- Due to energy crisis as well as increasing pollution of the enviroment, renewable energy sources usage increases all over the world. These facts encouraged authors to start research over developing a uniform biomass boiler calculation model. Paper presents the design of biomass boiler assembly created for the organic Rankine cycle unit since these systems could achieve strong position in energy industry. To achieve optimal performance of boiler assembly, two additional devices have been designed: the economizer and air preheater. Such installation allows to reach the assembly efficiency of 82%. The research over the air nozzles placement in the combustion chamber in order to ensure the best firebox efficiency is also presented. Modeling is based on computational fluid dynamics simulations of pyrolysis on the moving grate. Released gases are being transported to the combustion chamber, mixed with air from the nozzles and combusted. Furthermore, the model assumes different distribution and composition of gases across the moving grate.
