Description
A considerable share of global electricity generation is still generated by conventional power plants. Here, compliance with permitted emission limits for nitrogen oxides represents a challenge for power plant operators. Nitrogen oxides develop in side reactions in the combustion process. So far, primary and secondary measures have been applied in denitrification in order to reduce these emissions from combustion plants and ensure an environmentally friendly provision of energy. Primary measures, such as phased air supply, are applied directly in firing. If these are not sufficient to comply with the legal limits, secondary measures such as selective non-catalytic reduction (SNCR) are subsequently carried out. Nitrogen oxide already formed in firing is broken down to water and nitrogen – two natural components of air – by injecting ammonia or urea. A research team of KIT has now developed process for reducing nitrogen oxide in dust or solid fuel firing systems that is intended to replace secondary measures and thus reducing the use of inputs. Here, a periodic interruption of fuel supply to the combustion chamber creates a pulsating flame. The pulsation of the flame demonstrably produces up to 50 percent less nitrogen oxides. A corresponding device in the burner structure (oscillator) ensures a batchwise supply of the air and fuel mixture. The pulsation frequency depends on the operating conditions. A further positive aspect of pulsation is the increase in combustion intensity and flame volume, which significantly improves heat transfer. The pulsation effect is achieved by interval-wise regulation of primary air supply.
You can get an overview of this technology at KIT stand. More details can be exchanged individually with the responsible scientific employees of KIT after the industry fair.
