Energy cogeneration: a viable and assertive alternative for companies


Currently, the existing energy demand in Brazil is mostly supplied by the production of hydroelectric plants. In 2014, according to data from Aneel, the production of electricity from power plants reached 95%. But the search for energy sources and distributed generation are already adding new practices to the market. And the growing global demand for energy itself drives this scenario.

And in line with this idea, energy cogeneration has been gaining more space. The alternative is a solution that deserves everyone's attention. In this sense, companies and their engineers, who are attentive to these demands and postures, have been following even more this very prosperous sector.

Facing the energy crises, very present in the country, the need to diversify the energy matrix is immense. After all, the resources used may run out and the professionals capable of leveraging the production of lower cost and more eco-friendly solutions are quite necessary. But, after all, what is energy cogeneration?

Learn what is energy cogeneration

Energy cogeneration is the simultaneous production of thermal energy/heat and electrical energy from a primary source of chemical energy, which is fuel. The energy production and distribution model is efficient for internal or third party consumption.

Until the 1940s, the alternative was more common, but had been left aside. This is due to technological advances that suggest other experiments. Nevertheless, it remains a cheap, simple, safe, and environmentally friendly way. And, more than this: it is attractive because of the part of the energy, which is generated in the production of electricity from fossil fuels, such as that released in the form of heat, for example. Which can be harnessed for heating air, water, among other uses.

To have an idea, the European Union has defined for the year 2010 that 18% of electric energy would be produced by means of cogeneration. This is because the environmental impact is much reduced, making it an advantageous way of meeting the good practices stimulated by an awareness about the preservation of natural resources. In line with this, several countries have also been defining their internal goals and launching benefits such as the reduction of tariffs for the use of the electrical system.

Cogeneration alternatives

The growing, advanced technology at the service of people, as well as the needs of the market, provide many means of generating energy. With this in mind, ideas that guarantee the competitive content of the companies, without giving up efficiency, quality, and a conscious attitude are valued.

The main equipment that make up these systems are those that, using a fuel (biomass and/or natural gas) produce mechanical energy, to move a generator that produces electricity and, complementarily, other equipment produces thermal energy (heat and cold). But there are still others that can be related, such as:

  • combustion engines (Otto or Diesel cycle);
  • boilers that produce steam for steam turbines
  • natural gas turbines;
  • recovery boilers and heat exchangers;
  • electrical generators, transformers and associated electrical equipment;
  • absorption chiller systems, which use heat (steam or hot water) to produce cold (air conditioning);
  • combined cycle systems (steam turbines and natural gas) in the same plant;
  • equipment and control systems for generation and final use of energy.

Pressure Reducing Turbine: a solution

More than generating clean, efficient and low-cost energy, the idea of being able to do it in a way that also uses what would be wasted, further reducing this number, was Prosumir's motivation. The renewable energy generation and cogeneration company is part of this sustainable and intelligent movement, which uses technical knowledge to propose energy efficiency.

Thus, it created the Pressure Reducing Turbine (PRT), an idea to reduce waste in factories. The product is a solution that aims to replace reducing valves with microgeneration energy turbines. In other words, these are turbines that lower pressure and, instead of wasting heat, generate energy with it.

Through them it is possible to generate savings of 10% to 20% of the expenses with electric energy. This is in line with the conscious attitude of many initiatives and of an entire consuming, but also investing, community.

TRP proposes the reduction of costs with electric energy and the increase of energetic efficiency together with the reduction of the environmental impact. The Prosumir company aims to serve industries by providing a performance model with zero cost for the companies that will acquire it.

Meet Prosumir's Pressure Reducing Turbine and learn how it can generate energy efficiency for companies committed to sustainable practices and process optimization.
