Delivering 320 MW of power at 43% thermal efficiency in simple cycle operation, MST-70 steam turbine is designed for heavy-duty power generation applications. This machine incorporates two separate cylinders including HP-IP and LP sections. The steam enters the HP section via two throttle and eight governing valves. The steam is returned to the boiler afterwards to be re-heated to the HP inlet temperature. It is now ready to be entered into the IP section through two interceptor valves and from there to the LP section which includes double back-to-back sub-sections.
