Abstract: A gas collection pipe (1) carrying hot gas establishes the connection between the combustion chambers (9) of a gas turbine plant and the flow channel (13) of the gas turbine. The gas collection pipe (1) has two inlet pipe connections (2), which open via an elbow (3) axially into a gas ring channel (4), which is joined to the flow channel (13). Cooling air is guided on the outside along the elbow (3). A plurality of ribs (8) are arranged at spaced locations from one another on the outside on the gas collection pipe (1) in the area of the elbow (3) on the side facing away from the flow channel (13).

Abstract: A combination power plant is provided with a gas turbine (1) with generator (28) and with steam generators (2, 10) for a steam turbine (6) with generator (29), wherein the exhaust gas of the gas turbine (1) is fed to a first waste heat boiler (2) with superheaters (23, 24), economizer (3), HP evaporator (22) and auxiliary burner (27), and flue gases of a thermal conversion unit are fed to a second waste heat boiler (10). A high-pressure (HP) evaporator (16) with a supporting tube system (13) and HP steam collecting drum (11), on the one hand, and a low-pressure (LP) evaporator (17) with a supporting tube system (14) and LP steam collecting drum (12), on the other hand, are arranged in the second waste heat boiler (10), through which flue gases flow. The P evaporator (16) is connected via a steam line (21) to the first (23) and second HP steam superheaters (24) arranged in the first waste heat boiler (2).

Abstract: Tenter driers are frequently used for drying textile webs whose edges have an increased weight per unit area or have been treated with glue. It is extremely difficult to dry the edges to the same degree of residual humidity as the remainder of the web. In the inlet region, the blower box has been replaced by blower pipes extending parallel to the chain rails. The pipes are connected to the recirculated air system of the drier and provided with nozzle apertures directed towards the web edges. Since only a low drying capacity is available, the drier either has to be extended or the throughput speed has to be decreased. With the drier according to the invention, a longitudinal section which starts at the inlet and extends over at least 20% of the total length is equipped with blower pipes (27, 28) aligned parallel to the chain rails (13, 14). Blower boxes (18, 19) are also mounted in this longitudinal section, both above and below the textile web (15).
