More than 10 years of experience with over 40 full-scale trials
The experience of KEMA related to co-firing is based on hands-on experience with co-firing for more than 10 years. During that period KEMA was involved in over 40 full-scale trials in coal-fired power plants with a broad range of fuels. Based on this experience the following services have been developed by KEMA. Co-firing model
A model incorporating the influence of fuel quality on power plant operation, ranging from fuel handling, slagging and fouling, combustion efficiency, efficiency of flue gas cleaning installations, ash quality and emissions. Spontaneous heating
When storing large amounts of biomass, there is a serious threat of spontaneous heating. KEMA has gained substantial knowledge and experience regarding this process and the influence of material properties and storage conditions. We can help you with issues regarding prevention and control of this phenomenon. NOx emission and DeNOx operation
KEMA developed models for design and operational aspects of NOx-reduction technologies. When co-firing is applied this can influence the combustion conditions and thus the formation of NOx. On the other hand, when an SCR installation is applied for NOx reduction, catalyst life time can be influenced due to inactivation. We offer a broad spectrum of assistance on this subject. Corrosion monitoring
Corrosion in vital components is a continuous cause for concern in coal-fired power plants. Co-firing can lead to a serious increase of this threat. KEMA has developed a simple but effective method for early corrosion and fouling detection of waterwalls in a boiler. For co-firing situations the KEMA tools for early corrosion detection are effective to prevent serious damage to your installation. Fuel quality and emissions
The KEMA TRACE MODEL® is developed to calculate the consequences of coal firing and co-firing of secondary fuels with respect to ash quality and emissions. Results of model calculations are used in official documents in discussions with governmental authorities, in environmental impact statements and in license applications. Ash quality and industrial application
For coal-fired power plants in the Netherlands industrial application of by-products of the coal combustion process (coal ashes and FGD residues) is essential. Co-firing can influence the quality of these by-products. KEMA is actively involved in research, testing and optimization of co-firing influences. We do not work in isolation, but co-operate closely with research partners across Europe, construction companies, and with the end-users of concrete structures. Want to know more?
