Frans van Dijen

Frans van Dijen is a senior expert in combustion and emissions in power stations and co-generation units. He has experience with design, efficiency and troubleshooting of boilers and flue gas cleaning installations. He is also experienced with waste incineration and fuel conversion technologies. As a multidisciplinary expert within ENGIE Laborelec, his daily consulting activities in the field of combustion and emissions cover topics such as improvement and troubleshooting of combustion, conversion of boilers from coal to biomass, questions related to ash analysis and valorization, prevention or correction measures against slagging and catalyst evaluation and management for SCR denox installations.



This advanced course provides participants with the necessary knowledge for a detailed understanding of circulating fluidized bed combustion, its mechanisms, typical operational problems, efficiency, corrosion, materials, environmental aspects and many more.
