The Arrangement and Selection of Ventilator£º

The diameter of the ventilator should be greater than 200mm, and the wall thickness should be no less than 3mm. The ventilator can be fixed type or movable type. The hood should be arranged as far as possible away from the exhaust pipe, skylight, chimney and boiler bulkhead, so as not to absorb dirty and hot air.

Windbreakers on open freeboard decks shall be provided with storm covers, and windbreakers on other decks shall also be provided with rain canvas covers.
