Abstract: A device for the calorimetric determination of the decay heat power of fuel elements has a calorimeter container with a coolant inlet and a coolant outlet, a line system with a coolant removal line and a coolant supply line, a feed pump, a flow measuring device, a first temperature measuring device at the coolant inlet, a second temperature measuring device at the coolant outlet, and a closing cover.

Abstract: A valve block for a piggable and/or solid-state conducting line system of a process technical plant can include one or more rotary control valves. The rotary control valve(s) can include one or more line inputs, one or more line outputs, and a rotatable control member with one or more through-channels. In an open position, a line input of the one or more line inputs is connected to a line output of the one or more line outputs through a through-channel of the one or more through-channels. In a closed position, the first control member separates the one or more line inputs from the one or more line outputs. The rotary control valves are rotatable about a same rotation axis and the control members are non-rotatably connected to each other. The one or more through-channels of respective rotary control valves are offset plane-parallel relative to each other in an axial direction of the rotation axis.

Abstract: A system and a method for promoting improved air flow through a cooling tower and reduced inner air pressure losses caused by rain in the rain zone of a cooling tower. Aerodynamic modules are mounted on the lower edge of the cooling tower shell in order to deflect the downward-flowing air about the lower edge of the tower shell and into the rain zone. The aerodynamic modules can be modularly mounted, can be replaced, and do not affect the statics of the tower shell. Aerodynamic modules can also be built on the base area to deflect the incoming air over any obstacles. Troughs or dripping elements can also promote flow by reducing the rain falling in an outer area.
