Overview of basic principles

The ignition of industrial burner or burner generally adopts the electrode ignition method, which is to put two electrodes in the gas and release a certain amount of energy by firing an electric spark through high voltage electricity to ignite the gas. At present, some burners use one electrode ignition and replace the low-voltage end with an ignition column.

The specific work process:

1. Generation of a high-voltage arc When the ignition power supply is applied to the ignition electrode, it generates a high-voltage arc.

This arc breaks through the surrounding air, producing sparks. The electrodes, typically made of metals or alloys such as tungsten and chromium, must have excellent conductivity and heat resistance to withstand high current density and high-temperature conditions. These electrodes can be in the form of rods, sheets, or wires.

2. Ignition of fuel The sparks generated spread to the fuel and air, igniting the fuel.

As the fuel burns, oxygen in the equipment is consumed, forming combustion products like carbon dioxide and water vapor, ensuring complete combustion.

3. Combustion phase

The process from ignition to complete combustion can be roughly divided into two stages. Initially, the electric spark heats the combustible mixture, causing localized ignition and forming an initial flame center. This initial flame then spreads to the unignited mixture, initiating combustion. If the initial flame center forms and the flame spreads stably, the ignition is considered successful.

The formation of the initial flame center depends on the gas concentration, pressure, initial temperature, flow state, mixture properties, and the energy provided by the electric spark in the electrode gap. This involves selecting the right high-pressure pack and using the appropriate electrodes. Different power burners or burners for different gases require different high-pressure packs, and there are significant price differences among these packs. Additionally, the choice of electrode material is crucial; the ignition efficiency can vary greatly when using the same high-pressure pack with different electrodes.
