Accessories

Following the recommended maintenance plan for turbines extends service life and significantly improves reliability and efficiency. The scope of planned repairs depends on the operating hours of a turbine. Modernisation increases performance and reliability of stream turbines – and speeds up return on investment.

Beside the feed water heaters and condensers Doosan Škoda Power can also design accessories that are necessary for heater/condenser operation. Furthermore, we can design other heat exchangers, water-water type or steam-water type.

Design according to EN standards, ASME code, AD Merkblatt, HEI Standard, TEMA Standard

Main steam jet air ejectors (MSJAE), starting ejectors

Steam jet air ejectors are used for extraction of non-condensables out of condenser. They help maintain the vacuum inside the condenser.
Starting ejector is used to quickly evacuate the condenser and turbine at the start-up.

Water jet air ejectors (WJAE)

Water jet air ejectors are used for extraction of non-condensables out of the condenser. They help maintain the vacuum inside the condenser.

Vent steam condenser

Majority of last stage vent steam from gland sealings condense inside VSC. Rest of the steam-air mixture is lead out of VSC via fans.

Gland steam condenser

If back-pressure turbine is required and there is no other heater where gland steam could be taken, gland steam condenser is used.

Combined vent steam and gland steam condenser

For back-pressure turbines combined VSCGSC can fully replace the separate arrangement. Suction in VSC is created using steam jet air ejector, extracting the steam-air mixture out of VSC.

Flash tanks, feed water tanks and other tanks

Flash tanks are used for separating the liquid and steam phases after the pressure drop.
Tanks
Tanks without deaerator
Demi water reserve tank, condensate tank, etc.
