With regards to vibration I see it as air speed inside as vibrating back and port. Why not add a length on the stack say 1 meter. Hot air will always have the tendency to go up. When its hot enough in the barrel the flue gas will tend to rise countering the downward flow. Thus at some point it becomes a tug of war between flue gas trying to go up in the drum and flue gas trying to go up the stack.

There is air heating as well from the typical RMH barrel, and a fan that moves air from the ceiling above the barrel down toward a cooler zone may be beneficial. It is important to take into account that moving air is an effective cooling mechanism, and moving air that is not sufficiently warm (above room temperature) will actually make people feel colder.
