NOx in the mass balance

14 August 2013, Published under Cement News

Dr Clark discusses how NOx emissions fit into the mass balance of a cement kiln. How do they arise and how can they be controlled and mitigated? Organic nitrogen compounds in the fuel used to fire the cement kiln will be oxidised to NOx in the kiln’s main burner and precalciner During 2012 a popular series of workshops were held in conjunction with the Cemtech Dubai, Jakarta and Geneva conferences on the topic of the fundamental mass balance of a cement kiln. The workshops fe...

Balancing volatile behaviour

28 May 2012, Published under Cement News

Following on from last month’s Technical Forum about the impacts of alternative fuels and raw materials, Dr Michael Clark examines the effect on kiln emissions, using the mass balance of the cement kiln as a starting point. Metallic mercury and mercury compounds are too volatile to pass down the preheater into the rotary section of a kiln What goes into the cement kiln must either come out in the clinker product or the emissions from the kiln, or it must be retained and built...
