Used Howden 7 MW Twin Condensing Steam Turbine Generator – Siemens SST-110, 8750 kVA

Manufacturer:
Howden / Siemens Turbomachinery Equipment / TD Power Systems

Description:
For sale: Used Howden 7 MW Twin Condensing Steam Turbine Generator Set, Model Twin-CA 56, part of the Siemens SST-110 series, offering a reliable 7.0 MW power output. Designed for industrial steam applications, it operates on superheated steam at 900°F and 800 psi, with a main steam temperature of 445°C (833°F). The system also supplies plant process steam at 375°F and 46 psi, making it ideal for cogeneration (CHP) applications.

The unit is paired with a brushless AC generator featuring an AC exciter and rotating rectifier, built to NEMA MG-1 standards. With a continuous rated output of 7000 kW / 8750 kVA at 1800 RPM, the generator features a cylindrical rotor, IP54 enclosure, and IC 81W cooling for robust and efficient operation in industrial environments.
