Different refractory materials in the inner rod and outer sleeve balance machinability with high-temperature stability for flame sensing and ignition.

A segmented silicon-carbide electrode uses a harder inner rod and softer outer sleeve to handle burner heat while easing assembly.

An arc-lit ignition powder drop improves exothermic weld startup reliability while keeping users farther from the mold.

A PCB spark gap ignites exothermic welding material without starting powder, improving ignition reliability and lowering igniter cost.

Voltage profiling at the ignition electrodes detects hydrogen flame formation and helps control the burner fuel-air mixture during start-up.

Offsetting the ignition spark outside the primary flame chamber improves hydrogen burner ignition while reducing electrode heat wear.

Ground-level seeding is limited by downwash, wind, and obstacles; an upward fan, tapered body, and rotating support improve vertical and horizontal dispersion.

Heat-resistant burner electrodes can bend under gravity; a stabilizing section improves resistance to deformation and extends service life.

This case uses the burner’s ignition electrode to measure pre-flame voltage change and flag poor spark quality before flame formation.

Adjustable main body extends to access hard-to-reach industrial burners, resolving safety risks from improvised reaching methods.

A portable flame propelling device uses a mechanical pump to move alcohol fuel from a non-pressurized vessel through a nozzle for ignition.

A burner electrode uses a cavity-bearing central section stabilized by internal struts to reduce refractory material consumption.

Secondary nozzle openings on a multi-flame burner generate flames that transmit ignition to adjacent nozzles, preventing unburned fuel accumulation.

A compact pressure regulator adapter controls gas flow from standard fuel canisters to maintain optimal heating temperatures.

A porous evaporation element distributes liquid fuel via capillary action for rapid vaporization.

An electric igniter lance generates a plasma flame within the fuel duct to ignite pulverized biomass or fossil fuels directly.

A heat shrink gun trigger pivots to a loading position, exposing the piezoelectric lighter housing for direct user access.

A tubular burner flame hole member uses two sheet metal plates with a protruding central cylindrical hole to direct the air-gas mixture forward.

Transverse holes in the removable cap create a complex gas path that prevents dirt accumulation and shields the pilot flame from air currents.

A conductive layer grounds a control circuit IC to stabilize substrate potential and reduce electromagnetic noise impact on temperature sensing.

Movable nozzle positioning eliminates part changes, reducing assembly time and costs.

Elastic tightening ring compensates radial pressure to prevent ceramic damage while ensuring a pressure-tight seal against vapor draft leakage.
