摘要： A method for shielding the inner surface above the shield refractory (4) of the furnace wall (3) of a circulating fluidized bed boiler from erosion caused by suspension flows, in which method a shield structure is formed on the inner surface of the boiler wall. At least a first zone (1) and a second zone (2) are formed in the shield structure, the erosion-resistance properties of which zones differ from each other. In addition the invention relates to a circulating fluidized bed boiler, which comprises a corresponding shield structure.

摘要： The object of the present invention is a method in cooling medium circulation, whereby the recovery boiler comprises a furnace limited by wall tubes provided with cooling medium circulation and substantially horizontal floor tubes; a supply system for combustion air; and a supply system for black liquor, whereby a so-called smelt layer is formed in a combustion process on the floor composed of the floor tubes. At least in some of the floor tubes, at least on a section of their length, is arranged a longitudinal flow--particularly a spiral flow--for mixing the liquid and steam phases of the cooling medium.

摘要： A process for the recovery of heat and chemicals from spent liquor by evaporating water out from it in order to concentrate the liquor and be feeding the concentrated liquor thereby obtained and air into the soda-ash furnace. In order to increase the dry-matter content of the liquor to a level higher than usual, without at the same time increasing the viscositty of the liquor immoderately, at least the final concentrating (5, 9) of the liquor and its feeding (16) into the soda-ash furnace (4) are carried out under pressure at a temperature higher than the atmospheric boiling point of the liquor.
