An actuator device for mechanisms located within a pressurized environment including a double acting piston and cylinder combination operating in the same environment. The motive power for the piston is provided by pressurized gas from the pressurized environment or from a substitute source, whereby complex and elaborate sealing systems are eliminated.

Activator device for movable components

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.

Pressurized fluid bed hot gas depressurization system

A support device and structure for supporting horizontal tubes of a conventional or fluidized bed steam generator comprising a vertical tube for carrying plural pairs of support brackets. Each support bracket has a central sleeve with a pair of opposite extending tube hooks that taper in width from the sleeve, outwardly to an end of the tube hook. The ends of the tube hooks for each pair of support brackets extend toward each other, but are maintained at a distance from one another to avoid the accumulation of ash or other bed material. Welded-on nubs along the length of the support tube localize the axial position of the bracket pairs.
