BACK PRESSURE TURBINE EXTRACTION CONDENSING TURBINE REHEAT CONDENSING TURBINE ◆ For small electrical

utput and large

thermal output ◆ Exhaust is applicable for process steam, district heating etc. ◆ Low initial cost without condenser ◆ Wide variety of electrical / thermal output combination to meet the demand of clients. ◆ One or plural internal pressure controlled extraction is applicable for process steam, district heating etc. ◆ External control and non- controlled extraction is also applicable for process and feedwater heaters. ◆ For larger electrical

utput

◆ Tandem compound or Single cylinder ◆ Internal / external control extraction and non- controlled extraction applicable for process and feedwater heaters.
