Abstract (en)

[origin: WO2019154723A1] The invention relates to a method for operating a calciner (16) of a cement production system, having the steps of: - ascertaining a temperature distribution on at least two measurement planes (34, 36) within the calciner (16), and - regulating/controlling the quantity of fuel (30), preheated raw meal (14), and/or combustion air (32) in the calciner (16) depending on the ascertained temperature distribution. The invention also relates to a calciner (16) of a cement production system, comprising a combustion chamber (44, 46), wherein the combustion chamber (46) is equipped with at least one inlet (48, 50, 64) for introducing the preheated raw meal (14) into the combustion chamber (44, 46), at least one fuel inlet (52, 54, 60) for introducing fuel (30) into the combustion chamber (44, 46), and at least one air inlet (56, 58, 62) for introducing combustion air (32) into the combustion chamber (44, 46). At least two measurement planes (34, 36), each of which has at least one temperature measuring device (40) for ascertaining a temperature distribution on the respective measurement plane (34, 36), are arranged in the combustion chamber (44, 46), and a control/regulating device is provided which is designed to control/regulate the quantity of preheated raw meal (14), fuel (30), and/or combustion air (32) into the combustion chamber (44, 46) depending on the ascertained temperature distribution.
