New Developments of an Effective SNCR Control System Incorporating the NOx Mass Flow Profile
The NOx reduction rates which have been achieved in recent years using non-catalytic technologies (SNCR) have proved to be reliable even in applications which were believed to work only with the more costly SCR process in the past. In the meantime, SNCR has advanced to be the Best Available Technology (BAT) in grate-fired combustion plants.
In power plants, NOx emissions of 200 to 250 mg/Nm³ in the flue gases can be obtained by applying primary measures alone. An additional reduction below the actual emission level of 200 mg/Nm³ is more and more often realized by using SNCR technology. Due to their size and operating conditions power plant boilers have more complex requirements than Waste-to-Energy plants. Therefore, further steps are needed to catch up with the advances that the SCR process still has over SNCR. This paper describes where the SNCR technology stands today and in which areas there is further potential.

Use of a Fabric Filter for the Sorption – What Has to be Considered? – Experiences and Solutions –
© Thomé-Kozmiensky Verlag GmbH (9/2016)
In almost all flue gas cleaning systems installed at WtE-plants, the fabric filters are central components. A good example for this is the conditioned dry sorption process which is currently preferentially used in Europe. Within the filter not only the particles and the particulate heavy metals are separated from the gas flow, but also all reaction products resulting from the separation of gaseous pollutants such as HF, HCl, SOx, heavy metals and in this respect particularly Hg as well as PCDD/PCDF. In addition to this the fabric filter constitutes an excellent reaction chamber with high additive powder density in the filter cake.
Infrasound Solution for Fouled SCR and the Economizer in World’s Largest Waste-to-Energy Boiler
© Thomé-Kozmiensky Verlag GmbH (9/2016)
Infrafone, with headquarters in Stockholm, Sweden, is using infrasound as a soot cleaning method and has plenty of experiences from various fuels and applications. The technical development has resulted in a product with much higher acoustic power than any other similar products on the market and acoustic modelling software that is unique. Infrasound cleaning increases the efficiency, the availability and the lifetime of industrial and marine boilers. In this text we start by describing the properties of infrasound and the product, while finishing by looking deeper into a couple of recent results obtained on waste to energy boilers.
Significance of and Challenges for Flue Gas Treatment Systems in Waste Incineration
© Thomé-Kozmiensky Verlag GmbH (9/2016)
Flue gas cleaning downstream of waste incineration plants had its origins in the increased construction and deployment of such plants to counter rising air pollution in the nineteen-sixties. Back then, the ever-growing burden on the environment caused lawmakers to start enacting emission limits for air pollution control. An unceasing series of environmental scandals and increasingly better analytical methods and measuring instrumentation led to a constant reduction of the emission limits and, consequently, to ongoing adjustment and further development of the necessary process stages in flue gas cleaning. As a result, today minimum emissions can be reached even under the challenging condition of deployment of a very inhomogeneous fuel (waste) and, hence, waste incineration today is no longer a key contributor to air pollution. Today, the need for flue gas cleaning is not called into doubt anymore and has long become a matter of course in the industry and in society at large. Apart from ensuring efficient elimination of noxious gases, the focus of today’s further developments is on issues such as energy efficiency, minimization of input materials and recovery and recycling of by-products from flue gas cleaning as valuable raw materials. These issues are also deemed to be key challenges, especially when it comes to selecting sites for new plants in such a manner that potential synergies can be exploited. Such aspects will also have to be considered in the plans for the predicted mega-cities of the future.

All over the world people understand that reducing air pollution is essential to increase health and comfort of people. Nitrogen oxides (NOx) are among the main components of pollutants caused by combustion processes. It is toxic by direct contact and it causes acid rain.
