Abstract

The problem of interconnection the principal characteristics of Earth climate, combustion process and fuel utilization efficiency has been considered. Atmospheric (free) air serving as an oxidizer in combustion processes is differed by inner availability the water vapor. Absolute content of water vapor is defined by an air temperature and its relative humidity. Humidity impact of atmospheric air on fuel principal heat engineering (power) characteristics has been investigated, namely regarding the theoretical combustion temperature, as well as of low and high combustion value. Reduction of each of mentioned characteristics by growth of air water vapor content has been proved. The thermodynamic analysis of dependence the efficiency of fuel utilization on combustion air parameters has been carried out by varying its temperature and humidity. It has been stated for the first time that an air preheating till 373 K ensuring monotonous enhancement of efficiency and fuel consumption reduction in case of dry combustion air causes the efficiency lowering in case of wet combustion air (oxidizer). Negative influence of combustion air humidification is increased by rise the air temperature and humidity – up to air saturation (dew point reach). Ten main climate zones are highly differed between themselves by temperature and moisture characteristics, thus changing an impact upon combustion process for fossil and alternative fuels. Evaluation of interconnection the climate features and combustion processes has been carried out basing upon energy efficiency and environmental consequences including analysis of greenhouse impact and input of greenhouse gases (CO2) into global warming the climate.
