TAKING INTO ACCOUNT THE EMISSIONS OF CO2 AS A TOXIC POLLUTANT AND AS A GREENHOUSE GAS IN FUEL AND ECOLOGICAL COMPLEX CRITERIA-BASED ASSESSMENT OF DIESEL-GENERATOR OPERATION PROCESS

Abstract

In this study analyzed the types and features of the known models of exploitation of reciprocating ICE as part of the electric generating power plant, among which the stationary standardized test cycle D2 according to ISO 8178-4: 2017 is selected. A set of initial data is obtained for the calculated criteria-based assessment of the ecological safety level of the exploitation process of power plants with a reciprocating ICE at an example of the autotractor diesel engine 2Ch10.5/12 based on the results of processing of bench motor tests data. The mathematical apparatus of the complex fuel and ecological criterion of prof. I.V. Parsadanov. The calculation methodica for assessment of the values of this criterion has been improved by taking into account the mass hourly emissions of carbon dioxide with the exhaust gases flow from the reciprocating ICE both as pollutant and as greenhouse gas. The calculated assessment of the values of specified criterion was carried out with taking into account carbon dioxide emissions. It has been detected that despite the high values of the hourly mass emission of carbon dioxide as a toxic pollutant, taking it into account when criteria-based assessment in average reduces the value of the complex fuel and ecological criterion by 0.164 %, which is due to the small magnitude of dimensionless relative aggressiveness index of this pollutant. Accounting for the emission of such pollutants as greenhouse gas showed that such a contribution is 0.003 %, and in total, taking into account both aspects of the emission reduces the value of the criterion by 0.167 %. The dependences of the values of the criterion and its changes on the value of the greenhouse coefficient are obtained.
