STEAM TURBINE SST 150

SST-150 Steam Turbine (up to 20 MW)
The SST-150 is a single-casing steam turbine, proving geared drive to a 1,000 or 1,800 rpm generator respectively geared or drive for industrial applications.
The turbine is packaged in a skid-mounted design. For power generation, it provides high efficiency together with a compact arrangement.
It represents a solution based on long experience of industrial and covers the following applications:

Generator drive

>Industrial power plants and paper mills, sugar industry, textile industry, steel works and mines
>Cogeneration and district heating, combined cycle plants
>Waste to energy, e.g. waste incinerators; utilization of waste heat from chemical processes
>Petrochemical, refineries and FPSO (Floating Production, Storage and Offloading) applications

Key data:

>Power output uo to 20 MW
>Inlet pressure up to 103 bar / 1,495 psi
>Inlet steam temperature up to 505°C / 940°F
>Rotational speed up to 13,300 rpm

Design Concept
SST-150



>Single-casing turbine
>Back-pressure / condensing type
>Modular package unit design; pre-engineered turbine modules, modular peripherals
>Single controlled extraction
>Radial ehaust; exhaust flange with top or bottom exhaust
>Steam-driven emergency stop valve
>Separated oil and steam piping


The SST-150 single-casing, modular package design allows a wide variety of configurations to satisfy industrial needs in the most economical way. SST-150 turbine variations are achived by selecting from a number of pre-defined stages for incorporation into the standard design.
The utilitzation of selected proven components asures high reliability and easy maintenace. For generator drive, gearbox combined with generator is preferred, since this provides high efficieny together with a very compact arrangement.

Scope of supply
Each of the industrial steam turbines is available as a freestanding machine or as a package which includes generator (or other driven machine), gearbox, and all other auxiliary systems, normally mounted on a base frame. We can deliver each of our machines with the configuration that fits best to your needs.
