Abstract: The invention relates to a method for making the drying of materials, particularly finely divided materials, more effective, in which method, of a slurry containing liquid and solids there is made a filter cake (2,12,22) onto the surface of the filter medium (1,11,21). According to the invention, the filter cake (2,12,22) and the oscillator (6,15,25) are arranged, in relation to each other, so that in between the filter cake (2,12,22) and the oscillator (6,15,25), there is generated an acoustic field by virtue of a mechanical contact between the filter cake (2,12,22) and the oscillator (6,15,25) or a structural element (7,16,26) connected to the oscillator.

Abstract: The invention describes a device for through-flow continuous processing of textiles, nonwovens, or paper in web form with a gaseous processing medium circulated in the device. The material rests on the outside of a permeable drum subjected to suction, said drum having bottoms on the ends, namely a sieve-type or perforated covering that rests on the drum structure. For this purpose, sheet metal strips firmly connected with the bottoms extend from one bottom to the other between the bottoms of the drum, with the widths of the strips extending in the radial direction. These sheet metal strips are secured over their entire radially aligned height firmly but releasably to the corresponding bottoms by means of the clamping structure.

Abstract: A screen drum design is known whose drum jacket consists of sheet metal strips running axially and whose width extends in the radial direction. These sheet metal strips must be permanently connected with the endwise bottoms to produce the drum jacket. According to the invention, this connection is made movable. For this purpose, an articulated ring (32) is used that consists of a number of connecting arms (13) mounted pivotably, said arms being connected with articulation at their free ends either with sheet metal strip structure (13, 14) or with bottoms (11, 12) that are located at a distance from the ends of sheet metal strips (13). In this way, movement is always possible between the drum jacket and bottoms (11, 12) to compensate for dimensional changes as a result of temperature fluctuations.

Abstract: The known method of burning solid fuel by means of a fluidized bed is improved so as to reduce the amount of generated NO.sub.x and to enhance the efficiency of combustion. Primary air, secondary air and tertiary air are respectively fed through a primary air feed port opening at the fluidized bed, through a secondary air feed port opening at a free board downstream of the fluidized bed and through a tertiary air feed port opening downstream of the secondary air feed port. The feed rates of the primary air, secondary air and tertiary air are respectively controlled so that the air ratios with respect to the theoretical amount of air after charging of the primary air, after charging of the secondary air and after charging of the tertiary air may become about 0.6-0.8, about 0.8-1.0 and about 1.0 or higher, respectively. Preferably, unburnt ash sputtered from the fluidized bed is recirculated into the fluidized bed.

Abstract: A known reheat type exhaust gas boiler of the type having superheaters and reheaters disposed in parallel in the most upstream portion of an exhaust gas boiler main body, is improved by simplifying the structure and providing more effective recovery of heat from the exhaust gas. The superheaters and reheaters are divided into a plurality of stages. A high-temperature side superheater and a high-temperature side reheater are disposed in parallel in the most upstream portion of the gas flow. A low-temperature side reheater is disposed on the downstream side of the high-temperature side superheater, while a low-temperature side superheater is disposed on the downstream side of the high-temperature side reheater.

Abstract: A steam generator upper support arrangement provides restraint to the steam generator during operating and non-operating conditions, for loading forces resulting from seismic and postulated accident conditions, while allowing for free thermal expansion of the steam generator in the radial, lateral, and vertical directions. Four embodiments of the present invention are described. In a first embodiment, inclined bumpers are placed at predetermined angles with respect to the load path, such that as the steam generator is thermally displaced the placement and incline angles of the bumpers will compensate for the expansion and maintain a nominal gap therebetween. In a second embodiment, the variable shim mechanism comprised of cams, bumper rods, and a pivoted linkage between the steam generator and the building structure maintains the nominal gap for the required support. In the third embodiment, a single small snubber is utilized.
