- (Contens №5 2020)
- ... Methodology. Determination of ultimate compressive strength and crushability resistance was carried out on samples with dimensions of Æ50 ´ 50 mm. The samples were prepared from mixtures of quartz sand and 5 % by weight of binder material (sand-sodium-silicate mixture, phenol-formaldehyde resin), as well as quartz sand cladding with sand-sodium-silicate mixture. Sand-sodium-silicate mixture carbonization kinetics was studied in a layer of hollow glass balls, previously clad with liquid sodium sand-sodium-silicate mixture. Excerpt and determination of ball mass as per duration of their staying in the air were carried out in a climatic chamber. Ball surface appearance was recorded by microscopic photographing with an up to 25 times magnification. Influence of materials-modifiers on dehydrated sodium silicate solute carbonization was investigated by visual assessment of cladding layer surface of glass balls. For this matter, glass balls of Æ10 mm were cladded with pure or modified sodium silicate solute followed by air drying for 6 hours. Cladding layer surface quality was evaluated after 48 hours of exposure in the climate chamber at 24–28 °C with 60–85 % relative humidity. ...

- ... Findings. The thermal and humidity characteristics of the exhaust gases at the mouth of the chimneys were studied at used dry and heated air to reduce the humidity of these gases with a wide temperature change. Under the conditions considered, the main parameters of the chimney anti-corrosion protection systems were determined to prevent condensation in them under normative operating conditions of these chimneys. Based on the values of the obtained parameters, a comparative analysis of the effectiveness of the considered methods for protecting gas exhaust paths for various heat-recovery plants was performed. It is shown that for heating boilers, the use of the air method is most effective in complex-heat recovery systems, characterized by the use of recovered heat to heat the return heat-network water and combustion air ...
