Abstract
Technical thermodynamics is very important in the education of engineering staff, especially in the
education of mechanical, electrical and civil engineers. Technical thermodynamics as a scientific
discipline was developed for the purpose of solving important technical problems significant to
engineering professions. These problems cover a wide area starting with production and optimal use
of thermal energy. Optimal use of thermal energy in thermal processes has always been the goal of
engineers, and this is especially important today when our planet is facing noticeable thermal
warming, and consequently climate change. Fossil fuel combustion was used as a heat source in the
development of all industrial processes, resulting in the release of unwanted greenhouse gases into
the atmosphere, predominantly CO2, which was reflected in a significant increase of the planet Earth’s
temperature. When using fossil fuels, other side effects occur, such as the presence of nitrogen oxides
NOx as well as other constituents in the atmosphere. Therefore, thermal engineers today are faced
with a strong demand for the optimal use of already produced thermal energy. One of the common
tasks before them is the requirement of waste heat recovery in thermal power plants. Usually, waste
heat is being used in cases such as: cogeneration processes, processes for the production of
technological steam, heating in residential buildings or food production facilities (greenhouses). Within
this paper, the waste heat recovery from one gas turbine is quantified. For the purpose of further
analysis, the benefits of using gas turbine waste heat are considered, used for preheating of the air
required for gaseous fuels combustion
