Shut-off system for flue gas conduits or air intake conduits in oil and gas fire systems |
摘要 |
An energy-saving closure system is provided for use in preventing needless energy loss. The system employs a pivotal closure adapted to alternately move between the fully open and fully closed portion in a conduit for conveying gases relative to a combustion zone. The closure requires pressure diffentials only for being urged into the open and closed positions such as normally occur in the heating cycle. No energy-consuming, auxiliary apparatus is needed.
