摘要： In a device for baking of clinker, heat generated in a furnace can be used in a particularly efficient and versatile manner if the heat generated in the furnace is transferred, by means of at least one first heat exchanger, to a heat carrier fluid, the heated heat carrier fluid is transported to at least one second heat exchanger, and the heat is then discharged to a heat sink, for example, in order to heat a flow of flue gas to a temperature required for denitrification thereof.

摘要： Apparatus for the production of carbon dioxide from limestone includes a nuclear energy source (32) arranged to generate electricity and a rotary kiln (10). The rotary kiln (10) has an inlet (15) for the introduction of limestone and an outlet (19) for the release of carbon dioxide. An electrical resistance heating element (21) disposed within the kiln (10) is arranged to be supplied with electricity derived from the nuclear energy source (32) to raise the temperature of the element (21) for transfer of heat to the interior of the rotary kiln (10). Limestone in the rotary kiln (10) is thereby heated to a temperature sufficient for the release of carbon dioxide.

摘要： Denitrifying bypass exhaust gases in a cement clinker producing plant. The plant comprises a rotary kiln connected to a calciner for the deacidification of raw material or to a rotary kiln riser shaft via a rotary kiln inlet chamber, and the bypass exhaust gas being drawn off in the region of the rotary kiln inlet chamber. The method comprises: cooling the bypass gas to between 260 C and 400 C in a cooling device, injecting an ammonia-, urea-, and/or ammonium-containing substance into the cooled bypass gas, introducing the cooled and mixed bypass gas into a ceramic filter system to filter out any halide and sulfate of the alkali metals and alkaline-earth metals precipitated during cooling the gas, and any nitrogen not reacted by the injected substances is chemically selectively reduced over a catalytic converter which is located in or directly downstream of the ceramic filter system.

摘要： The present invention makes it possible to prevent the spontaneous combustion of coal while causing oxygen to be adsorbed to the surface of the coal in an efficient manner. A coal deactivation processing device includes: a rotary kiln body provided rotatably into which coal and a processing gas are supplied; a feed pipe provided so as to be able to rotate along with the rotary kiln body), extending along a lengthwise direction of the rotary kiln body (103), and having a coolant flowing therein, and a protruding portion provided to the outer circumferential section of the feed pipe so as to protrude toward the rotation direction of the feed pipe. The feed pipe and the protruding portion are arranged so as to pass through a coal layer resulting from the accumulation of coal within the rotary kiln body when the rotary kiln body rotates.

摘要： Improved methods and systems for purifying exhaust gases using regenerative post-combustion systems help reduce operating problems and increase service life of such regenerative post-combustion systems. One such method may involve preheating an exhaust gas to be purified before feeding the exhaust gas into a regenerative post-combustion system. The exhaust gas may be preheated in at least one preheating stage to temperatures between 100° C. and 250° C., for instance, preferably between 100° C. and 200° C., and most preferably between 120° C. and 150° C. Moreover, one regenerative post-combustion system may include a preheating stage, two heat stores, and an oxidation zone disposed between the heat stores for oxidizing harmful constituents present in the exhaust gas.

摘要： A plant for producing cement, having a first stage for crushing raw material to form raw powder, a second stage for calcination and sintering of the raw powder to form cement clinker, a third stage for cooling the sintered cement clinker, and a fourth stage for crushing the sintered cement clinker to form cement. The first stage for crushing raw material to form raw powder and the fourth stage for crushing the sintered cement clinker to form cement are structurally combined. In this way, during servicing or repair of one crushing stage, the plant need not be shut down because, y variable circuitry switching, the crushing stages permit plant operation with reduced production output.
