Loviisa gets new cooling towers

In the heart of Finland, the Loviisa witnessed the completion of the new air cooling systems. Although, the backup system is already present in the cooling of the sea water in Loviisa. However, they evolved the technology and built a modern and state of the art air cooling system for the enhancement of the plant. The new system will ensure the safety of the water as well and can be utilized and put to work in certain extreme situations when the plant’s reactors will not be cooled down by the sea water alone.

cooling towers

The heat exchangers are the new addition and the towers are situated in three separate buildings. According to the reports, the buildings do not have any significant impact and value on the plant area landscape. The height of the buildings is approximately 15 meters and they are 10 meters wide. There are two units of the Loviisa and a tower has been built for every unit. The purpose of the first tower is to eliminate the decay and clean the reactor while the second tower will also remove the heat from the fuel storage pools that have already been used and the tower will also be cooling the other equipments.

The towers are supplied by an engineering company in Hungary and are designed by Fortum. The towers get their power supply from plant reserve systems. The towers have been completed in terms of construction and the installation of machinery but they are yet to be made operational. The final testing of these towers is due later this year.

The towers use the sea water, which is approximately 40 cubic meters per second, for the cooling of the steam which regulates the electricity generating turbines. And the same water that was cooled down goes back to the sea after getting about 10 degrees centigrade warmer, with the rest of its properties still intact.

The nuclear reactors in the heat exchangers also need cooling when they are not functional. This will eliminate the heat that is being generated by the decaying of the radioactivity. Because of this reason, the emergency cooling system is enabled in all the nuclear plants to ensure the cooling systems are working properly even when the primary system fails to do so. In case of the loss and scarcity of the sea water, the Loviisa plant has a very well maintained back-up system. Moreover the construction of the new towers will further ensure the plant’s safety in the future as well.

There are many air cooling systems which are working remarkably, but the new cooling towers in Loviisa are one of the best and also the first of its kind in the world, and a great nuclear power plant. These towers are also the finest and very cost effective when it comes to the safety and the cooling of sea water. The towers will be operational after its testing by the concerned authorities later in 2015.

The Global Industry Analysts releases a new report about heat exchangers

Engineering industry analysts

The heat exchanger market globally is soaring high. It is expected that by the year 2020, the market will rise up to USD 24.3 billions, which is a new high. And this expected rise in the global market is said to be because of the new innovations in heat exchangers for energy efficiency.

Heat exchangers are certain devices that are now technically used in most of the commercial, industrial and engineering units and applications. Be it automotive, manufacturing, aerospace or the commercial aspects, the heat exchangers are now essential for the energy consumption and its utilization. With the increase in the number of factories and industrial units, the demand of heat exchangers has certainly gone up in the recent years.


More and more companies are adapting the easy method of energy saving and consumption through the heat exchangers. As the world is still progressing in terms of innovation and technology, the demands of heat exchangers are said to be going too high in the coming years. The heat exchangers have made the energy consumption easier for them and they are also very cost effective and durable in the long run.

The sector, which is going to see the highest heat exchanger growth is the nuclear power sector. The growth in the future will also be encouraged by the continually growing emphasis on cost effectiveness, and the energy saving. The climate, fossil fuel resources, green energy and environmental pollution are some of the major reasons that are helping in shifting the global focus towards the heat exchangers.

As the new report says, the Europe is going to dominate the heat exchange market in the world. The Asia Pacific is also emerging to be the largest growing market and also the fastest on the regional front. It has a CARG of 8.9%, which is relatively higher than the other market sections of the world. There are multiple factors for this such as an increase in the income level, industrializations, favorable demographics, fast urbanization, and the infrastructure development by the government and civil society.

The report also provides an extensive research on the heat exchanger market globally in different parts of the world. The report, based on the latest findings also predicts the future growth of the heat exchangers market. It also specifies the area where the growth is expected to be much higher than the others.

There is no denying in the popularity growth of the heat exchangers over the last few years and they are more likely to grow speedily in the future also. Many industries and factories are now resorting to this new development in the field of technology because it is affordable and cost effective. These heat exchangers minimize the labor work and also produce faster results. If the global industry analyst report is to be believed, then the heat exchangers will take over the industrial market soon, with the European region leading the market over other regions of the world.

How does a heat exchanger work?

info advice guidance

Energy saving is a big problem for many of the factory owners and it also robs them a lot of money out of their pockets. Therefore, the factory and workshop owners are now looking for energy saving substitutes and are installing the heat exchangers.

These heat exchangers help a lot in terms of energy saving and consumption and also make the most out of the other waste gases. Many electronic devices, irrespective of their size, are using heat exchangers like car engines, planes, air- conditioners, ships, refrigerators etc. They eliminate the heat and convert it into the cool air and supply it back to the devices and equipments.

how does heat exchanger works

What are heat exchangers?

They are a type of devices that let the heat from one fluid to pass on to another. In the whole procedure, the heat exchangers do not let both the fluids to come to direct contact or to mix with each other. These heat exchangers are used in many different types of machinery, as their main purpose is to exchange the heat with the cool air. The heat exchangers are going to be a new trend setter in the coming years because of the rapid increase in their demand all over the world. The global industry analyst has already predicted the future of heat exchangers and their growing demand in the industry and the urban revolution of the world.


Different kinds of heat exchangers:

Most of the heat exchangers, more or less do the same work, and that is to convert the heat from one fluid to the other fluid. The working ways of these heat exchangers could be different from one another. The two famous types of heat exchangers are plate/fin and the other is the shell and tube. They both work differently and have different methods, but serve only the same purpose and that is exchanging the heat and converting, and making use of it according to the advantage.

Plate Heat Exchanger Working Principle

Uses of the heat exchangers:

They have many uses but most of the time you will find them helping or working with the machines and engines, so that they can perform more efficiently. With the air conditioners and refrigerators, it is the other way around, the heat exchangers absorb the heat and remove them from a selective area or place where it is unwanted, and throw it away to other places.

In the buses, the heat exchangers are used to cool down the engines. The car radiator can also be a type of heat exchanger. The water goes through the radiator to cool down the engine, and when the car starts to drive, the cold air near the radiator eliminates the heat from the air, and keeps the engine to perform effectively and increases its life.

A heat exchanger can also be installed in a shower. The cold water picks up some of the heat from dripping water. The cold water is converted into the cold water through a process.
