摘要： A method for generating steam in a digester plant of a chemical pulp mill including: producing black liquor in the digester plant, extracting a first stream of black liquor from the digester; generating vapor by evaporating the first stream of black liquor by heating the first stream with fresh steam; heating fibrous material in the digester with the generated vapor from the evaporated first stream of black liquor; extracting a second stream of black liquor from the digester; flashing the second stream of black liquor to generate flashed black liquor and flashed black liquor vapor; introducing the flashed black liquor vapor to at least one heat exchanger to indirectly heat a clean evaporable liquid to produce clean steam from the clean evaporable liquid; and steaming, with the clean steam produced in the at least one heat ex-changer, cellulosic feed material before feeding the cellulosic feed material to the digester plant.

摘要： In a boiler, a space is reserved to expand the boiler by increasing the front and rear walls. To expand the boiler, wall additions are added to increase the width of the front and rear walls. After the expansion, the distance between the front and rear walls is substantially the same distance between the front and rear walls before the expansion.

摘要： The present invention relates to a method and an arrangement for use in connection with the combustion of black liquor. In the method the black liquor is concentrated in a multi-effect evaporation plant in order to obtain black liquor at a suitable dry-solids content for combustion and to generate vapor. The concentrated black liquor is taken to be combusted in a recovery boiler, into which combustion air is fed at several levels for the combustion process. It is a characteristic feature of the invention that the air fed to at least one air level is preheated by using vapor generated in the concentration of the black liquor as heat source.
摘要翻译：本发明涉及一种与黑液燃烧有关的方法和装置。在该方法中，将黑液浓缩在多效蒸发装置中，以获得用于燃烧的合适的干固体含量的黑液并产生蒸气。浓缩的黑液被采集在回收锅炉中燃烧，燃烧空气以几个等级供入燃烧过程。本发明的一个特征是，通过使用以黑液浓度产生的蒸气作为热源，将进料到至少一个空气水平的空气预热。
