摘要： In a method for reducing the NOx emissions of a rotary kiln of a clinker production plant, fuel supplied through a burner of the rotary kiln is burned along with primary air fed through the burner, wherein the primary air has a lower oxygen content and the primary air has an oxygen content reduced relative to that of the ambient air and a temperature increased relative to that of the ambient air, and the primary air is obtained by mixing ambient air with exhaust gas from the rotary kiln or from a heat exchanger connected to the rotary kiln and used for preheating raw meal. The primary air is further obtained by mixing with hot air, in particular waste air from a clinker cooler.

摘要： The invention relates to a device and a method for producing clinker from raw cement material. The raw cement material is preheated in a preheater, is precalcined in a calcining apparatus, is completely burned in a sintering furnace, and is finally cooled in a cooler. Tertiary air of the cooler is fed to the calcining apparatus while eliminated dust is thermally treated in a dust burning reactor with the aid of combustion air and fuel. At least some of the tertiary air is fed to the dust burning reactor as combustion air while the dust that is to be treated and the combustion air penetrate the dust burning reactor in the same direction of flow.

摘要： The present disclosure provides an energy-efficient (low energy consumption), carbon enriched cement production system and a method for producing cement clinker. This system involves raw material preheating and precalcining system and sequentially connected kiln inlet chamber, rotary kiln and cooler, wherein the raw material preheating and precalcining system involves precalciner and preheater, and the cooler involves first cooling zone and second cooling zone. The first cooling zone includes first cooling partition and second cooling partition, wherein a mixture of pure oxygen and high-concentration CO2 flue gas entering the inlet of the first cooling partition, high-concentration CO2 flue gas entering the inlet of the second cooling partition, and air entering the inlet of the second cooling zone have solved the problems in existing cement kiln CO2 enrichment technology, i.e., extensive air leakage and high energy consumption between the first cooling zone and the second cooling zone.

摘要： A process for producing cement clinker may involve preheating raw meal in a preheater, calcining the preheated raw meal in a calciner, burning the preheated and calcined raw meal in a furnace to give cement clinker, cooling the cement clinker in a cooler, branching off a portion of the furnace offgases flowing out of the furnace as bypass gas, cooling the bypass gas in a mixing chamber with a cooling gas, and separating out dust present in the bypass gas. The cooling gas is formed at least partly or completely from the bypass gas and/or the calciner offgas and/or the preheater offgas. The cooling gas is introduced into the mixing chamber in a ratio of 2-10:1 relative to the bypass gas.

摘要： A method for manufacturing clinker including the steps of sintering raw meal in a kiln to clinker, preheating the raw meal in a preheater using a main flue gas stream from the kiln as a heat source, dedusting the main flue gas downstream from the preheater at a temperature below the boiling point of mercury, thereby obtaining mercury-loaded dust and withdrawing a bypass flue gas stream from the kiln. Implementation of the method results in efficient removal of the mercury from the process if mercury in the bypass flue gas is evaporated by injecting at least a fraction of the mercury-loaded dust into the bypass flue gas stream. Subsequently, the bypass flue gas is dedusted and cooled down. The mercury can be adsorbed by injecting an adsorbent like activated charcoal into the bypass flue gas. With the subsequent removal of the adsorbent, mercury is finally removed from the process.
