Optimization of the firebox of a biomass-fired boiler

The most common fuel in crop drying is natural gas. Replacing this for renewable energy is both environmentally and economically beneficial. As a by-product of crop cleaning during harvesting, a source of energy suitable for combustion can be obtained from plant parts that are otherwise treated as waste. Solid fuel requires a special fuel system. Our goal is to find an optimized design for cleaning waste based on the existing solid fuel boilers, and in the framework of this work, the optimal design of the fire box passages is our narrower goal. To do this, we use CFD modelling, which is used to estimate the flow characteristics based on a 3D model in addition to the known operating parameters. By modifying the geometry between given boundaries, we find the ideal design within the boundaries allowed by the construction.
