An inner liner for a tubular casing, with the casing having a support means for coaxially supporting the liner within the casing. The liner has an axis and is made of material having a different coefficient of linear expansion than the casing, and comprises at least one tubular section having an outer surface which defines at least one conical support section for resting against the support means at contact points with the support means. The contact points are located on generatrices of a conceived cone or pyramid, with the generatrices radiating from a fixed point on the axis of the liner coinciding with the tip of the cone or pyramid.

Lining

The invention relates to a pressure-relief device in a PFBC power plant with a combustor (12) enclosed in a pressure vessel (10). The device is intended to limit the pressure difference between the combustor (12) and the surrounding space (22) in the pressure vessel (10) and to initiate pressure relief of the pressure vessel (10) out into the atmosphere. Via a conduit (54) with a rupture disc (56), the combustor (12) communicates with one or more blow-off valves (42). If the rupture disc (56) bursts, a sensor (62) indicates this and effects opening of the blow-off valve (42) via signal processing and operating equipment (64). Between the rupture disc (56) and the combustor (12) a perforated diaphragm (60) is provided. In the space between this diaphragm and the rupture disc (56) a layer of particulate, heat-insulating material (58) is provided, which restricts the heating of the rupture disc (56).

Pressure relief device

A gas turbine plant having a combustion chamber (1) separate from the turbine (15) includes a conduit (16) with an inner tube (17), which conducts heated propellant gas from the combustion chamber (1) to the turbine (15); and an outer tube (18), which surrounds the inner tube (17) to form an annular gap (20) which conducts compressed air from a compressor (10) to the combustion chamber (1). (FIG. 1.)
