The efficiency of exhaust system in the wooden floor production: A Case study

Wood particles (sawdust, wood dust, etc.) are a constant problem in the wood industry. This can be handled by installing a central exhaust system which removes wood particles from the processing place and the working environment. The objective of analysis of existing exhaust system of wood particles in wooden floor production was to determine the exhaust system efficiency. Based on the measurement and calculation of required parameters (air velocity and partial static pressure) it is determined the fan operating point of four fans, an analysis was made of all pipelines on the suction side of the existing exhaust system and a new construction is proposed regarding the new calculations. By comparing the present system calculations to the new ones, oversize fan power with small efficiency and low partial static pressure are found. This research enables an optimization of the exhaust system, but also can reduce the electric power consumption.
