Electric Heat Tracing Technical Solution for Thermal Power Combined Plant is mainly designed for freeze protection for pipelines, tanks, instrumentations etc for the thermal power plant. The principle used to build Combined-cycle Thermal Power Stations consists in an arrangement of heat engines working together from the same source of heat, turning it into mechanical energy that drives electrical generation.
