Cement manufacturing plant and method of operating cement manufacturing plant
A cement manufacturing plant comprises a raw mill, at least one preheater string, a clinker furnace, and a clinker cooler comprising a first section and a second section, where a preheater exhaust gas recirculation device is provided for recirculating exhaust gas exiting the at least one preheater string into the first section of the clinker cooler, and where the clinker cooler is provided for cooling the at least one preheater string into the second section of the clinker cooler. The cement plant is configured for switching between an air mode of operation and an oxyfuel mode of operation, comprising a first switching device for connecting an air source or an oxygen-enriched gas source to a combustion zone of a clinker furnace burner, and a second switching device for establishing or separating a connection of the preheater exhaust gas recirculation device to the first section of the clinker cooler.
一种水泥制造设备包括生料磨机、至少一个预热器串、熟料炉以及包括第一部段和第二部段的熟料冷却器，其中，预热器废气再循环装置设置成用于将离开该至少一个预热器串的废气再循环到熟料冷却器的第一部段中，并且其中，该水泥设备构造成用于在空气操作模式和氧燃料操作模式之间切换，包括用于将空气源或富氧气体源连接到熟料炉燃烧器的燃烧区的第一切换装置，以及用于建立或分离预热器废气再循环装置与熟料冷却器的第一部段的连接的第二切换装置。
