FLUE GAS CLEANING TECHNOLOGY

HoSt’s flue gas cleaning technology is applied for the lowest emissions and to meet the most stringent emission requirements. HoSt is a forerunner and industry leader in this field and has developed the cleanest NO-NOx technology, resulting in the cleanest plant by minimizing NOx, Sox (sulfuroxides), HCl (hydrochloric acid), dust and other pollutants to meet required emission standards anywhere. Our proven gas cleaning techniques, continuous innovation and strict emission standards limit the emissions from firing biomass to a minimum.

Very low emissions can be realised with the HoSt flue gas cleaning system. By default, HoSt includes a multicyclone and bag house filter to reduce the dust emissions. Extreme low NOx emissions can be realised by the combination of combustion control, urea injection, and the DeNOx catalyst: the well-known NO-NOx technology, in-house developed by HoSt and successfully applied in current projects. The concentration of sulphur and chlorine components in the flue gas can be reduced by installing additive injection. The NO-NOx flue gas cleaning technology is a best available technology and results in the lowest measured emissions of biomass-fired heat and power plants ever measured in the Netherlands.

Our proven gas cleaning techniques and continuous innovation limit the emissions from firing biomass to a minimum. Extensive and advanced flue gas cleaning ensure that our modern biowaste-fired energy installations emit very few contaminants. Thanks to the bag house filter, which ensures filtering dust separation, and extensive flue gas cleaning technology, such as a DeNOx catalyst and urea injection into the furnace, our biomass-fired plants have guaranteed low dust emissions and nitrogen oxide emissions.
