Depending upon the actual operating conditions, the Zeeco AK series of burners are generally used for applications where the gas NOx emissions can be approximately 50ppmv or greater and the oil NOx emissions approximately 175ppmv.
The Zeeco AK series of burners is provided with a side air entry configuration. The Zeeco AK series of burners can be used in natural or forced draft type applications.
Typically each burner is provided with an individual plenum, but there are also versions available for mounting in a common plenum. The standard burner is designed to achieve a noise level of 85 dBa but if required, much lower noise levels can be achieved by designing with alternative materials. Typically, the Zeeco AK series of burners are designed to achieve a 5:1 turndown or greater on gas and 3:1 on oil.
