ABSTRACT:
A depressurization apparatus which utilizes a plurality of rupturable discs connected to lines that communicate with a conduit conveying hot gas from a pressurized fluid bed reactor to a turbine. Whenever depressurization is required due to excessive pressure in the conduit or for another reason, one or more rupturable discs are electrically fired to vent the gas to atmosphere. A separate isolation valve is provided for each disc, and can be closed to facilitate the replacement of a ruptured disc without having to shutdown the reactor.
