The problem of rational energy use is directly related to sustainable socio-economic and technological development, so its solution is a complex priority. Energy efficiency in modern industry is achieved through the improvement of management methods and the use of energy-saving technologies. The aim of this work is to analyze the possibility of reducing energy consumption in the technology of wood fire-retardant impregnation after incomplete drying. The study uses experimental methods and methods of mathematical modeling. It is established that the efficiency of wood impregnation according to the criteria of time and energy consumption increases with a decrease in the time interval between the drying completion and the impregnation start, and also depends on the degree of pre-drying, which should be sufficient, but not excessive. The adequacy of the results is confirmed by their consistency with the known literature data.
The article deals with the problem of improving the technology of wood impregnation. Mathematical modeling is used as a research tool. Using the logistic approach, the calculation formulas are obtained in which the properties of wood that affect the laws of impregnation are considered in an integral form. The adequacy of the simulation results is confirmed by their consistency with experimental data for samples of aspen wood. By means of the developed model the analysis of laws of impregnation is executed and quantitative estimations of the simulated process are obtained. It is established that the concentration of impregnating liquid in the wood increases almost linearly at the initial stage of impregnation, and the duration of this stage in the simulated process is about two minutes. However, according to the instructions of the manufacturer of the impregnating liquid, impregnation should be carried out by immersion in the solution for 60 seconds, which is less than the duration of the rapid impregnation stage. This means that to improve the quality of impregnation and economical consumption of impregnating liquid impregnation should be carried out by immersion for at least 120 seconds. The research prospects are connected with the specification of the model parameters depending on the wood species and impregnation technology.
