Functions of the primary air damper and secondary air damper in the heating furnace
Thread Content
What are the functions of the primary air damper and secondary air damper in a heating furnace? As title
The primary air damper regulates the amount of primary air, while the secondary air damper regulates the amount of secondary air. Primary air provides the oxygen required for burning, while secondary air cools the furnace walls.
This varies depending on the construction and naming of stoves in different places
Secondary air is primarily used to lower the flame temperature and to ensure complete combustion of the gas; it is generally employed in heat treatment furnaces, while heating furnaces rarely use secondary air. The use of secondary air results in higher energy consumption.
