Numerical Simulation of Biomass and Waste Combustion Plants

Industrial production of heat and electricity due to combustion of complex fuels, such as biomass and municipal solid waste, is often accompanied by undesirable phenomena. Among others, deposit build-up, pollutant formation and inefficiency are challenges that arise during system operation. First of all, slagging and fouling are major causes for increasing operation costs. With highly detailed simulation concepts we provide you extensive insights into the combustion process and assist you in process optimization.

Simulation Techniques

As an experienced service company in the field of CFD simulation we offer a broad range of simulation concepts in order to meet our customers’ requirements. Short-term analysis of packed bed combustion can be carried out with state-of-the-art packed bed models and steady state CFD simulation of the freeboard and heat exchanger sections.

For deeper insights we also provide our partners the highest level of detail for packed and fluidized beds on the basis of discrete particle methods.

Discrete Particle Approach (CFD and DEM)

Discrete particle methods allow for consideration of movement and conversion of individual fuel particles. In our unique simulation concept this is achieved by coupling of CFD simulation, Discrete Element Method (DEM) and a particle model for thermally thick fuel particles. The latter comprises drying, pyrolysis and char burnout as the main steps of the thermal conversion.

A key benefit of our procedure lies in its ability to represent fuel heterogeneities.
