A cooler for cooling bulk material, in particular cement clinker, may include a cooling gas chamber through which a cooling gas flow for cooling the bulk material can flow in crosscurrent, and a conveying device for conveying the bulk material through the cooling gas chamber in a conveying direction. The cooling gas chamber may include a first cooling gas chamber portion with a first cooling gas flow and a second cooling gas chamber portion, adjoining the first cooling gas chamber portion in the conveying direction of the bulk material, with a second cooling gas stream. The cooler may include a separating apparatus for gastight separation of the cooling gas chamber portions from one another. The separating apparatus may have sealing element and at least one suspension element, to which a plurality of sealing elements are attached.

Cooler for cooling bulk material, in particular cement clinker

A cooler for a cooling clinker of a cement production plant includes an aeration grate for conveying the clinker in a conveying direction, a ventilator for generating a cooling air flow that passes the aeration grate as a cross flow, and a measuring plane disposed above the aeration grate. The measuring plane includes a temperature measuring installation for ascertaining a temperature distribution in the measuring plane. The cooler includes an open-loop or closed-loop control installation to control a conveying rate of the clinker and/or a flow rate of the cooling air flow as a function of the ascertained temperature distribution. Further, a corresponding method can be utilized to operate a cooler for cooling clinker.

Cooler for cooling clinker and method for operating a cooler for cooling clinker

A method for processing material that contains cement rock may involve comminuting the material in a first comminuting device, feeding the material to a reactor in which the material is mixed with an aqueous liquid and COand in which a mixing movement of the material is generated, and removing the material from the reactor and subdividing the material into at least two fractions by way of a classifying device. The temperature and the pressure in the reactor are maintained such that the pressure exceeds atmospheric pressure and such that the temperature is greater than 100° C. The method may further involve removing a withdrawal stream of the aqueous liquid from the reactor and separating and discharging suspended particles of the material from the withdrawal stream.

Method and facility for producing material containing hydrated cement

Processes and plants for producing cement clinker, in which an oxygen-containing gas having a proportion of 15% by volume or less of nitrogen and a proportion of 50% by volume or more of oxygen is conveyed from a first section of the cooler directly adjoining the top of the furnace into the rotary furnace and is optionally additionally conveyed to the calciner, and where the total gas streams fed in to the combustion processes consist to an extent of more than 50% by volume (preferably more than 85% by volume) of oxygen.

Oxyfuel clinker production with special oxygen addition

Processes and plants for producing cement clinker, wherein no recirculation of preheater exhaust gases occurs and the ratio of solid fed in to exhaust gas in the preheater is set to greater than 1.0 kg of solid to gas.
