To SCR or SNCR?21 November 2022, Published under Cement NewsWhile in some cases the choice between SCR and SNCR technology for NOx reduction appears straightforward, there is a middle way that enables the use of the less expensive option of SNCR technology. Lechler explains how cement producers can benefit from its high-efficiency SNCR technology. By Dipl Ing Claus Fritze, Lechler, Germany. Figure 1: structure of the APC Process Proven technologies for the reduction of NO x emissions, in addition to primary measurements, are either the... |
Game changer in the kiln08 November 2022, Published under Cement NewsIn today’s operating environment, the refractory lining in the safety zone of a kiln needs to accommodate the requirements of alkali resistance and energy-saving properties. A new brick by Refratechnik is designed to become the link between established refractory products for this zone, making it a game changer for the kiln. By Lutz Derks, Refratechnik Cement GmbH, Germany. Refratechnik Cement GmbH’s kronal® 60 ar is a newly-developed refractory brick for the safety zone in the ki... |
Adapting calciners for decarbonisation01 November 2022, Published under Cement NewsThe drive to decarbonise cement kiln lines has led to new research that looks at the use of hydrogen and plasma flames in co-firing with biomass. While this new technology requires modifications to the calciner and burner sections, recent R&D investigations open the door for lower-carbon kiln firing. By Tahir Abbas and Michalis Akritopoulos, Cinar Ltd, UK. Figure 1: the swirling imparted by the tertiary air (TA) to the upward moving riser duct stream in the calciner is shown by ... |
Tapping ultimate WHR potential25 October 2022, Published under Cement NewsReducing the carbon footprint of cement production and introducing captive electricity generation have become priorities for Turkish cement producer Nuh Çimento. After nine years of waste heat recovery (WHR) experience at its Hereke cement works, the company has gathered a considerable amount of data that can be used to assess WHR efficiency and tap its ultimate potential.
