摘要

本研究在对Parsadanov教授的燃油与环境综合判据值作为柴油机往复式内燃机发电厂开采过程生态安全水平指标进行计算评价的基础上,考虑到水库大小呼吸现象引起的发动机燃油蒸气的大量小时排放,提出了方法和方法。本研究的目的是开发一种方法,将污染物排放到环境中的参数,如发电厂燃料箱的大小呼吸现象所产生的汽车燃料蒸气,作为一个独立的生态安全因素考虑在内。根据该方法对发动机燃油特性、油箱加注程度、发动机运行模式特点、大气温度日差和油箱呼吸阀设置进行了计算评估。研究发现,考虑小呼吸现象引起的发动机燃油蒸气排放对环境安全水平几乎没有影响,但对于考虑大呼吸现象影响的选项,这样的影响是显著的。所得结果的科学新颖之处在于,首次在基于复杂准则的生态安全评价中考虑了往复式内燃机油箱大小呼吸引起的发动机燃油蒸气排放。所获得的结果的实用价值在于,它们适合于定量和定性地评估所研究的影响,并在此基础上制定技术解决方案和组织措施,以在环境安全管理体系的方法学基础上,包括使用其他稳定的标准化测试周期作为发动机运行模型,通过开发适当的带有执行机构的环境保护技术来减少或消除这些影响。

ACCOUNTING THE EMISSIONS OF ENGINE FUEL VAPORS IN THE CRITERIA-BASED ASSESSMENT OF THE ECOLOGICAL SAFETY LEVEL OF POWER PLANTS WITH RECIPROCATING ICE EXPLOITATION PROCESS
This study proposed the approach and method on its basis for carrying out of the calculated assessment of the values of the comprehensive fuel and environmental criterion of Prof. I. Parsadanov as the indicator of the ecological safety level of the exploitation process of power plants with diesel reciprocating internal combustion engine, considering the mass hourly emissions of engine fuel vapor caused by the phenomena of large and small breathing of reservoirs. The purpose of the study is to develop the method for taking into account the parameters of pollutant emis­sions into the environment, such as motor fuel vapors due to the phenomena of large and small breathing of the power plant fuel tanks, as an independent factor of ecological safety. The calculated assessment according to the proposed method is carried out considering the properties of engine fuel, degree of a fuel tank filling, features of model of the engine operation, daily difference of atmospheric air temperature and settings of the respiratory valve of the tank. It is found that considering the emission of engine fuel vapors caused by the phenomenon of small breathing has almost no effect on the level of environmental safety, but for the option of taking into account the effect of the phenomenon of large breathing, such an effect is significant. The scientific novelty of the obtained results is that for the first time a method for considering the emission of engine fuel vapors caused by large and small breathing of fuel tanks of reciprocating internal combustion engines in complex criteria-based assessment of ecologi­cal safety. The practical value of the obtained results is that they are suitable for quantitative and qualitative assess­ment of the studied effects and development on this basis of technical solutions and organizational measures to redu­ce or eliminate them by developing appropriate environmental protection technology with actuators on a me­thodological basis of environmental safety management system, including the use of other steady standardized testing cycles as models of engine operation.
