Abstract

This chimney uses the shape of its exterior housing and internal baffles to improve the draw of fireplace and stove chimneys while providing protection against precipitation and foreign objects entering the chimney. It has no moving parts, but the baffle design and exterior shape causes wind from any direction to enter at the bottom and exit from the top enhancing the chimney'"'"'s draw by creating a vinturi affect. The side baffles shape diverts precipitation from the chimney while the center baffle has a precipitation collection and diversion system. This design avoids down drafts and allows the chimney to function as intended even in high winds.
