Comparing diesel generators and gas generators

In this article we show you the differences between gas generators and diesel generators.

Natural gas can be used in emergency power generators, continuous operation mode and cogeneration and is considered to be one of the most affordable and effective fuels among non-renewable resources for power generation. In terms of costs, coal is the only fuel that can be cheaper than natural gas, but which, because of its highly polluting properties, is not considered as an alternative. Thus, the main advantages of a natural gas generator are its low cost of operation and use compared to diesel generators, in addition to low emissions.

Natural gas is a fuel obtained in liquid form through drilling into the soil which is subsequently converted into gaseous form and then made available to the populations through pipelines and cylinders containers.

In terms of installation, a natural gas powered generator has installation needs very similar to a diesel powered generator. In fact, the main difference between both generators is the fuel and the form of storage and accessibility of the same.

Natural gas generators are mostly applied in areas that have uninterrupted and constant supply of this fuel through a dedicated network and where the generators have recurrent and continuous use. But in addition to the advantages described above, natural gas generators also have several disadvantages.

Find out the main advantages and disadvantages of the use of natural gas in the operation of a generator:

Main advantages of gas generators:

  • One of the advantages is that it is a cleaner fuel, cheaper than other non-renewable fuels;
  • When compared to other fossil fuels, such as coal, diesel and gasoline, emission levels are much lower. One of the direct consequences is that the odor of leaks is negligible;
  • Another advantage of natural gas generators is their easy use and adaptation to thermal reuse, such as cogeneration (steam, hot water or oil heating);

Main disadvantages of gas generators:

  • Your installation must be done in a location with a natural gas distribution network available.
  • In the event of disasters or natural disasters the supply systems can affect the availability of the network as it can not be stored near the generator;
  • Natural gas has a higher risk of fire when compared to diesel;
  • The engine and control system are more demanding, so it affects the final price of the product, making it more expensive when compared to diesel generators;

Diesel Generators

The diesel generator sets popularly referred to as diesel generators can typically be divided into two basic parts: a diesel engine and an electric generator. Diesel generators can be used to provide power in locations that do not have a utility grid or as backup in an emergency.

This type of generators are available both in single phase and three phase, and can be applied in offices, hospitals, industries, homes, telecommunications towers, among many other applications.

Main advantages of diesel generators:

  • The great advantages of diesel generators are their portability and ease of access to the fuel;
  • Maintenance costs for generators running continuously are lower in diesel generators.
  • It is important to note the lower flammability of diesel compared to other sources of fuel;

Main disadvantages of diesel generators:

Finally, diesel has high emission levels, which in order to comply with the current legislation makes the diesel generator with additional filtering system more expensive.

Conclusion

While both gas generators and diesel generators have advantages and disadvantages, it is important to realize which type of product best fits your business needs.
