Abstract: The black liquor (10) from a kraft pulping process is gasified in a fluidized bed reactor (12) in the presence of solid calcium compounds (CaO, CaCO3, Ca(OH)2) which react with the sulfur compounds (H2S, COS) to produce solid CaS. The solid CaS along with the other primary solids (Na2CO3, Na2S) are removed (18) from the reactor (12) and processed to form one or more white liquor streams for recycle to the pulping process. In this processing, the Na2CO3 and Na2S are dissolved (72) to form green liquor and the CaS is reacted (78) with NaOH to form NaHS. The causticizing of the green liquor may be separate from or combined with the conversion of the CaS in the green liquor to form a single white liquor stream (104) or the CaS may be separated from the green liquor and processed entirely separately to form a second high sulfide white liquor stream (174).

Abstract: The disclosure relates to a process for the removal of solid CaS (64) from a gas stream in which the CaS has been formed and then the conversion of that solid CaS (64) by reaction with an aqueous NaOH solution (68) to produce solid Ca(OH)2 (69) and a liquor stream containing dissolved NaHS (72). This removal and conversion process is described as being used in conjunction with a process for gasifying black liquor from a kraft pulping process in which H2S is scrubbed from the gases with little or no absorption of CO2 using calcium compounds to form the CaS.

Abstract: A method for enhancing the minimization of NOx control in a circulating fluid bed steam generator (12) into which there is injected fuel, fluidizing air, a lower level of combustion air and an upper level of combustion air. The fuel is injected at a first location (30), the fluidizing air is injected at a second location (24), the lower level of combustion air is injected at a third location (50b) and the upper level of combustion air is injected at a fourth location (50a). In order to enhance the minimization of NOx control within a circulating fluid bed steam generator (12) the lower level combustion air (50b) as well as the upper level combustion air (50a) are each biased in the horizontal plane as well as the vertical plane so as to thereby control the lower level combustion air flow (50b) and the upper level combustion air flow (50a) such that local stoichiometries within the circulating fluid bed steam generator (12) are maintained within a range of 70 % stoichiometry to 90 % stoichiometry.

Abstract: A multi-tube probe apparatus (55) comprises a plurality of probe heads (60) connected to a respective plurality of flexible shaft assemblies (52) for respectively testing a plurality of tubes. A single longitudinal drive unit (55) is connected to all of the flexible shaft assemblies (52) to simultaneously move the probe heads (60) into and out of tubes. A separate rotational drive unit is connected to each flexible shaft assembly for rotating the probe head within the tube. The flexible shaft assembly comprises an outer flexible hose and an inner interlocked metal hose. The interlocked metal hose transfers the rotational force from the rotational drive unit (50) to the probe head and also contains electrical conductors within a hollow core of the hose. The interlocked metal hose is preferably used as a ground conductor so as to reduce the number of cables that are passed through the interlocked metal hose and to provide electrical shielding. A sheet pattern plate (74) positions the probe heads (60) and flexible shaft (52) assemblies to coincide with the positioning of the tubes. The single longitudinal drive unit enables the simultaneous use of more than one probe head which substantially reduces the testing time and therefore increases productivity.

Abstract: A hexagonal grid is comprised of castled strips which are (a) bent into a zigzag form, and (b) interleaved with one another so that half-height bridge segments, which extend between and are integral with adjacent full-height castle segments, are placed in edge-to-edge contact so that they align with one another. This forms a grid with no double thickness portions. During fabrication the strips are sandwiched between slotted top and bottom plates. These plates are formed with access openings at sites where three segments intersect and through which welding is carried out. Relatively long spring features are only formed in full-height castle segments. The absence of these features in the half-height bridge segments allows the overall height of the grid to be minimized.

Abstract: A grid strip (10) for a fuel rod support grid of a nuclear fuel assembly is cold-formed from a flat annealed plate having length, height, and width dimensions. A plurality of slots (12, 14) extend along the height dimension at regular intervals along the length dimension, thereby defining successive cell walls (16, 18, 20) between successive slots along the length dimension. Each cell wall has upper, central and lower regions (28, 30, 32) along the height dimension, each region including a substantially flat base area (34, 36, 38) and fuel rod support structure (22, 24, 26) projecting integrally from the base area along the width dimension of the strip. The support structure in each of the upper and lower regions includes a relatively stiff, arched stop (22, 26) which projects in a first direction and the support structure in the central region includes a relatively soft, arched spring (24) which projects in a second direction opposite the first direction. The spring includes spaced apart pedestals (40, 42) formed in the base area of the central region and projecting in the second direction, and a resilient beam (44) extending between and rigidly supported by the pedestals, so as to project in the second direction beyond the projection of the pedestals.
