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.

摘要： A method for manufacturing clinker includes sintering raw meal in a kiln to clinker, preheating the raw meal (prior to sintering the raw meal) in a preheater using a main flue gas stream from the kiln as heat source, dedusting the main flue gas downstream of 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. The method is configured to efficiently remove mercury from the manufacturing process if mercury in the bypass flue gas is vaporized by injecting of 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. Thereby, the mercury can be adsorbed by injecting an adsorbent (such as activated charcoal) into the bypass flue gas. With subsequent removal of the adsorbent, mercury is finally removed from the manufacturing process.

摘要： A method for cleaning bypass gases of the cement or mineral industry includes cooling down a removed bypass gas from a cement or mineral processing plant to a temperature of between 500° C. and 150° C., and coarsely dedusting the bypass gas, the dust burden being reduced by 30 to 95%. After the dedusting step, the gaseous constituents contained in the partly dedusted bypass gas are reduced in a reducing step. The partly dedusted bypass gas is further finely dedusted. The gaseous constituents reducing step includes at least a catalytic reduction of one or more of nitrogen oxides, hydrocarbons, and carbon monoxide.

摘要： A method for controlling an NOx concentration in an exhaust gas in a combustion facility by: measuring a reaction velocity ki of each of a plurality of chars, each corresponding to a plurality of types of pulverized coals; determining a relationship between the NOx concentration in the exhaust gas and the reaction velocity ki for each of the chars; (iii) blending the plurality of the types of the pulverized coal, wherein a blending ratio of the plurality of the types of the pulverized coal is determined by using, as an index, a reaction velocity kblend of the char of the blended pulverized coal, which corresponds to a target NOx concentration or below, on the basis of the relationship; and supplying the blended pulverized coal to the combustion facility as the fuel of the combustion facility.

摘要： An offgas treatment apparatus having a reduction catalyst and an oxidation catalyst downstream of the reduction catalyst may also include a temperature-affecting apparatus for the offgas positioned between the reduction catalyst and the oxidation catalyst. In some examples, the apparatus may include a second temperature-affecting apparatus for the offgas positioned upstream of the reduction catalyst. At least one of the first or second temperature affecting apparatuses may comprise a heat exchanger, a preheating apparatus, an auxiliary heater, or a mixing-in device for a fluid, for instance. In some examples, the apparatus may involve a dust filter positioned upstream of the reduction catalyst.
