Item type:Publication, Analysis of heat and steam consumption during artificial convective drying of oak sawn timber of different thickness(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2023-09); ; ; ; In the paper, the consumption of heat and steam of oak sawn timber with a thickness of 25,0 and 50,0 (mm) are analyzed under conditions of classic convective drying. The drying mode is compiled on the basis of data on the temperature of the drying agent (air), the relative humidity of the air and the speed of air movement in accordance with the current value of moisture in the wood. The heat consumption is analyzed in all stages of the drying cycle such as heating the wood, active drying of the wood, equalization of the average moisture in the wood and conditioning, i.e. equalization of the moisture in the cross-section within ± 2.0 (%). The moisture content of sawn timber at the beginning of drying is about 55,0 (%) and at the end of drying is 10,0 (%). The sawn timber are intended for the production of solid wood panels. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Analysis of heat consumption during convective wood drying of beech sawn timber of different thickness(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2025-09); ; In the paper, the heat consumption of beech sawn timber with a thickness of 50,0 and 70,0 (mm) are analyzed under conditions of classic convective drying. The drying mode is compiled on the basis of data on the temperature of the drying agent (air), the relative humidity of the air and the speed of air movement in accordance with the current value of moisture in the wood. The heat consumption is analyzed in all stages of the drying cycle such as heating the wood, active drying of the wood and conditioning, i.e. equalization of the moisture in the cross-section within ± 2.0 (%). The moisture content of sawn timber at the beginning of drying is about 45,0 (%) and at the end of drying is 8,0 (%). - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Analysis of the heat energy used for steaming edged beech lumber (Fagus sylvatica L.) with thickness of 50 mm(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2022-11)Milled lumber steaming is a technological procedure, during which lumber is exposed to the influence of saturated water vapor, temperature and pressure, in a closed system. The purpose of the steaming process is to change the color, improve the properties of the lumber, sterilization, as well as to remove some lumber defects that had occurred during the drying process. This paper presents the results obtained from analysis of the heat energy required for steaming edged beech lumber with thickness of 50 mm. Beech (Fagus Sylvatica L.) is the dominant wood species in primary wood processing industry on the territory of North Macedonia. That being the case, the data related to steaming beech lumber is of particular interest. The heat energy of a metal automated steaming chamber with a capacity of 28 m3/cycle was analyzed. Based on the parameters given, an analysis and technical calculation of the heat energy required for steaming the beech lumber were conducted.
