How being more sustainable

With the change of century, the Spanish public institutions promoted the development and investigation of renewable energies.

Today an agenda could be established on its promotion: Some years ago they began with the wind power which continues its expansion gradually; it is nowadays continued with the promotion of the manufacture and consumption of bio-fuels, to which many companies are added by the incentives promised by the Spanish government. To finish, it seems that the solar energy is the great bargain now. On the other hand, Spanish companies are really well internationally positioned in reference to the treatment of the water and its operation.

As the main technology of our company is based on the thermal oil as heat transmission vehicle, we always advised to our clients that once the useful life of the oil is finished, this one be sent to recycling plants. In that way. they still valorize it for being used in very specific motors of electrical production plants.

The thermal oils, being of mineral or synthetic origin, they can not be used in the manufacture of bio-diesel as inform to us a manager of one of the main production plants at national level. Although its recovery is a very minority activity, it is a small step for the environmental sustainability that all the user companies of these oils can make.

Other oils, like vegetable for frying, they are used in the process of production of bio-diesel for the car industry, although the quantity of bio-fuel produced from them represents a very small percentage with respect to the rest of the production, which is based on oily plants.

From year 2007, the production of bio-fuels has been increased and the market has matured. Today, the industry is in a phase of debate on the efficiency of the different biomasses and applicable technologies.

We invited to you to visit the following link to the Directive 2009/28/CE, on requirements of sustainability and promotion of the use of renewable sources energy. Read More!

Study on our blog

We are proud to inform you about the study on new tools of communication for companies, made by staff of the Basque Country University  and titleholder “blog like communication and marketing tool”, in which blogs of 50 companies of diverse economic sectors have been analyzed, between which it is ours.

We hope that it is so useful to you as to us, as a consultation tool and like a vehicle to draw your own conclusions.

As we have already said few months ago, publishing our ideas and technology in a blog, it seemed to us from the beginning a good method to illustrate to own and other people's on a sector and product that sometimes seem distant, but they are not as much.

Please, remember: The technique moves the world, although always thanks to a few on it enthusiastic people. Read More!

Heat transmission fluids (2)

SMOKE or GASES. This source of heat is used generally when a surplus of energy in the form of smoke or hot gases exists.

In those cases, it is profitable to invest in a recovery unit or economizer that helps to reuse the heat that those smokes contain. Its design will be adjusted to the final application to which the residual heat will be destined. To do this, the recovery unit has coils, chambers, etc. through which water, air or any other fluid that it is interesting to warm up for other subsidiary process in the plant, will be forced to circulate.

Applications: Fuel saving by an industrial burner as a result of the preheating of the air used by it, for example, or, as a central heating or air conditioning of a plant, etc.

Water heating, steam production, etc.

The recovery systems are usually provided with a by-pass or diverter, to interrupt or to turn aside the smoke flow of its passage by the economizer or heat recovery unit.



THERMAL OIL. There are two types, synthetic and mineral, being different marks and models in the market, to work to different temperature ranks. We wrote about in a old post about the thermal fluid transmitters of heat.

The main characteristic of the oil is that it does not change of state when working over 100ºC under absolute pressure, reason why the circuit pressure that it generates it is not as high as the generated by other fluids.

We advise about the use of the thermal oil in processes in which it is needed indirect heat and high working temperatures (from 150 to 300 ºC).

Please remember that at the end of the useful life of the thermal oil, the user must recycle it, but about that we will speak in the next blogs. Read More!

New video about a boiler

I know that all you hope to read more on the heat transfer fluids but before continuing with that subject, I make this small interjection to inform to you that you already can see how it is our new electrical steam boiler, without having to move to our company:



We thank you for you visit in advance.

See you within fifteen days. Read More!

Heat transmission fluids

Following with the thematic developed in our last blogs of year 2009 and to start correctly the present new year, we will speak now about the heat transmission fluids, being the most common:

• Water
• Steam
• Smoke or stack gases
• Glycerin
• Thermal oil
  

WATER and STEAM. The water used in hot water boilers and steam ones (to produce this one) normally needs a previous treatment of decalcification, etc. to preserve the life of the boiler in which they are used, besides, sometimes, continuous purges of muds and foam that the process generates, which derives in energy losses. On the other hand, it usually is at the disposal of the users with facility and in abundance.

Basic characteristics: The water changes of state under atmospheric pressure at 100ºC, reason why if you wish to work with it over that temperature, you will have to increase the pressure, obtaining a product called High Pressure Hot Water.

Something similar it happens to the steam, with a result of the pressure-temperature saturation curve of steam (as example: 150ºC 5 bar a), obtaining in this case High Pressure Steam.

The design of the boilers can be PIROTUBULAR or ACQUATUBULAR, based on what is circulating through the tubes: if there are smokes or water.

In our next blog we will speak about the rest of heat transfer fluids. Read More!
