The back pressure turbine is used for supplying process steam to the facilities of private-use power producers. This type of steam turbine supplies not only electricity but also steam to various process requirements.
Back pressure turbines can either be single stage or multi-stage, which are often used in industrial plants. The turbine serves as a reducing station between the boiler and the process steam header.
In an uncontrolled extraction type, a tap is provided at a predetermined stage for drawing out the steam for heating solutions.
The uncontrolled extraction Process steam is used for process steam applications (with a smaller quantity of steam flow and set temperature requirements) and LP heating applications like de-aerator for heating solutions.
