Turbosorp® for biomass, RDF, EfW
Turbosorp® is the ideal solution for flue gas cleaning downstream of biomass incinerations, RDF-fired boilers or Energy-from-Waste plants.
Process
AE&E’s dry flue gas cleaning processes are based on well proven circulating fluidised bed technology.
The flue gas flows through a turboreactor from the bottom to the top and then enters a downstream particulate control device, which can be either a fabric filter or an electrostatic precipitator. Fly ash from incineration and fresh additives are dosed into the turboreactor, while a large part of the solid material from the reactor is fed back to the fluidised bed as recirculate. Water is also injected to lower the flue gas temperature and achieve higher separation performance. If needed, activated carbon serves to provide excellent heavy metal and dioxin removal. As a result of advanced process management with regard to the operational temperature, solids recirculation and the dosed additives, material consumption and the quantities of residues are kept to a minimum. The product of the process is a dry, powdery residue which – depending on its composition – can be landfilled or used as a filling material, e.g. in road construction after stabilisation.
Low investment and maintenance cost
The Turbosorp® system stands out due to its compact design, which allows valuable space savings. Fluidised bed technology does not employ either rotating, or wear parts. This not only reduces investment cost, but also means minimum maintenance expenditure. Moreover, due to the simplicity of the design of the system components, high levels of availability can be achieved.
