SNCR: when the equation no longer holds
There are plants where selective non-catalytic reduction (SNCR) does not achieve the expected DeNO X results for no apparent reason. Often a look at the chemical processes in th...
Staged combustion deNOx technology for calciners Premium
Under increasingly stringent pollutant emission standards, deNO x systems are widely used in Chinese cement production. As the calciner is relatively flexible and adjustable in ...
Lowering the temperature Premium
Clinker production is a high-temperature combustion process that generates nitrogen oxides (NO x ), one of the most significant kiln emissions. To reduce these emissions, select...
Achieving AF and NOx goals Premium
With reducing fuel costs and sustainability in mind, Brazilian producer Cimento Nacional is persistently striving to implement innovative methods to increase alternative fuels (...
Injecting new life in NOx control Premium
The aqueous ammonia (NH 3 ) injection system for nitrogen oxide (NO x ) emission reductions at a cement plant in Florida, USA, provided limited ability for flow downturn and mat...
Gaseous emission control Premium
With acid gas emissions being one of the topics of this ICR issue Dr Clark reflects on previous Technical Forums on this subject and the latest offerings from WL Gore in this re...
