What type of burner is most commonly used for residential purposes?

The gun type burner is most commonly used for residential purposes because it is designed to provide efficient combustion and is suitable for a variety of heating applications, such as oil and gas heating systems. This burner type has a compact design and can be easily installed in residential settings. Its ability to produce a stable flame and maintain consistent combustion efficiency makes it a preferred choice among homeowners and professionals.

Moreover, gun type burners are typically adjustable, allowing for better control of the air-to-fuel ratio, which enhances overall performance. This adaptability contributes to their popularity, as they can match different heating demands while ensuring safety and efficiency.

In contrast, other burner types like the rotary type and rotary cup type are more specialized and often used in industrial applications or larger systems due to their different operational requirements and larger fuel capacities. Atmospheric type burners, while used in some residential applications, are less common for heating in comparison to gun type burners due to their specific design characteristics and operational limitations.

Overall, the versatility, efficiency, and reliability of gun type burners make them the leading choice for residential heating systems.
