摘要： A recovery boiler for combusting spent liquor from cellulose cooking while at the same time recovering chemicals. The recovery boiler is constructed for so-called "rotafire" combustion and the speed of rotation of the secondary air has been increased by a constriction of the boiler being arranged at the tertiary air level. The invention also includes a process for using the boiler which is based on certain ports through which the secondary air is blown in being provided with air which is at a higher pressure than that at the other ports on the same level, thereby achieving a higher inflow velocity than from the other ports.

摘要： A combustion plant includes a circulating fluid bed, which is maintained by the supply of fuel, inert material and oxygen-containing fluidizing gas to a vertical furnace shaft. This is, at its upper end provided with an outlet for combustion gases and bed materials, which is separated from gas in a separating means, and by way of a lock is returned to the furnace shaft. The separating means is of a mechanical type, and located vertically above a further vertical shaft communicating with the lock. The further shaft encloses distribution means for the particles and a heat exchanger for cooling the particles falling from the gas stream, before they are re-introduced into the furnace shaft by way of the lock.

摘要： The method and equipment are for the evaporation of hot black liquor obtained from a digestion process during the production of cellulose pulp. The black liquor is led to a multistage evaporation line with at least five evaporation stages. The black liquor that is to undergo evaporation in the evaporation line is cooled in at least one heat exchange process in a heat exchanger (HE1) against the partially evaporated black liquor that has undergone evaporation in at least one stage (I). The black liquor that is to undergo evaporation is cooled and the partially evaporated black liquor is heated by at least 5-10° C. The risk for the formation of foam and the separation of methanol are reduced. The greater part of the evaporation takes place at low temperature and at the lowest level of dry matter content in the liquor, which also suppresses encrustation in the stage.

摘要： The invention relates to a method of firing black liquor in recovery boilers where the intention is to obtain fumes having a low content of nitrogen oxides (NO.sub.x). A part of the combustion air is added as a last portion at a very high level so that a reducing atmosphere will exist in a very great part of the boiler for a long time period, e.g. at least 3-5 seconds.

摘要： The strainer arrangement is adapted for straining a liquid from a mixing arrangement, such as a mixing tank, containing black liquor including solid particles of ash. The strainer arrangement comprises a strainer pipe with axial gaps defined therein for permitting a radial inflow of liquid into the strainer pipe. An axially movable shaft is disposed inside the strainer pipe and has cleaning pins attached thereto that extend into the gaps.

摘要： An evaporation apparatus for evaporation of, for example, spent liquor from pulp cooking. The apparatus has a vertical cylinder that has evaporation surfaces disposed therein. An outlet opening is defined in a widened part of the cylinder to receive driven-off steam. A skirt is disposed in the cylinder and surrounds the evaporated liquid and driven-off steam and has a diameter that is smaller than a diameter of the widened part. The skirt has an open bottom and a skirt opening is defined in a portion of the skirt that is facing away from the outlet opening.

摘要： The process for the final evaporation has at least two evaporation appliances. These appliances are coupled in series with respect to the black liquor and in parallel with the live steam (primary steam), which drives the evaporation, and with the secondary steam that is generated by the evaporation. The pressure of the primary steam that is supplied to the appliance(s) where the liquor concentration is at the highest concentration is greater than the pressure of the primary steam supplied to the other appliances where the liquor concentration is not so high.
