Multi-flue Chimneys: an Investigation into the Durability of Flue Linings

The Clean Air Act of 1956 stipulates minimum heights for industrial chimneys according to the size of the boiler plant and also requires higher flue gas exit velocities which consequently produce chimneys of smaller diameter. On a multi-boiler plant the multi-flue chimney permits the maximum flue gas velocity to be achieved at all boiler loadings since each boiler has its own flue, however the beneficial aspects of the small diameter flue can be offset by the practical construction difficulties of freestanding brick linings of small diameter.
