Electricity generation based on biomass incineration is a substantial element of the energy mix and plays an important role in the decarburization of the energy sector. Biomass as a fuel has a variety of forms and a wide range of physical and chemical characteristics that must be addressed correctly before selecting a combustion technology. In the past, circulating fluidized bed (CFB) boilers allowed for mono and co-incineration of biomass in small industrial and large commercial power generation applications. Now, CFB solutions became the technology of choice for fulfilling the governments’ targets of increasing the share of renewable energy in national plans affecting the energy transition. In this context, the reduction of the CO2 footprint will remain a critical topic. Given this background, the number of biomass project will increase with a strong competition between developers leading to a consistent application of best available technologies (BAT) and highest efficiencies of the plants. Incentives set to steer the biomass market, such as, Feed in Tariffs (FiT) are expected to decrease in the future. A CFB inherent combination of highest possible plant performance, acceptable investment cost and operational flexibility is available now. This paper presents the design aspects of biomass CFB boilers by considering the selection of steam conditions, process design and specifics of boiler auxiliary equipment selection, as well as, emissions control systems for biomass application. In this context, the experience with CFB boilers working with high steam conditions will be presented.
