BACK PRESSURE TURBINE
EXTRACTION CONDENSING TURBINE
REHEAT CONDENSING TURBINE
◆ For small electrical output 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 output
◆ Tandem compound or Single cylinder
◆ Internal / external control extraction and non-controlled extraction applicable for process and feedwater heaters.

HIGH-RELIABILITY, HIGH-EFFICIENCY STEAM TURBINE
◆ Impulse design and inherently rugged compartment-type construction
◆ Compact shell-mounted control valve construction in high-pressure section
◆ High-pressure steam inlet construction◆ True center support construction of the
casing and nozzle diaphragms◆ Spring-backed shaft packing◆ Double-sheet spool-type extraction
control valves
◆ Solid rotor, flexible shaft construction◆ Tilting pad journal bearing◆ Tapered-land type thrust bearing◆ Horizontal split, casing, nozzle, and
packing construction◆ LP and HP EHC control system with
high control accuracy◆ Standard block design
