoothly and to last a long time.
- Battery charger: Despite using a fuel source to run, industrial generators need battery power to start. The charger makes sure the battery receives the required float voltage to maintain a sufficient charge.
- Control panel: The control, which oversees each aspect of the generator’s operation, acts as its nerve center. According to the generator model, features like engine and generator gauges, phase selector switches, and engine control switches may be present on the control panel.
- Main assembly/frame: The frame provides the structure for the generator and houses and protects its vital components.
Types of Industrial Generators
Industrial generators are very dissimilar from domestic models. These generators must endure heavy use over an extended period of time in unfavorable circumstances. Industrial generators come in a variety of shapes and sizes, with outputs ranging from 150 hp to 4000 hp engines and sizes from 20 kW to 2500 kW.
To maximize usage for your industrial needs, you must choose the appropriate type.
Diesel engines are noted for durability, long life, and normally lower maintenance. A diesel engine running at 1800 rpm can go anywhere between 12,000 and 30,000 hours between major maintenance procedures. After 6,000 to 10,000 hours of use, the same gas-powered engine might require significant maintenance.
Diesel fuel burns more slowly than gasoline, which results in less heat and less engine wear. Due to the higher energy density and higher efficiency of diesel fuel, power generated by diesel generators can also be produced at a lower cost.
While diesel was formally a “dirty” fuel, improvements in engine technology have reduced diesel emissions. Typically, regular diesel engines can run safely with biodiesel blends up to 20%.
Natural Gas Generators
Generators that run on natural gas can be propane- or LPG-powered. Natural gas offers the advantage of easy storage in below or above-ground tanks. Additionally, it burns cleanly, which lessens emissions-related issues. Although they can be more expensive initially, natural gas-powered generators are dependable.
While natural gas is often less expensive than other fuels, it must be trucked to your facility, which can increase the operating costs. Compared to a diesel generator of comparable size, a natural gas generator produces less power.
To achieve the same results, you might need to go up a size. Technology companies make a great choice in natural gas generators as backup power sources.
Typically, gasoline-powered generators are less expensive to buy. While gas generators can run continuously, they do require more thorough maintenance. Rubber parts deteriorate in the presence of gasoline, hastening engine wear.
Due to a higher chance of fire or explosion, storing gasoline is more challenging. Long-term storage is not recommended because the gasoline itself degrades. Larger industrial applications don’t lend themselves well to gasoline generators.
Portable Industrial Generators
It’s not possible to simply pull a portable industrial generator along behind you as you walk; instead, these generators are trailer-mounted models. Large portable generators make an excellent choice for use on construction sites before an electrical supply is established.
These are also frequently used by emergency responders when a large amount of power is needed on location.
Commercial or industrial-grade marine generators are designed to withstand rugged environmental conditions. Among the companies that produce generators specifically for marine use are Caterpillar, Kohler, and Cummins.
Large vessels or oil rigs should use this kind of generator, which is necessary for use close to salt water. Diesel is the preferred fuel for industrial use even though marine generators are also available with gas or diesel power.
Heavy Fuel Oil Generators
Heavy fuel oil generators offer significant fuel savings over the cost of diesel fuel. The overall generator size can often be smaller due to the use of a small higher speed engine. One producer of heavy fuel oil generators is Wartsila.
When choosing this kind of generator, it is important to take into account the availability of heavy fuel oil since this fuel falls into the category of number 5 or 6 fuel oil.
What Precautions Should You Take While Using a Generator?
A generator’s toxic engine exhaust contains carbon monoxide, a potent poison that can be fatal. To protect yourself and others around you from the same, it is crucial that you place the generator in an open area, or in an area with ample ventilation.
Electric shock or electrocution is another potential risk. Make sure the generator is kept in a spotless, dry location away from the elements so as to prevent injury.
What Happens When a Generator is Turned On?
The mechanical energy provided by the fuel source is used by the generator when it is turned on to force the movement of electric charges through an external electric circuit. Therefore, it can be said that the generator simply converts mechanical energy into electrical energy rather than producing electrical energy itself!
What is the Importance of a Control Panel in a Generator?
The user interface for the generator is the Control Panel. It offers provisions for all electrical outlets and controls. Some of the most important functions that the control panel offers include:
- Electric start and shut-down
- Engine Gauges
- Generator Gauges
- Phase selector switch, frequency switch, and engine control switch
What Would Cause a Generator Not to Produce Power?
A generator’s inability to produce power is primarily caused by a loss of residual magnetism. This results from the generator going unused for an extended period of time. It can also happen when the generator is left on for a significantly long period of time without plugging anything into it.
