Streamlining China’s cement industry

17 September 2018, Published under Cement News

With China’s cement industry due to reduce its energy use and emissions to levels set out in the country’s 13th Five-Year Plan, South Cement’s Vice Chief Engineer, Chen Yourong, looks at the technological options available to the industry to achieve the plan’s targets by 2020. By Chen Yourong, South Cement Co Ltd/CNBM Group, China. China’s policy makers have set ambitious targets to lower the domestic cement industry’s energy intensity and emissions to the atmosphere by 2020 ...

Finding the missing link

13 December 2017, Published under Cement News

In 2015 Çimsa Çimento’s Mersin plant, Turkey, suffered an increasing number of cyclone blockages, causing severe interruptions to the facility’s grey cement Line 1. After unsuccessful attempts to find the reason for the blockages, a kiln inlet process gas measurement system from sick was installed to provide the missing link between the sulphur content in the kiln process gases and unwanted production downtime. By Felix Bartknecht, SICK AG, Germany, and Sezin Arıkan, Çimsa Çimento Mersin, T...

Kiln emissions – more than just hot air

01 February 2017, Published under Cement News

In last month’s Technical Forum we promised to return to the topic of cement kiln emissions, which were said to be both simple and complex, benign and noxious. The challenge is to see the broad simplicity, which then allows the increasing complexity to be understood. By Dr Michael Clark, UK. Kiln emissions include a wide range of gases – some benign but others noxious At the macro level cement kiln emissions are indeed simple. The raw materials used for manufacturing clinker are...

Cyclic processes

10 July 2013, Published under Cement News

The Technical Forum has covered the topic of the cyclic processes taking place in a cement kiln on a number of occasions over the last 15 years. Regular readers may think that there is not much more to be said on the subject. However, these processes remain one of the most frequent sources of questions and, therefore, it is perhaps time to revisit this topic. In one of the many cycles operating in a cement plant, alkali salts evaporate in the burning zone and are carried back to th...

Lowering NOx and SO2

19 December 2012, Published under Cement News

There are several options for reducing NOx and SO2 in the cement pyroprocess. However, the solution selected must be both cost-effective and flexible in terms of raw materials, fuels and operating conditions. Making the correct choice requires the necessary process know-how and advanced technical solutions to handle NOx and SO2 emissions at all levels. FLSmidth is one of the few companies to offer both. Lars Schultz explains. Dialogue between FLSmidth specialist and customer, SNCR inj...
