Heating furnace mixing damper
Thread Content
What does the mixed air damper of a heating furnace mean? Do you mean the flue damper? Note: It is not the primary air damper and the secondary air damper
1. The mixed air damper is not a flue baffle. 2. The flue dampers of the heating furnace; such heating furnaces are generally bottom-fired furnaces. These flue dampers are used primarily to regulate the negative pressure in the furnace chamber, which enables the fire inside the furnace to burn more fully and can also indirectly increase the furnace temperature. As for the oxygen content inside the heating furnace, it is mainly regulated by the opening degree of the air valves in the flue. When the oxygen level is low, it indicates that the combustion in the furnace is not proper; in such cases, the air valves need to be opened wider, and then the flame intensity can be adjusted further using the flue dampers. Additionally, changes in climate have an impact on both the oxygen content and the negative pressure inside the heating furnace
I haven’t heard of anything called a mixed air damper.
Mm-hmm, yeah. I really hadn’t heard of it before; it was only yesterday that someone asked about it, and I couldn’t find any information online either
Someone asked what a mixed air damper is, and another person said it was on the upper part of the heating furnace. I went up there to take a look, and aside from the flue dampers, there wasn’t much else there
