• Thermal Energy, Semester 2, position 2

Getting to know the procedures for the selection of the type, parameters and configuration of the thermal power plant according to demand of energy consumption, available sources of primary energy, energy and economic performances and other important criteria. Also, learning on the performance and technological characteristics of individual technological systems in thermal power plants. Exercise program is based on the implementation of certain practical knowledge of the course program by solving of specific examples.

On completion of this course, it is expected that student will be able to: • identify different technological subsystems within the thermal power plant, • projects technological scheme of thermal power plants with steam and gas turbines, • conduct techno-economic analysis of the operation of thermal power plants, calculate the production price electricity and determine the economic feasibility parameters, • calculate and optimize the condenser plant, • determine the necessary flow of cooling water, • perform calculation and optimization of feed water heater.

The influence of the main factors and criteria for the selection of the thermal power plant. The structure and characteristics of the final energy consumption. The choice of configuration and parameters of the thermal power plants: basic and main thermodynamic parameters for steam and gas power plants, thermodynamic improvements of steam and gas turbine power plants. Estimation of the cost of electrical energy production and the optimization criteria of the thermal power plants: the total costs of energy production, comparative cost factors as optimization criteria and indicators of economic viability. Power plant and a complex technological system. Technological scheme of thermal power plants. Technological scheme of the main system for the production of electricity that includes the start and stop function block. Other systems: fuel supply, drainage, transportation and disposal of ash and slag, condensation plant with a system for supplying cooling water, system for the control and management of steam plants.

Visits to power plant are planned to learn about the major technological power generation systems (steam turbine plant and boiler house) with the main auxiliary technological systems. Foresees a Three tasks related to the calculation of production costs and prices of unit of electricity, design of technological scheme of the main power plant cycle and the application of economic parameters to optimize the thermal power plant. Test of students knowledge is planned by 3 tests in theoretical fields, examination and evaluation of calculation tasks and report on the visit to power plant.

Passed exams in Thermodynamics and Fluid mechanics.
