The simplest technological schemes are given, a brief description of the devices and operation of the main equipment of thermal power plants (TPP) with steam (steam turbine), gas turbine and steam-gas plants. The main attention is paid to the layout features, architectural and construction solutions of the main buildings, auxiliary production systems and TPP facilities. The requirements for the TPP sites, the location of buildings and structures on the situational and general plans are listed. The corresponding diagrams are given. Structural features of the main housings in metal and reinforced concrete, solutions of assemblies, joints are considered. The issues of technical re-equipment, reconstruction of thermal power plants, main buildings with the installation of modern equipment were touched upon. Layouts of proposed solutions are presented. Fire safety issues are reflected.
