Gas Fitter Practice Test

What type of burner is used in conversion burners?

1. Ribbon burner

2. Flash burner

3. Purge burner

4. Inshot burner

The correct answer is: Inshot burner

In the context of conversion burners, inshot burners are specifically designed to operate effectively with gas fuels while accommodating the design of existing oil-burning appliances. These burners have the capability to mix air and gas before the combustion process, allowing for better fuel efficiency and cleaner combustion. This design allows for a smooth transition from oil to gas, making it an important option for facilities that are switching their heating systems. Inshot burners utilize a unique mechanism where the gas is injected into the combustion chamber, and the velocity of the intake air contributes to the mixing, ensuring thorough combustion. This type of burner is commonly used in conversion scenarios because it can easily be adapted to fit the profile of different appliances, maintaining safety and performance standards. Other types of burners, like ribbon, flash, and purge burners, serve different purposes in gas appliances and system designs. Ribbon burners typically create a flat flame and are used more for specific industrial applications. Flash burners usually operate at very high temperatures and are often utilized in processes that require rapid heat output, whereas purge burners are mainly used in safety protocols to clear any gas prior to ignition. These variations highlight the specific advantages inshot burners hold for those converting from oil to gas systems.
