Air Cooled Condenser

Air Cooled Condenser Overview:

The Tipo is a well known manufacturer of a high quality range of Air Cooling Condenser which are high on demand in the market and they can be got customized by the clients as per their requirements. These products are made using advanced technology and they offer a high performance to the customers.

Air Cooled Condensers

They are easy to install and consume a very low amount of electricity. These products are very durable and offer a long lasting service life to the customers. Tipo Process cooling with air as cooling medium is used successfully in many industry branches.With steadily increasing costs for cooling water it also becomes more and more important in the power industry. At locations where cooling water is not available it is often the only possibility for the cooling of process streams.

In the power industry air cooled condensers (ACC) are used for the condensation of turbine exhaust steam. According the condition of the steam the condensation takes place under vacuum conditions. During that process the heat of condensation is transferred directly to the ambient air. The steam is distributed via a steam duct to the condenser. The condenser consists of the required number of heat exchanger bundles which are arranged on an A-frame construction.

Features Of  Air Cooled Condenser : –

The heat transfer surface is made up of steel tubes with aluminium fins. Each bundle has a condenser-part and an integrated reflux-part. This makes for a reliable condensation of the steam and removal of non-condensable. The cooling air is conveyed and distributed to the heat exchanger bundles with axial fans in forced draft installation. The required speed reduction from the drive motors to the fans is done with gearboxes.

For smooth operation under varying load conditions the fan speed adjusted with frequency converters according to the required process pressure on the steam side. For demanding load cases, e.g. very low flows of steam and sub-freezing temperatures, the integration of condenser- and reflux-part in the same bundle makes it possible to completely close off parts of the existing heat exchanger surface.

Around the A-frame arrangement of the bundles a wind-wall which is build over the complete height of the frame reduces the influence of wind and prevents air-recirculation. The required vacuum conditions inside the condenser are established with an evacuation unit which is designed according international standards.The condensate is drained to a condensate tank through collectors and the connecting pipe work. Condensate pumps convey the condenser water to the feed water tank or the water treatment unit.

Maintenance And Air Cooled Condenser : –

In operation, condenser coils get fouled up by dust, lint or grease from a dirty environment or nearby machinery in operation. An excessive fouling up of the condenser coils will raise the operating discharge pressure and may increase compressor power consumption by up to 30%. Simultaneously, there is a loss of cooling capacity, which means that the compressor has to run for longer periods to produce the same cooling. This results in higher energy consumption and lower compressor life.

There are several ways to effectively clean condenser coils. Coils which have only a light build-up of dirt, lint or grease may be cleaned by a brush, vacuum cleaner or compressed air. In case of heavier build-up, it may be necessary to use a mild detergent or cleaning solution. While cleaning, care should be taken to prevent deforming or damaging the condenser fins which might block airflow through the coil and compound the original problem.
