CHRONOLOGICAL STUDY OF CONFIGURATION OF A WATER – BOILED PROTEIN SYSTEM WHEN DRYING

abstract 1221608061 issue 122 pp. 899 – 908 31.10.2016 ru 51
The article presents results of research on drying a slurry consisting of distilled water and finely chopped cooked chicken protein of table eggs. The suspension is placed in a Memmert oven, which has temperature of 60 °C. In the process of removing moisture when drying the slurry of water - boiled protein we examined kinetics of its drying and performed chronological photographing of conformation of the system of water - boiled protein. The final weight of the protein remaining after evaporation, was 0.06 g corresponding to 26% by weight of cooked protein source in an amount of 0.23 g. The analysis of the system appearance including the evaporation of the water showed that the protein was originally white, and this color does not undergo any changes until 35 minutes of drying, i.e. when the main base is water. Upon further drying of the suspension, starting with 40 minutes, boiled protein literally "melts" in the surrounding water residues; and as it is disappearing, becoming more and more transparent. Meanwhile, the forms of the protein are becoming round and transforming into the form of liquid crystals. The final phase of the protein is a solid transparent film

abstract 1201606075 issue 120 pp. 1146 – 1155 30.06.2016 ru 98
After silage of ash captured by the electrostatic precipitator, we installed the cyclone of NIIOGAZ CN-15-500 for exhaust gas pre-treatment of the ash resulting from the process of burning solid fuels (coal of Donetsk) in boilers of Novocherkassk hydro power plant. The plant cyclone examination was performed in a production environment of Novocherkassk hydro power station comprising 4 cylindrical cyclone element diameters of 500 mm, and is defined by its real effectiveness, which amounted to 91%. After the cyclone, the gas enters the two-bag filter FRKI-90KP3-2-2 designed to trap solid ash residues and installed over the silo dry ash. Filters are manufactured in climatic design for temperate and cold climate with the accommodation category 4. The article shows the characteristic of the test results and bag filters FRKI- 90K-P3-2-2 before and after the cyclone in the cleaning system. The work presents the analysis of the composition of the ash and compares it with published data. It is experimentally proved that the inclusion of Cyclone CN-15-500 in the process diverting gas purification scheme allowed more efficient operation of fabric filters, reducing the dust significantly for the input gases

EXPERIMENTAL STUDY OF HEAT AND MASS TRANSFER DURING DRYING OF PROTEIN SOLUTIONS IN THE CASE OF FORCED CONVECTION

abstract 1211607047 issue 121 pp. 825 – 834 30.09.2016 ru 85
We have performed an experimental study of the evaporation process at a temperature of 105 ° C for the egg white model solution in distilled water to evaluate the ratio of the heat transfer coefficient from air to water ratio mass transfer to the water surface into the air by evaporation from the free surface in a forced convection. Evaporation of the solution was carried out in a Memmert oven of class Basic (Germany) equipped with forced air circulation, the control panel with a display and a temperature control device. To determine the surface temperature at which the main evaporation of water from the process solution, the experiment conducted under the same conditions by measuring the average temperature of the layer of water sample, placed in a Petri dish in an oven with a sensor - DMM Mastech M838 series. It is found that the coefficient of heat transfer from air to water almost a thousand times greater than the coefficient mass transfer from the water surface into the air

abstract 1271703063 issue 127 pp. 895 – 904 31.03.2017 ru 88
When combustion of fuel in thermal power plants, combustion products are formed, which contain: fly ash, particles of unburnt pulverized fuel, sulfuric and sulfur dioxide, nitrogen oxide, gaseous products of incomplete combustion, sodium salts, soot particles, calcium dioxide, etc. Getting into the atmosphere, they cause great harm to the components of the biosphere. The article presents a laboratory analysis of industrial emissions into the atmosphere of 1-7 power units for 2015 and 2016 at Novocherkassk State District Power Plant. The components NO2, NO, CO, SO2, C (soot) have been determined. It is established that for the whole observed period of excess of maximum permissible emissions was not revealed. Emissions of each of the components are within the same level and are stable
