How to adjust the negative pressure in the furnace chamber of a tubular heating furnace
Thread Content
The heating furnace in our facility is a tubular type, equipped with a blower (but no exhaust fan). In windy weather, the negative pressure inside the furnace chamber fluctuates significantly, and adjusting the flue dampers does not help. We would like to ask those who use similar types of heating furnaces how they address this issue. Thank you!
To address the issue of fluctuations in negative pressure inside the furnace of tubular heating furnaces, it is possible to try installing a frequency converter to control the speed of the blower, or to add bypass pipelines and control valves between the furnace inlet and the chimney in order to regulate air flow and thus stabilize the pressure inside the furnace. If the above measures still do not resolve the issue, it is recommended to consult a professional furnace design and maintenance team for on-site diagnosis and adjustments. .
