As the name suggests a Boiler Turbines Generator is made up of a boiler, a steam turbine and generator, and other auxiliary components. The boiler produces high-pressure, high-temperature steam. The steam turbine converts steam heat energy into mechanical energy. The mechanical energy is then converted into electric power by the generator.

Steam from the boiler enters the high-pressure cylinder of a condensing turbine and, after passing through it, returns to the boiler via an intermediate superheater in a boiler-turbine unit. The secondary superheated steam is fed into the turbine’s medium-pressure cylinder, then into the low-pressure cylinder and condenser. A pump removes the water from the condenser.
It then passes through low- and high-pressure feed-water heaters, as well as a deaerator, before entering the boiler.
The technological processes in a boiler-turbine unit are vastly different from those in a nonmodular power plant. In a boiler-turbine unit, the boiler and turbine both start up at the same time, allowing for a smooth increase in steam pressure and temperature, which improves the warmup conditions for the turbine and steam pipes.
