- ItemАнализ методов диагностирования технического состояния магистральных теплосетей(The Scientific Heritage, 2017-08) Бабак, Виталий Павлович; Запорожец, Артур Александрович; Ковтун, Светлана Ивановна; Сергиенко, Роман Владимирович
- ItemВлияние метеорологических параметров на оптимизацию процесса горения(Научные известия на НТСМ, 2015) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Редько, Александр АлександровичConsidered the influence of meteorological parameters (temperature, pressure, humidity) on oxygen quantitative content in the air. Showed the bias that introduced with not accounting the parameter of the oxygen current concentration in the air during the energy calculations in the power system. On the basis of experimental data established the dependence of oxygen volume concentration in the air from meteorological parameters (temperature, pressure, humidity). Analyzed the seasonal changes of oxygen concentration in the air in 12 European capitals (based on 2014 year): Brussels (Belgium), Paris (France), Berlin (Germany), Vienna (Austria), London (United Kingdom), Helsinki (Finland), Warsaw (Poland), Bucharest (Romania), Prague (Czech Republic), Sofia (Bulgaria), Riga (Latvia), Rome (Italy). Proposed the method for eliminating the methodical error of the excess air ratio measurement based on current oxygen volume concentration in the environment.
- ItemДиагностика технического состояния объектов теплоэнергетики на базе распределенных вычислительных инфраструктур(Научные известия на НТСМ, 2016-06) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Свердлова, Анастасия ДмитриевнаThe presented state of heating energy equipment in Ukraine are considered. Showed the necessity of creation a modern system of such equipment, which will operate with using retrospective data on the basis of distributed computing infrastructures. Analyzed the modern information and analytical systems of thermal power diagnosis. Suggested the criteria for monitoring the state of the heat power equipment on its actual condition.
- ItemИсследование стехиометрической смеси «воздух-топливо» горючих и взрывоопасных углеводородов(Научные известия на НТСМ, 2014-06) Запорожец, Артур Александрович; Бабак, Виталий ПавловичAnalyzed the feasibility of incorporation air’s shortage/excess in the control of combustion process of inflammable and explosive hydrocarbones. The mass stoichiometric of air-fuel mixture of organic compounds are calculated. The importance of incorporation obtained data for industrial and municipal power are shown.
- ItemКонтроль процесса сжигания топлива в котлоагрегатах малой и средней мощности с использованием сенсоров кислорода(Научные известия на НТСМ, 2017-06) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Пономаренко, Александр ВасильевичBoiler’s technical condition which are using in communal and industrial power engineering is being analyzed. The method of improving the accuracy of the excess air ratio which based on present level of oxygen’s concentration in the air is offered. The structure of fuel combustion monitoring and directing system is developed. The structure based on fluent speed regulation of ventilator ‘s engine on signals of oxygen sensors in the exhaust gases are elaborated. The results of experimental research of developed system based on boiler NIISTU-5 are showed.
- ItemЭкспериментальные исследования изменения объемной концентрации кислорода в воздухе и его влияние на процесс горения(Научные известия на НТСМ, 2016-06) Запорожец, Артур Александрович; Бабак, Виталий Павлович; Редько, Александр АлександровичThe effect of changes the volume oxygen concentration in the air on the combustion process are showed. Suggested the model for calculating the current concentration of oxygen in air depending from the main meteorological parameters – temperature, absolute pressure and relative humidity. Performed the experimental studies of the daily/seasonal changes of volume oxygen concentration in the air on the basis of direct and indirect measurements. Performed a metrological evaluation of results, confirmed the adequacy of the proposal model. Proposed a formula for calculating the air excess ratio based on the current concentration of oxygen in the air.
