A Fuel Gas DLN (Dry Low NOx) Skid equipped with filters typically incorporates various types of filtration systems to ensure the quality and cleanliness of the fuel gas supplied to the combustion system. The specific filters used can vary based on the application and the requirements, but here are some common types of filters that may be included:

  • Coalescer Filters: Coalescer filters are designed to remove liquid contaminants, such as water and hydrocarbons, from the fuel gas stream. They work by merging small liquid droplets into larger ones, making it easier to separate and remove them from the gas. Coalescer filters are essential for preventing liquid contaminants from entering the combustion system, as they can disrupt combustion and cause equipment damage.
  • Particulate Filters: Particulate filters, or solid particle cartridges, are used to capture and remove solid contaminants, such as dust, dirt, and particulate matter, from the fuel gas. These filters prevent solid particles from clogging fuel nozzles and causing damage to downstream equipment.
  • Micron Filters: Micron filters are used to remove fine particulate matter and contaminants of a specific size from the fuel gas. These filters are capable of trapping very small particles to ensure the gas is clean and free of impurities.
  • Molecular Sieve Dehydrators: Molecular sieve dehydrators are used to remove moisture from the fuel gas. Removing water vapor from the gas is crucial because excess moisture can cause combustion issues and corrosion in the combustion system.
  • Carbon Filters: Carbon filters are used to remove hydrocarbon vapors and other volatile organic compounds (VOCs) from the fuel gas. These filters are important for maintaining the quality of the gas and preventing the release of harmful emissions.

The combination of these filter types in a Fuel Gas DLN Skid ensures that the fuel gas is free from liquid, solid, and gaseous contaminants, thereby optimizing the combustion process and protecting downstream equipment. The specific design and arrangement of these filters can be customized to suit the requirements of the specific application, the type of fuel gas used, and the environmental conditions.

Proper maintenance and monitoring of these filtration systems are essential to ensure they continue to function effectively in maintaining a clean and reliable fuel supply to the combustion system while meeting emission and operational standards.
