DETERMINATION OF QUANTITATIVE AND QUALITATIVE ASPECTS OF ENVIRONMENTAL POLLUTION BY THERMAL ENERGY FROM POWER PLANTS WITH RECIPROCATING INTERNAL COMBUSTION ENGINES

Abstract

In the article, which shows the results of the authors' own research, the purpose of which was improving the method for taking into account the parameters of the emission of thermal energy in the environment as a pollutant during the criteria-based complex assessment of the ecological safety (ES) level of the exploitation of such power plants (PP), especially taking into account the realities of the functioning of the divisions and institutions of the SES of Ukraine and their units of fire-fighting and emergency rescue vehicles (FERV) in conditions of armed aggression and in the perspective of the post-war reconstruction of critical infrastructure and the economy of our country. Following tasks were consistently solved: development of a method for calculating the values of the complex fuel-ecological criterion taking into account thermal energy emissions in the environment during the operation of FERV with RICE; obtaining the set of initial data for carrying out a calculation study for the standardized steady ESC test cycle and the 2Ch10.5/12 autotractor diesel engine, calculated assessment of the values of the complex fuel-ecological criterion taking into account thermal energy emissions in the environment during the exploitation of FERV with RICE. Problem of the study is the imperfection of existing methods for criteria-based assessment of the ES level of the exploitation of the PP with RICE, especially considering the realities of the functioning of the institutions and divisions of the SES of Ukraine and their FERV units in conditions of armed aggression and in the perspective of the post-war reconstruction of the critical infrastructure and economic of our country. Idea of the study is to improve the methodology for determining the values of the Kfe criterion by expanding the ES factors taken into account by its mathematical apparatus, in particular, emissions of thermal energy into environment. Main task of the study is determination of quantitative and qualitative aspects of the effect of taking into account the emission of thermal energy in the environment during a complex criteria-based assessment of the ES level of the exploitation process of such PP, in particular FERV units, using the steady standardized ESC test cycle (in accordance with UNECE Regulations No. 49) based on the improved mathematical apparatus of the complex fuel-ecological criterion. Object of the study is ES of the exploitation process of PP with RICE, in particular FERV units, taking into account the negative technogenic impact of thermal energy on environmental components. Subject of the study is contribution to the numerical values of the indicators of the object of the study of the emission of thermal energy into the environment. Scientific novelty of the results obtained is the method for taking into account the emission of thermal energy into the environment from PP with RICE, in particular FERV units, in a complex criteria-based assessment of the indicators of the ES level during their exploitation has been further developed. Practical value of the results obtained is the results obtained are suitable for providing a quantitative and qualitative assessment of the studied effects and developing on this basis technical solutions and organizational measures to reduce or eliminate them by developing an appropriate environmental protection technology with executive devices on the methodological basis of the ES management system.
