Smoke exhaust fan after energy storage accident

What happens if a smoke exhaust system fails?

Failure to create this equilibrium con-dition, e.g., due to absent or inade-quately dimensioned smoke exhaust systems, will result in smoke sprea-ding initially through the fire room and then through the building.

What is a smoke exhaust fan?

Thus, the ‘‘smoke exhaust fan’’ was born, although a market warranting volume production or even promising significant sales revenue had yet to be identified. At the time, stationary smoke exhaust fans were virtually un-known as a preventive fire protection solution.

Should smoke exhaust fans be installed outside a fire room?

As soon as the temperature in the fire room rises beyond the equipment’s withstand li-mits, the operability of the smoke ex-haust system is jeopardized. The ba-sic rule, therefore, is that fans should always be installed outside the fire room unless they have been ex-pressly designed and certified for such installation.

What is a powered smoke exhaust?

Powered smoke exhausts are indi-vidual components of a smoke and heat exhaust installation designed to extract smoke from a building. Contrary to gravity-based systems, powered smoke exhausts rely on forced ventilation (induced, e.g., by special-purpose fan).

What kind of fans do smoke & heat exhaust Sy-stems use?

Powered smoke and heat exhaust sy-stems rely on the use of centrifugal and axial-flow fans of appropriately adapted design. The manufacturing industry can today supply fans for this particular application with volume flo-ws up to about 300,000 m3/h. and temperature ratings up to 1,000°C.

What is a smoke and heat exhaust system?

Smoke and heat exhaust systems are designed to extract smoke and its heat loads to an outdoor location so as to reduce the hazards outlined above. Depending on specific building condi-tions, this objective can be achieved either through natural (gravity) venti-lation or by mechanical (fan-powe-red) equipment.
