A vessel for cooling syngas comprisinga syngas collection chamber and a quench chamber, wherein the syngas collection chamber has a syngas outlet which is fluidly connected with the quench chamber via a tubular diptube,wherein the diameter of the diptube at the end nearest to the syngas collection chamber is greater than the diameter of the diptube at the end terminating at the quench chamber.
摘要:
A reactor vessel includes a dipleg connecting a tubular syngas collection chamber and a quench chamber. The collection chamber connects to the dipleg via a slag tap having a frusto-conical part starting from the lower end of the collection chamber and diverging to an opening connected to an interior of the dipleg. The slag tap has a first tubular part connected to the opening of the frusto-conical part and extending in the direction of the dipleg. A second tubular part connects to the frusto-conical part or to the tubular part and extends toward the dipleg. The second tubular part is spaced away from the dipleg to provide an annular space having a discharge conduit. The discharge conduit has a discharge opening located to direct water along the inner wall of the dipleg. At least half of the vertical length of the first tubular part extends below the discharge opening.

An electroacoustic transducer has reduced loss due to acoustic waves emitted in the transverse direction. For this purpose, a transducer comprises a central excitation area, inner edge areas flanking the central excitation area, outer edge areas flanking the inner edge areas, and areas of the busbar flanking the outer edge areas. The longitudinal speed of the areas can be set so that the excitation profile of a piston mode is obtained.

摘要:
The invention relates to a transducer operating with surface waves that shows an improved frequency response of the group delay vs. the SAW-transducer familiar until now with its high flank steepness of the transfer function. The transducer is constructed on the basis of SPUDT-cells, whereby in constructing the transducer at least two cells are anticipated which are identically constructed up to their scaling. They are thereby differently scaled in longitudinal direction. According to the degree of scaling, the local phase of the acoustic wave lets itself be influenced so that the waviness in the frequency description of the group delay in the pass band of the filter, in which the transducer according to the invention is used, amounts to at most 50 ns.
摘要:
The invention relates to a tensioner (1) for a traction drive with a rotationally fixed housing (2) to a side of which a rotatable swivel arm (10), provided with a rotatable tension roller, is associated. A torsion spring (7) is placed between the housing (2) and the swivel arm (10) for loading the swivel arm (10) in the direction of an end position. Support of the tension spring (7) is realized by an insert (17a) placed in a circular ring shaped space (16) radially defined by a housing portion and the torsion spring (7).
摘要:
In connection with generating a global model of output variables of a nonlinear dynamic real system, for example, of an internal combustion engine, a drive train, or a subsystem thereof that covers the entire space of all operating points of the system, a measurement of the system is performed for a subset of variation points that are defined by a set of parameters of the system.In order to provide rapid and precise generation of the experimental designs, and the global optimization thereof, while taking into account the test constraints and additional criteria, at least two subsets selected as a function of each other are determined in succession, a common experimental design is generated taking into account the variation points of all subsets, and the system is measured based on this experimental design.
