Barometric Damper Anyone? Jan 5, 2017 19:31:31 GMT -8 via mobile

Does anyone use a barometric damper on their exhaust flue exiting the bell of a batch rocket? When the wind blows and draft spikes the fire rockets harder. Is that a good thing or bad thing in a bell system? Would it be better to have a barometric damper regulate the draft so it never spikes above a certain level?

My chimney draft frequently spikes to between .05 -.09 inches water column as measured by my magnahelic manometer.
