Condensing System

A steam condensing system is an engineered system that condenses turbine exhaust steam back into water while maintaining the required vacuum conditions. It helps improve turbine efficiency and allows the recovered condensate to be returned to the boiler cycle.

Exhaust steam from the turbine enters the surface condenser and comes into contact with tubes carrying cooling water. Heat is transferred from the steam to the cooling water, causing the steam to condense into water while maintaining vacuum conditions. The condensate can then be returned to the boiler cycle.

By condensing exhaust steam and maintaining a vacuum at the turbine exhaust, the system helps maintain favorable turbine operating conditions and supports efficient expansion of steam through the turbine.

Maintaining vacuum at the turbine exhaust is important for efficient steam condensation and turbine operation. Mazda's condensing systems integrate Steam Jet Air Ejector (SJAE) systems to remove non-condensable gases and help maintain vacuum integrity.

Non-condensable gases are gases that do not condense along with the steam. Their accumulation can affect condenser performance and vacuum conditions. Mazda's condensing systems can integrate multi-stage steam ejector vacuum systems to remove these gases.

Geothermal condensers are designed for steam conditions that can involve high non-condensable gas loads and corrosive environments. Mazda offers both conventional and geothermal condenser designs, with specialized venting and corrosion-resistant materials for demanding geothermal applications.

Material selection depends on the cooling water, steam characteristics, corrosion conditions, and site requirements. Mazda's condensing systems can incorporate materials including stainless steel, titanium, and duplex alloys for demanding applications.

Yes. Mazda's condensing systems are custom-designed for new or existing power plant layouts. Design considerations can include steam inlet arrangement, cooling-water conditions, condenser materials, vacuum requirements, and integration with auxiliary equipment.

Mazda's complete engineered packages can combine steam surface condensers, Steam Jet Air Ejector (SJAE) systems, gland steam condensers, feedwater heaters, oil coolers, and other auxiliaries to provide an integrated turbine condensing solution.

Mazda Limited designs and supplies complete steam condensing systems incorporating surface condensers and associated vacuum and auxiliary equipment. Its systems are designed according to Heat Exchange Institute (HEI) standards and ASME codes and can be engineered for conventional, geothermal, and other site-specific applications.
