The extraction condensing turbine is able to change the electric power and the process steam flow independently by adjusting inlet steam flow and process steam flow. Adjustment of process steam flow is implemented by the extraction control valve. The turbine output is adjusted by the main control valve for inlet steam flow in conjunction with the LP turbine […]

There are still a large number of back-pressure turbines in district heating schemes in eastern Europe and the CIS. Many of these are now being or have been replaced by combined-cycle plants with condensing–extraction turbines. Some of the first installations were in East Germany and Hungary. With this arrangement, all the steam can be applied […]
