Abstract: An annular-gap seal for a valve, blocks the fluid flow from a high-pressure side to a low-pressure side. The valve has a cylinder, through which the fluid flows and in which a piston is axially displaced. In the blocked position, an annular gap between the piston and the cylinder can be sealed by the annular gap seal, which lies in a groove that runs around the cylinder. To increase the sealing action of the gap seal, two sealing rings lie adjacent to one another mirror-symmetrically in the groove. In the blocked position, fluid from the high-pressure side causes a sealing lip of a first sealing ring that faces the low-pressure side to be pressed in a fluid-tight manner against the piston and a sealing face of the first sealing ring to be pressed in a fluid-tight manner against the wall of the groove.

Abstract: A method produces a product gas rich in hydrogen. A starting material including carbon is split via pyrolysis, and the resulting gas is mixed with water vapor to increase the hydrogen content and heated. The heat necessary comes from the combustion of the produced pyrolysis coke. The heat necessary for individual process steps is fed via a heat transfer medium circuit having a heating zone heated via flue gas from the pyrolysis coke firing. The gas/water vapor mixture is subsequently heated in a reaction zone. The heat transfer medium heats the starting material in a pyrolysis zone indirectly, without directly contacting the starting material, is cooled in a cooling zone, and subsequently returns to the beginning of the circuit. Upstream of the heating zone, the heat transfer medium is preheated via the hot product gas.

Abstract: A material-sparing, reusable stack holding system for supporting and transporting framed photovoltaic or solar thermal flat modules. The system consists of individual molded parts, which form stable and transport-safe pillars or rails, respectively, among one another by means of mechanical cogging and with the frames of the modules by means of a locking connection. To date, only stack holders, in the case of which the solar modules are stacked in horizontal position with the use side facing up (“sunny side”), were known. The system disclosed here makes it possible to stack the modules in horizontal as well as in vertical position. In the case of horizontal stacking, the use side can be arranged facing up or down.
