摘要： The invention relates to a method for using the waste heat from a plant for producing cement, wherein heat of a process gas is used through a heat exchanger (21) to heat water vapour, and wherein the plant for producing cement has at least one calcinator (2, 4) and at least one heat exchanger (1), which consists of a sequence of cyclones (1a, 1b), for heating raw mix. The invention also relates to a plant for producing cement, wherein the plant for producing cement has at least one calcinator (2, 4) and at least one heat exchanger (1), which consists of a sequence of cyclones (1a, 1b), for heating raw mix. According to the invention, the process gas is taken at the outlet (10) of the calcinator (4) and/or at the gas-side outlet (11) of the first cyclone (1b) in the heat exchanger (1) in the direction of gas flow and, once the heat has been depleted in a steam vessel (21), the cooled process gas is fed back into the second cyclone (1a) or third cyclone in the heat exchanger (1) in the direction of gas flow. This has the advantage that the heat taken from the process can be used for the further heating of unrecovered heat which can thereby be more efficiently converted into electrical energy.

摘要： The invention relates to a method for the denitrification of bypass exhaust gases (105, 205, 305) in a plant for producing cement clinker, the plant comprising in the gas flow direction a rotary kiln (102, 202, 302), and said rotary kiln (102, 202, 302) being connected to a calcinator (107, 207, 307) for the deacidification of raw meal or to a rotary kiln riser shaft via a rotary kiln inlet chamber (104, 204, 304), and the bypass exhaust gas being drawn off in the region of the rotary kiln inlet chamber (104, 204, 304). The method according to the invention comprises the following steps: cooling the bypass gas (105, 205, 305) to a temperature between 260°C and 400°C in a cooling device, injecting an ammonia-, urea- and/or ammonium-containing substance into the cooled bypass gas (112, 21, 312), introducing the bypass gas (112, 21, 312) that has been mixed with an ammonia-, urea- and/or ammonium-containing substance and cooled into a ceramic filter system (114, 214, 314), in which any halide and sulfate of the alkali metals and alkaline-earth metals precipitated during cooling of the bypass gas (112, 21, 312) is filtered out, and any nitrogen oxide not yet reacted by the ammonia-, urea- and/or ammonium-containing (NH
4
+ ) substance is chemically selectively reduced over a catalytic converter (116, 216, 316) which is located in the ceramic filter system (114) and/or which is located directly downstream of the ceramic filter system (214, 316).

摘要： The invention relates to a method for treating biomass fuel in a plant for producing cement clinker, wherein the biomass is first subjected to initial drying by the gases given off by a heat exchanger in the plant, and to a corresponding plant for producing cement. The proposal according to the invention is that biomass be carbonized before being used, utilizing the heat given off by a heat exchanger present in the plant, as a result of which the low-calorific-value heat given off can be utilized to process the biomass for an energetically advantageous fuel.

摘要： The invention relates to a plant (1) for producing cement clinker, comprising as viewed in the direction of materials flow at least one heat exchanger (1.1) to preheat raw meal (2), at least one downstream calciner (3) to calcine the raw meal (2), at least one rotary kiln (8) to sinter the calcined raw meal (2), and at least one clinker cooler (11) to cool the sintered cement clinker; a firing means carbonizes, pyrolyses or burns difficult fuels - those which have unpredictable ignition characteristics, usually ignite poorly, or require assisted ignition in the form of substantial heating plus initial pyrolysis. In accordance with the invention, the firing means is embodied as a pot reactor or gooseneck reactor (5) in inverted U-shape, which is positioned upstream of the calciner (3) on the flow path of the exhaust gases from the rotary kiln (8) to the calciner (3) and which has a gas outlet (5.1) that opens out above a tertiary-air line (4.1) of the clinker cooler (11) into the calciner (3). As a result, it becomes possible to burn fuel which is lumpy and/or has poor ignitability, and the gases from incomplete combustion in the reactor are available in the calciner in gaseous form for further combustion.
