| 20100095873 | Method for pretreating charges contaminated with carbon carriers - In a method for pretreating charges contaminated with carbon carriers such as, for instance, carbon-carrier-contaminated earths, soils, rocks or minerals having low calorific values for use in clinker kilns, the mentioned charges are introduced into a reactor ( | 04-22-2010 |
| 20100065978 | METHOD FOR THE TREATMENT OF FISSURES IN CONCRETE STRUCTURES - A method for the treatment of fissures in concrete structures by means of repairing them with microcement-based material, comprising a method wherein the fissures, both horizontal and vertical or inclined fissures, are identified and analyzed. The treatment of the mentioned horizontal fissures comprises cleaning them and drying their surface using compressed air and subsequently filling them by means of gravity, the grout being poured with the help of a “pset”. The vertical or inclined fissures are treated by demarcating the sites for drilling and inserting the injector nozzles that permit cleaning and saturating the fissures with water, followed by the injection of the microcement grout under pressure.

| 20090136886 | Method and Device for Removing Volatile Organic Components From Waste Gases of a Clinker Installation - In a method for removing volatile organic components (VOC) from waste gases of a cement clinker kilns installation, in which the largely cooled waste gases are subjected to post-combustion, a post-combustion is carried out to an extent as to ensure a reduction of the concentration of the VOC below the admissible threshold values. The post-combustion is carried out for the production of vapour, whereby the production of vapour in the post-combustion is dimensioned for a gas volume to be post-combusted, ensuring that a partial quantity of the waste gas corresponding to the gas volume allows for the reduction of emitted VOC per unit time in the waste gas below admissible concentration values by rarefaction and whereby this partial quantity is simultaneously dimensioned for the production of a amount of vapour sufficient for the economical operation of a given steam turbine. The device for carrying out said method is characterized in that a branch line is connected to the waste gas line of the cement clinker kiln installation, between the pre-calciner and the waste gas suction fan, to which branch line a combustion chamber for a heat exchanger for the production of vapour and a steam turbine are connected. The invention also relates to a device for carrying out said method, characterised in that a branch line is connected to the waste gas line of the clinker installation, between a preheater and the waste gas suction fan, a combustion chamber for a heat exchanger for producing water vapour and a steam turbine being connected to said branch line. | 05-28-2009 |
