Swirl-stabilised Burner Having an Inertisation Front and Related Methods

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

This patent describes a burner system that uses a swirl generator to mix an inert process medium with combustion input streams. The system features an 'inertisation front' that keeps the stabilized flame at a controlled position and prevents the ignition of the fuel near the burner openings, enhancing safety and combustion stability.

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

• Industrial furnaces for metal processing
• Gas turbine combustors for power generation
• Industrial boilers requiring stable and safe flame operation
• Chemical process heaters
• Waste incinerators with specific safety or emissions requirements

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced operational safety due to controlled flame stabilization
• Reduced risk of flashback or unwanted ignition in burner systems
• Improved combustion efficiency and stability
• Potential for lower emissions due to optimized flame positioning
• Applicability in environments requiring strict safety and operational control

Patent Abstract

A burner for producing a stabilized flame with an inertisation front upstream from the stabilized flame includes a swirl generator and an inlet device with a passage therethrough. The swirl generator swirls an inert process medium about a swirl axis in a flow direction and one or more openings in the inlet device provide one or more partial mass flows containing combustion educts. The inert process medium inhibits combustion of the combustion educts through the inertisation front to displace the stabilized flame from the one or more openings.
