Spark igniter

Types of Spark Igniter

A spark igniter is a device that produces electric sparks to ignite a combustible gas or a flammable mixture of a gas and air. It consists of an electric circuit with a high voltage that can break down the air in the tiny gap and make a spark jump across the gap. Spark igniters are used in gas ovens, gas burners, and grills.

There are different types of spark igniters, and each has its unique application.

• Continuous Spark Igniters: In this type of spark igniter, the spark plug keeps on firing until the gas ignites. It is commonly used in gas stoves, and the igniter keeps clicking until the burner is lit.
• Intermittent pilot: In this type of spark igniter, the electric spark is pulsed on and off. It is commonly used in gas furnaces and boilers. The spark ignites the pilot light, and once the pilot light is lit, the main gas valve is opened, and the spark is turned off. If the pilot light goes out, the spark igniter reignites it.
• Direct Spark Ignition (DSI): The DSI is commonly used in modern propane and natural gas appliances. The spark igniter directly lights the main gas burner. This type of igniter is energy-efficient and is commonly used in water heaters and other appliances.
• Hot Surface Ignition: A hot surface igniter is used in gas appliances. The igniter has a ceramic rod that heats up to a very high temperature, often more than 1800 degrees Fahrenheit. The heat ignites the gas. This type of igniter is very reliable and has a long life. It is commonly used in gas furnaces and boilers. The hot surface igniter usually has a silicon carbide rod or a silicon nitride rod.
