ZHM Huawu Steel has built the largest A-frame ACC fleet in the world.
 
Products:About A-Frame Roof Steel Structures for Air Cooled Condensers

The traditional A-Frame is a state-of-the-art air-cooled condenser (ACC). It’s suitable for small to large power plants in a large variety of conditions (low ambient temperature, high wind, high seism, low noise and many others).

ACCs immediately condense the steam turbine exhaust flow and return condensate to the boiler without water loss. The steam is directly condensed in air-cooled finned tubes without using an intermediate surface condenser.

Features of an Air Cooled Condenser

An air-cooled condenser (ACC) is made of modules arranged in parallel rows. Each module contains several fin tube bundles. An axial flow forced-draft fan located in each module, forces the cooling air through the heat exchange area of the fin tubes. An ACC installation consists of:

• a supporting structure
• a steam ducting from the steam turbine interface
• auxiliaries such as condensate and drain pumps
• condensate and duct drain tanks
• air evacuation units
• related piping works and instrumentation

Benefits

01-Sustainable The air-cooled condenser prevents unnecessary water usage from the condensing power cycle. The uniform steam distribution and total absence of backflow of steam, results in an increased performance and prevents air accumulation, flooding, sub-cooling and freezing.	02-Flexible Air-cooled condenser solutions are flexible in power plant site selection. Benefit of the flexibility in module arrangements tailored to the best usage of your available plot.
03-Cost efficient Benefit of a decreased lead time for plan permitting. The finned tubes from the air-cooled condenser have an excellent manual or semi-automatic cleaning system.	04-High quality ZHM Huawu Steel Dry Cooling air-cooled condenser solutions contains top quality single row condenser fin tubes. They offer an excellent corrosion and freezing resistance.

Modular Air Cooled Condenser Metal Works Module Air ACC is an innovative modular air-cooled condenser (ACC) that directly condenses steam turbine exhaust fow and return condensateto the boiler without any water loss. With construction savings of up to25%, compared to a standard A-frame, construction time can bereduced by several months for large power plants.
W-style Air Cooled Condenser Metal Works W-Style ACC is an innovative Induced Draft Air-Cooled Condenser(ACC) directly condensing the steam turbine exhaust fow. The condensate returns to the boiler without any water loss. With its unique "W" heat exchanger structure, the amount of steel and overall height of the ACC are dramatically reduced. This is useful for all powerplant applications.
Box Air ACC is an innovative Induced Draft Air-Cooled Condenser (ACC), suitable for all power plants ranging from 1 to 30 MWe. This ACC type consists of standard boxes that are easy to assemble and that offer a short delivery schedule and high reliability level. Box Air ACC is used in waste incineration plants, biomass, solar and geothermal power plants and is suited as a capacity increase of an existing power plant.
Hexagon Air Cooling is a standardised, modular air-cooled condenser (ACC) which is easy to build and robust in performance. lt is used in waste-to-energy, biomass, small size electrical power plants and industrial co-generation.Hexagon Air Cooling induced draft configuration saves up to1 5% fan power consumption.
An Indirect Dry Condensing system connects an Indirect Dry Cooling tower (lDCT) with a steam surface or jet condenser. lts tall concrete orsteel shell eliminates hot air recirculation. Indirect Dry Cooling solutions offer a reduced maintenance and are suited for largecapacity condensing units.
Air-Cooled Heat Exchangers (ACHE) are custom designed heavy-duty fin tube heat exchangers. They allow the direct cooling by air ofvarious process mediums.ACHEs are used in applications in manyindustries, such as power, chemical, ORC plant, Oil & Gas, steel andseveral other industries
