<h2>Overview of Industrial Burners</h2>
<p>Industrial burners are devices designed to mix fuel with air to produce a stable and controllable flame essential for various industrial heating, melting, and cooking processes. To initiate the combustion process, burners rely on ignition sources like sparks and pilots, thereby necessitating reliable ignition systems.</p>

<h2>The Role of Ignition Transformers</h2>
<p>Ignition transformers, also known as ignition coils, are high-voltage transformers that convert low-voltage electricity from a battery or power source into the high-voltage spark needed for ignition in burners. They function on the principle of electromagnetic induction, which involves passing an electric current through a coil to generate a magnetic field.</p>
<p>Differing in their design and composition, ignition transformers vary to suit specific industrial applications, including their voltage output, size, and energy efficiency. They operate with isolation that ensures the high-voltage side is safe from any interaction with users, enhancing operational safety.</p>
<p>The ignition process starts as the magnetic field collapses rapidly, inducing a voltage boost in the secondary coil. This outcome has higher voltage levels capable of overcoming the air gap between electrodes, culminating in a spark that ignites the fuel-air mixture safely and effectively.</p>
