LNG Nozzle Introduction

I. Overview

An LNG Nozzle, also known as a LNG Dispensing Nozzle or LNG Filling Gun, is a specialized device used in the handling and dispensing of Liquefied Natural Gas (LNG). It plays a crucial role in ensuring the safe and efficient transfer of LNG from storage tanks to vehicles or other end-use applications.

II. Key Components and Functionality

  • High-Pressure Oxygen Nozzle: The LNG nozzle typically features a high-pressure oxygen nozzle positioned at the center. This nozzle is responsible for delivering the oxygen required for the combustion process.

  • LNG Passing Nozzles: Surrounding the oxygen nozzle are multiple LNG passing nozzles, which release the liquefied natural gas into the combustion chamber. These nozzles are designed to optimize the mixing of LNG and oxygen for efficient combustion.

  • Preheating Oxygen Nozzles: Preheating oxygen nozzles are positioned in the outer part of the LNG passing nozzles. They provide additional oxygen to aid in the preheating and ignition of the LNG, ensuring a smooth and controlled combustion process.

III. Technical Specifications

  • Diameter: The diameter of the high-pressure oxygen nozzle is typically 15 mm. The LNG passing nozzles may vary in diameter, with some models featuring six nozzles with a diameter of 5 mm in the upper side and three double nozzles with outer diameter of 4 mm and inner diameter of 2 mm in the lower side.

  • Material: LNG nozzles are constructed from materials that can withstand the extreme cold temperatures of LNG. This includes stainless steel and other alloys that are specifically designed for cryogenic applications.

  • Spring Energized Seals: Some LNG nozzles utilize spring energized seals, such as the LNG Lip Seal, to ensure a tight and secure connection between the nozzle and the filling receptacle. These seals are made from imported polymer material that is reinforced for ultra-low temperature environments.

IV. Applications

  • LNG Filling Stations: LNG nozzles are primarily used in LNG filling stations, where they are attached to storage tanks and used to dispense LNG into vehicles such as trucks, buses, and ships.

  • Industrial Applications: In addition to transportation, LNG nozzles may also be used in industrial applications where LNG is used as a fuel or raw material.

V. Conclusion

In summary, the LNG Nozzle is a specialized device that plays a vital role in the safe and efficient transfer of liquefied natural gas. Its key components and technical specifications ensure optimal performance in a variety of applications, from LNG filling stations to industrial uses.
