FIRE EXTINGUISHING SYSTEM FOR AN ORGANIC RANKINE CYCLE HYDROCARBON EVAPORATOR

摘要

PROBLEM TO BE SOLVED: To provide an organic Rankine cycle energy recovery system including features which provide for fire suppression and/or ignition suppression in the event of an unintentional release of a flammable component of the system, for example a flammable working fluid such as cyclopentane, into a part of the of the system in which the prevailing temperature is higher than the autoignition temperature of the flammable component.

SOLUTION: The organic Rankine cycle energy recovery system 10 includes an inert gas source 34 disposed upstream of a hydrocarbon evaporator and configured to purge the contents of the hydrocarbon evaporator with an inert gas on detection of a leak thereby.
