Competency E5: Select Gas Burners
Gas burners can be either mechanical or non-mechanical depending on how the combustion air is being supplied. Non-mechanical or “atmospheric burners” rely on atmospheric pressure to supply the required combustion air. This learning competency will focus primarily on atmospheric burners.
Although a greater number of gas appliances are moving towards mechanical burners to achieve higher efficiency standards the fundamentals characteristics of atmospheric burners are relevant to all burner types. Many residential and commercial gas-fired equipment are stilled equipped with an atmospheric burner because of their simple operation and low cost.
You must clearly understand how an atmospheric burner operates — and how to adjust it — so that it operates safely and efficiently, meeting the manufacturer’s specifications and the requirements of local gas authorities.
Learning Objectives
After completing the learning tasks in this Competency, you will be able to:
- Use burner terminology to describe different types of burners and their characteristics.
- Describe types of atmospheric burners
- Describe and select burner orifices
