Question 1: How is the negative pressure in a naturally ventilated negative-pressure furnace created (without exhaust fans and supply fans)? Question 2: When a negative-pressure furnace with natural air intake is in operation, with a negative pressure of -100 Pa inside the furnace, is the air intake volume the same when the air damper is fully open and when it is partially open? (If the air damper is half open, the air intake volume is sufficient.) Question 3: In a furnace that relies on natural air intake (without an exhaust fan), is the air intake volume automatically adjusted according to the amount of fuel used?
1. The negative pressure is regulated by the opening degree of the chimney baffle at the top of the furnace. 2. Of course, the air intake volume differs when the air vents at the bottom of the furnace are fully open or partially open, and this can be reflected in the oxygen content level in the furnace chamber. 3. Generally, there is no automatic proportioning. This can only be achieved if automatic control instruments are installed.

Impressive, I agree with you; thumbs up.
1. Negative pressure and the “natural wind” used in agriculture work on the same principle when it comes to cooking hot pot! It’s all caused by the pressure difference between the exhaust and intake ports of the chimney! 2. It’s the same principle as using natural wind to cook hot pot in rural areas – the air intake volume is different when the vents are fully open versus partially open! The difference is that natural wind sometimes enters from the bottom of the pot~
Thank you, the explanation was really excellent!
