Abstract: A description is given of a burner for introducing solid, liquid or gaseous fuel to a burning zone of a kiln, such as a rotary kiln for manufacturing cement clinker or the like, said burner comprising a number of substantially concentric ducts (1, 2, 3), being parallel to the main axis B3 of the burner, for conveying fuel and primary air to nozzle openings, as well as a number of additional ducts (4, 6, 7, 8) for conveying solid, fluid or gaseous fuel to separate nozzle openings, said additional ducts being located in the central part (10) of the burner. The burner is characterized in that it comprises means (4a, 5) for changing the flow direction of the fuel which is introduced via at least one of the additional ducts in the central part (10) of the burner, relative to the main axis B3 of the burner, at least in an ascending direction. This will allow the individual fuel particles to travel in a curved, approximately ballistic path, thereby extending the time they can be maintained in the flame. Another advantage of this configuration of the burner is that the large particles will attain the highest, and hence the longest, path, since the path of the smaller particles will to a greater extent than is the case for the large ones be deflected by the primary air which is injected via the outer annular primary air nozzle which is parallel to the main axis of the burner. Hence it will be possible to achieve a more uniform combustion of all particles, regardless of their size. It will be possible to change the path of the particles by altering the velocity or direction of injection.

Abstract: Described is a method as well as a plant for manufacturing cement clinker, by which method cement raw materials are preheated in a preheater (1), calcined in suspension with hot gases in a calciner (2, 20), separated from the gases in a cyclone (2a), burned into cement clinker in a kiln (3) and subsequently cooled in a cooler (4) by which method a quantity of calcined raw material with a high content of CaO is extracted via a calcination stage (2, 20) by means of an additional separation cyclone (5a). The method and the plant are peculiar in that the gases which are diverted from the additional separation cyclone (5a) are cooled to a temperature of maximum 850 °C by means of cement raw materials which are introduced into the gas stream. It is hereby obtained that the quantity of material which is extracted by means of the additional cyclone can be adjusted by means of known means in a more reliable manner than has hitherto been possible, while also significantly reducing the risk of alkali-induced clogging. This is due to the fact that the lower temperature allows utilization of generally known control means and the fact that the alkali in the gases will condense and settle on particles in the gases at temperatures which are lower than 850 °C.

Abstract: Described is a method as well as a plant for the simultaneous production of electricity and cement clinker by which method cement raw meal is calcined in a calciner (4) subject to simultaneous supply of fuel and combustion air and subsequently burned into cement clinker in a kiln (5), and where some of the heat contained in the exhaust gases from the calciner (4) is utilized to generate electricity by means of a boiler section (18). The method and plant are peculiar in that the combustion air supplied to the calciner (4) does not contain alkali or chloride, and in that the temperature of the exhaust gases used to generate electricity is at least 500° C. Hereby is obtained that coating formations formed on the boiler tubes due to the condensation of alkali and chloride vapours can be avoided, while, at the same time, the efficiency with which thermal energy can be converted into electrical energy can be increased.

Abstract: Described is a method as well as an apparatus for hydration of a particulate or pulverulent material containing CaO. The method is peculiar in that water is added in a quantity which will ensure that the partial pressure PH2O of the added water as a function of the temperature (°C) is maintained within the interval defined by the formula (I), where PH2O is the partial pressure of water vapour in atm. and T is the temperature in °C. Hereby is obtained that the material particles do not lump into agglomerates, and that the particles are hydrated evenly from the outside and inwards so that it is the active surface of the material particles which undergoes hydration in connection with partial hydration. This is due to the fact that the liquid water will not get into contact with the material particles since the water will appear in vapour form within the specified interval.
