Weather cap device removes heat from structures with sensitive exhaust systems

The invention provides a device for removing heat from a building

Darius D. Lisowksi, of the Nuclear Science and Engineering division, has patented a weather cap device for removing heat from structures such as power generating stations to protect sensitive exhaust systems from wind-induced downdrafts in chimneys. Heat egress is particularly important in solar chimney and nuclear passive safety systems to maintain mechanical integrity. The weather cap removes heat from a building by directing exhaust from a flue to a passageway which forms a slipstream along its axis. Precipitation entering the passageway is routed outside the building. The device requires no human involvement, is fully operational in all wind conditions and precipitation scenarios and can be applied to a myriad of heat removal scenarios.
