Evaluation of fermented waste energetic characteristics and the numerical modelling of nitrogen oxides concentrations during combustion
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)The paper presents the numerical modelling methodology of separated gaseous pollutants concentrations assess and results obtained by comparison with the experiment values. Gaseous pollutants separate when the solid fuel, ... -
Building partitions acoustic properties
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)In this article the sound insulation index Rw of partitions is analysed.Sound partitions are built from various materials: bricks, ceramsite blocks, clay blocks, which differ in their composition, structure, and mass. Walls ... -
Statistical evaluation of relationship between the gravel road dustiness and environmental conditions when mixtures of molasses based solution and CaCl2 for reducing dustiness are used
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)The gravel road dust problem is quite acute. In order to minimize the harmful environmental components, dust reduction tests chosen mixtures with molasses base material and calcium chloride. Mixing CaCl2 with a new generation ... -
