Abstract: Lime mud from kraft pulp recovery operations is processed using dielectric hysteresis heating, in a two-stage operation, in which wet lime mud first is dried then the dried lime mud is decomposed to lime and carbon dioxide. A two-zone lime mud calciner is employed in which the lime mud is conveyed horizontally, with drying being effected in the first zone and then decomposition being effected in the second zone. A co-current flow of purge air removes steam generated in the first zone and a counter-current flow of purge air removes carbon dioxide generated in the second zone.
Abstract translation: 使用介电滞后加热处理来自牛皮纸浆回收操作的石灰泥，在两阶段操作中，其中首先将湿石灰泥干燥，然后将干燥的石灰泥分解成石灰和二氧化碳。 使用双层石灰泥煅烧炉，其中灰泥被水平输送，干燥在第一区域进行，然后在第二区域进行分解。 净化空气的并流流动除去在第一区域产生的蒸汽，并且净流空气的逆流流除去在第二区域中产生的二氧化碳。

Abstract: A two-zone lime mud calciner is provided for processing lime mud from kraft pulp recovery operations. A conveyer is employed for conveying lime mud horizontally through the calciner. The first zone and second zone of the calciner each contains a dielectric hysteresis heating device for first drying the lime mud in the first zone and then decomposing the dried lime mud to lime and carbon dioxide. A co-current flow of purge air removes steam generated in the first zone and a counter-current flow of purge air removes carbon dioxide generated in the second zone with a vent being provided adjacent the upstream and of the second zone.

Abstract: A nozzle suitable for use with a device for removal of deposits from contaminated surfaces, such as a sootblower in a heat recovery boiler, is designed to avoid normal shock wave formation, and hence energy dissipation, by achieving a condition whereby, the emergent steam pressure (p.sub.e) is related to the ambient pressure (p.sub..infin.) by the relationship p.sub.e /p.sub.28

Abstract: A deposit measuring device, useful for improving combustion processes especially kraft mill recovery boilers, determines the temperature at the windward and leeward sides of a probe tube positioned in the flue gas stream transverse thereto and then determines the rate of build-up of deposits on at least the windward side and the temperature of the flue gas stream. This information is used by an operator or automatically to control boiler operations. The measuring device has a deposit removal means associated therewith periodically to remove deposits from the tube. The ability to control the boiler operation enables considerable economic benefits to be achieved.

Abstract: Deinking by-product from wastepaper recycling operations and pulp mill clarifier sludge are incorporated into drywall or other gypsum-based building products, such as building blocks. The deinking by-product or pulp mill clarifier sludge is diluted and mixed with stucco (calcium sulfate hemihydrate). The resulting slurry preferably is subjected to an initial dewatering, following the on-set of hardening of the gypsum, and drywall or other building product is formed from the dewatered material. A significant loading of fibrous material in the drywall sheet or other gypsum product is achieved using the procedure, imparting improved flexural strength to the product. The preferred procedure also may be used to incorporate virgin or recycled wood pulp into the building product.
