Description
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

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

REDUCTION OF NOISE OF ENVIRONMENTAL POLLUTION BY INSTALLING SILENCERS
DescriptionThe article describes the sources of noise Yeisk thermal power plant (TPP) in excess of the permissible sound pressure levels in homes on the street. Gorky, 25. Eisk TPP is located near the residential area, where the permissible noise level standards adopted much more stringent than in the power plants. Prolonged exposure to noise leads to human disease noise disease. The scheme of movement of exhaust gases from the thermal power plant generating units Yeisk. Analysis of measurements of noise characteristics of main and auxiliary equipment showed that one of the main sources are sectioned estuaries double-barrel pipe height of 27 m and slices estuaries pipes emergency explosive valves flues installed on the roof at a height of 17 m. The previous Noise reduction nozzles that emit noise uniformly in all directions are replaced by advanced, whose index changed direction estuaries sections double-barrel tubes. This will change the level of radiated noise in residential development. If you change the angle of orientation of 135°-180°, the noise level in residential construction decreased by 7-10 dB. Shows a photograph of thermal power plants, residential buildings, the old and improved silencers

Description
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
