Application of slag from thermal power plant for the production of porous filler / Ihor Mitin, Diana Kindzera, Volodymyr Atamanyuk // Environmental Problems. — Lviv : Lviv Politechnic Publishing House, 2021. — Vol 6. — No 2. — P. 110–116.https://ena.lpnu.ua/handle/ntb/58983The article is devoted to obtaining a porous filler from the slag of the Thermal Power Plant and investigation of the filtration method for the drying of slag and clay as main raw materials for preparing the charge for porous filler production. The possibility of using TPP slag as the raw material for the production of porous filler has been proved. The main benefits of using such wastes in the production process are environmental protection, conservation of raw resources for the production of finished products. According to the results of the research, insignificant values of the pressure drop confirm the application feasibility of the filtration drying as an energysaving method of the drying of slag and clay for preparing the charge for porous filler production. The influence of the temperature of the drying agent in the range from 313 to 373K on kinetic during filtration drying of slag and clay has been established. Obtained results are useful for the organization and intensification of the filtration drying process of slag and clay as the preliminary stage at the porous fillers production line. The qualitative new porous filler with the bulk density of 230 kg/m3 , the specific heat of 0.82 kJ/kg∙K, the thermal conductivity of 0.067 W/m∙K and compressive strength of 27.7 MPa has been obtained which can be used for the production of lightweight concretes.110-116enthermal power plant (TPP)coal combustionash and slag wastesutilizationraw materialsadditiveschemical compositionporous fillerdrying methodsdrying agentporous fillerlightweight concreteArticle© Національний університет “Львівська політехніка”, 2021© Mitin I., Kindzera D., Atamanyuk V., 20217doi.org/10.23939/ep2021.02.110Mitin I.
