Air cooling island

Jieneng Group is committed to the application and market development of complete sets of technology for small and medium-sized air-cooled steam turbines and air-cooled islands, providing you with more environmentally friendly, efficient, energy-saving, and safe complete sets of turbine island systems.

 
◇The complete system of the island includes：Steam turbine (including exhaust device), air cooling island, shaft seal cooler, low-pressure heater, deaerator, high-pressure heater and other main and auxiliary equipment of the steam turbine, as well as the air cooling island system. Among them, GEA, an international air cooling spoiler, provides mature air cooling technology support and heat exchange components.
Compared to the traditional design model of separate machines and islands, the complete development of machines and islands has obvious advantages in the design, construction, commissioning, and operation of projects.
 
◇systems design
The complete design of the turbine island integrates the steam turbine system and the air cooling island as a whole, optimizing the air cooling unit system to achieve optimal performance.
⊙Traditional air cooling unit design mode：
Independent design of air-cooled island based on turbine exhaust parameters
Disadvantage: The overall efficiency of the air-cooled unit cannot reach its optimal level.
⊙Complete development model of machine island：

◇Excellent Quality 'Vertical Triangle' Air Cooling Island
Based on over 70 years of experience in GEA's air cooling island engineering, and tailored to the operational characteristics of small and medium-sized air cooling power plant projects, we have been applying and verifying our "vertical triangle" air cooling technology and services for many years, providing excellent cost-effectiveness to our customers.
The air heat exchange flow field is more reasonable, greatly improving its adaptability to environmental winds and avoiding the occurrence of 'heat reflux'.
The 'vertical triangle' abandons the conventional fan bridge and adopts a reinforced independent support structure, effectively solving the problem of fan vibration.
The 'vertical triangle' air-cooled island has lateral air intake, significantly lower structural center of gravity, and saves a lot of civil engineering costs.
‘The layout of the vertical triangular air-cooled island heat exchange unit is flexible, and the integrated arrangement of 'machine' and 'island' becomes easier to achieve.
‘The height reduction and standardized modular design structure of the vertical triangular air-cooled island heat exchange unit project make installation quick.
