An Improved Approach to Evaluation of the Efficiency of Energy Saving Measures Based on the Indicator of Products Total Energy Intensity

Abstract

Existing methodological approaches to determining the total energy intensity of products and its components are presented. The methodological approach to determining the direct (technological) energy intensity of products on the example of combined production of energy at Combined Heat and Power (CHP) plants with the allocation of energy costs for certain stages of the technological process is improved: preparation of fuel, its submission to burners, burning in a boiler plant and the implementation of natural resources. This detailing of energy costs makes it possible to compare options for upgrading power equipment across all power plant workshops. Two types of CHP plant are considered: coal and gas, appropriate equipment structure, technologies that can be implemented to replace existing, less efficient ones. Three variants of possible modernization of the CHP plant on coal fuel and two—on natural gas are presented. The technological potential of energy saving in the case of implementation of the modern technologies for the production of energy at the coal CHP plant as more environmentally hazardous has been calculated, provided that the environmental requirements and the implementation of environmental measures are achieved. Effective technologies for reducing emissions of nitrogen oxides, sulfur oxides and particulates have been considered as environmental measures.
