Use of a Fabric Filter for the Sorption – What Has to be Considered? – Experiences and Solutions –

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.

High-efficient sorption technologies are often working with a high re-circulation rate of particles separated at the filter fabric and re-introduced in an upstream installed reactor. Such procedures request a very high efficiency in the range of > 99.9 percent removal rate. In the following the objectives of the fabric filter in WtE-plants are explained. Important aspects regarding design and construction of fabric filter will be considered.

Infrasound Solution for Fouled SCR and the Economizer in World’s Largest Waste-to-Energy Boiler
© TK Verlag - Fachverlag für Kreislaufwirtschaft (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
© TK Verlag - Fachverlag für Kreislaufwirtschaft (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.

New Developments for an Efficient SNCR Monitoring and Regulation System by Evaluating the NOx Mass Flow Profile
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
When the SNCR process was introduced first in the eighties of the last century the focus was directed towards applying this low cost technology mainly in combustion plants where only relatively low NOx reduction rates were required. In these types of boilers, like waste-to-energy plants (WtE), the required NOx limits < 200 mg/Nm3 could be maintained easily. Today, NOx limits of 100 mg/Nm3 and lower can be achieved and guaranteed at all operating conditions for these applications. Therefore, the SNCR process represents the Best Available Technology (BAT) today. As a result, more and more owners of waste-to-energy plants take advantage of the low costs at comparable performance and replace their existing SCR system with SNCR.

CO2 Capture and Re-Use at a Waste Incinerator
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Recently a new innovative process developed by Procede Gas Treating B.V. has been commissioned at line 3 of the Twence plant, a Waste-To-Energy (WTE) plant located in the eastern part of the Netherlands. In this process the CO2, that usually is emitted to atmosphere, is in this new application, scrubbed from the flue gas and the obtained pure CO2 stream is used to produce a sodium bicarbonate slurry (SBC). Instead of the conventional SBC flue gas scrubbing process, where dry SBC particles are used, this SBC slurry will be injected to remove the acid components from the flue gas, before the gas is emitted to atmosphere. Due to the implementation of this process the carbon footprint of the Twence installation is reduced. The new SBC plant produces 8,000 tons of sodium bicarbonate annually and to produce this amount of SBC 2,000 ton per year CO2 is captured from the flue gas. The CO2 originates for about 50 percent from biomass.
