Design and distribution of air nozzles in the biomass boiler assembly

Abstract

Due to energy crisis as well as increasing pollution of the environment, renewable energy sources usage increases all over the world. These facts encouraged authors to start research over developing a uniform biomass boiler calculation model. This paper presents a design of biomass boiler assembly created for ORC (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 paper also contains research over the air nozzles placement in the combustion chamber in order to ensure the best firebox efficiency. Calculations are based on CFD modeling 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.
