Thermally Highly Loaded Nozzle

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a thermally high-loadable nozzle designed with an inner pipe for delivering reactants and an outer pipe for active cooling. A special cooling passage with grooves is implemented between the pipes to supply coolant directly at the contact surface, thereby effectively removing heat during operation, especially in high-temperature reaction environments.

Use CasesContent extracted from patent full text and abstract with AI.

• Injection nozzles for reactors in the chemical or petrochemical industries, where high temperatures are expected.
• Combustion systems for efficient fuel delivery and cooling in energy generation plants.
• Nozzles for gasification or pyrolysis reactors in processes involving petroleum, coal, or biomass.
• Specialized burners with high thermal resistance for industrial furnaces or kilns.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved thermal resistance and longevity of the nozzle due to enhanced cooling.
• Reliable operation under high thermal loads, reducing the risk of nozzle failure or damage.
• Increased efficiency and safety in high-temperature processes by maintaining structural integrity.
• Adaptable design for various industrial reaction chambers and processes requiring precise reactant injection and cooling.

Patent Abstract

The nozzle has an outer pipe (1) for a cooling function. An inner pipe (2) is set in outer pipe to supply reactant through nozzle orifice (4) on face surface (5) into a reaction chamber (6). A cooling passage (7) is provided for supplying coolant (8) at contact surface (9) between outer pipe and inner pipe. A groove is formed in cooling passage and inlet opening (10) is set for supplying coolant at nozzle shaft. An outlet opening (12) is formed for removing coolant from nozzle shaft and nozzle orifice.
