Our researches

The need to achieve ambitious goals like a major environmental sustainability and an important energy saving has led us to create the section Development & Research. Here we study, we plan and we test the best solutions that can give more environmental sustainability and great saving. We’ve got several projects in the pipeline, that are constantly evolving!

Speaking: about biomasses…

We’re sure that what we’re working on, will offer very soon great advantages! This is the product obtained by the fragmentation of plant materials in " flakes " or "chips " . This material is very heterogeneous and becomes useful for the production of energy at low cost. He manages to keep costs to a minimum heat output of the order of 1/3 and 1/8 to over fossil fuel normally used .

This is an heterogeneous material so we have to consider both the characteristics of its vegetable essence, its humidity and its size. The knowledge of the product is very essential, to make proper assessments about the use of this product.

Source tables illustrate with great precision the calorific value and the weight “for the poured volume” of the material in relation to its humidity, these are key factors if we consider that woodchips is paid by weights but users take advantage from its thermal value, so a wet product weights much more and heats less!


Why:

The thoughtless use of fossil fuels is very common and well known, and at the same time is the fastest, most efficient, and organized method to damage our existence. Just think of the prospect of depletion of the world’s oil and gas resources leading to scarcity of supply and the increase of greenhouse gas emissions that the Kyoto Protocol is struggling to constrain. Finding a substitute to these fuels, together with rapid renewability, low impact on environment, at lower costs, it’s like a miracle!

Back to reality we call say that there is a solution for a certain need of energy, that is cheap, biocompatible, offering great advantages.

A fact: considering the present situation of the forestry resources in our country, we can notice that there’s a compelling need to be constantly regenerated. According to the last figures from appointed bodies and authoritative sources, the 80% of this heritage is facing this problem.

If we stimulate market demand for woodchips, we will bring profitability to clear-felling and the following reforestation, starting a real regeneration of woods and national forests, with a new force and the a better capacity to improve biochemical exchange and sorption for the transformation/reduction of carbon dioxide emitted from the life processes. This will bring benefits to the whole society:

In the future: wise and correct use of renewable fuels and reduction of level of carbon dioxid coming from polluting fossil fuels and bad use of the outdated plants.
In the medium term: involving new activities and creating employment.
In the long term: possibility to develop a strategy for the regeneration of the environmental heritage, and consequently a better air quality

Woodchips: how and when?

How:

How can a fuel be used without burning it?

A good question to ask… The important thing is to do it correctly and optimizing the performance! What just mentioned is not common place! The ligneous material during the combustion, produces the famous “dioxins”, groups of compounds that even if so different from each other they’re so close for the consequences on our health. The percentages produced given of our stoves or fireplaces, don’t seem a problem in accordance to our beliefs and convictions, but even in these situation quantities play an important role and surely these factors should be considered.

There’s a solution: the use of fuel together with the support of suitable systems, expressly conceived for this service, under controlled temperate and supply, to limit the harmful effects and to improve performances.

The evolving technology, has developed some important new way of using woody biomass, improving its usability. (Production systems for local nets of Syngas-district heating)


When choosing this solution?:

Then can be several possibilities, but each one has to be analyzed with the support of specific studies and researches.

Thanks to our consolidated experience, we can provide consultancy and assistance from the feasibility studies, design and supply to the installation of the systems and their maintenance. In the next paragraph some considerations about the wood cogeneration system.

Use: Generation - Cogeneration

The generation from woody biomass:

Un impianto di generazione da biomassa legnosa presenta qualche differenza dagli impianti termici convenzionali (ovvero a Gas o Gasolio). Dimensioni dell'unità, spazi complementari e di servizio necessari e smaltimenti hanno caratteristiche da tener bene in considerazione.

La biomassa legnosa (con umidità di circa il 30 %) ha P.C.I. pari a circa 1/3 del gasolio a parità di peso, contro un volume decisamente più grande e si presenta come scaglie irregolari per dimensione e peso. Come conseguenza il generatore in se ha dimensioni più importanti di un pari potenza convenzionale, i sistemi di gestione e carico dell'alimentazione sono quindi a loro volta più ingombranti e complessi.

Approvvigionamento, stoccaggio e movimentazione necessitano di infrastrutture e spazi di servizio da tener ben presenti durante le fasi di approccio a tale filosofia. Il legno inoltre è un materiale “vivo” e questo deve far prevedere sistemi di mantenimento ottimale anche durante il periodo di semplice stoccaggio.

The cogeneration from woody biomass:

The term “cogeneration” refers to the simultaneous generation of energy through different forms (thermal, electrical, mechanical …) starting from one single process and one single source. Cogeneration systems come from the consumption of fossil fuels too, and like for the generation systems, they have optimized characteristics and sizes. The use of woody biomasses undergoes the same standards mentioned above.

It’s important to focus on the easy interpretation of the convenience of cogeneration in wider terms (not only from biomasses). For sure, optimizing cogenerative production means sparing quantities of fuels, but in some cases the requests for cogeneration plants are too unbalanced and don’t meet the real technological potential.

Most of people are attracted to the topic of renewable fuels, thinking that everything is possible or rather it’s convenient. Cogeneration is, as already said, a contemporary generation, mostly of thermal energy and electrical energy ( when is not used on site) is provided to the distribution network.

Electrical energy has the disadvantage of accumulation, but on the other side has the advantage to be transferred to the national network (travelling at the speed of 300.00 km per second) making it available everywhere and giving always advantages.

On the other side, the thermal component, when is not used at the same time, could give some problems with the transfer, and even if it can be accumulated in large amounts (with significant room needed and relevant costs) but for a short time. Imposing works for infrastructures, costs, leakage are some of the facts to take into account. These conditions require a consideration of the cogeneration plants according to different variants and standards.

Although it is the amount of electricity that most attracts the attention of those who want a cogeneration is actually the heat demand in all its features and components that allows to evaluate the convenience of a plant.

 The analysis of the " Profile of Annual Thermal Needs" of the user is therefore the first and mandatory step in the evaluation of the feasibility and convenience of a cogeneration plant.

Productions: Study - Development

Study:

In addition to the installation of various types of systems for power, size, we applied technology and innovative solutions we have our pride; our CHP evolved in its entirety and that in addition to producing energy for the needs business is set up with instruments, controls, gauges, probes and analyzers that allow us to test on site in addition to standardized operations also forced operations or particular types of biomass, waste or residues from special operations and anticipate and provide for corrective measures to remedy any anomalies found in these tests.


Development:

This allows us to design new plants minimizing the possibility of malfunctions, defects, of hazardous waste or unwanted or unwelcome problems even at the conclusion of a project; by presenting already quote the view of the procedures provided for the overall maintenance of the system, its operating costs, the resources needed and the preparation of the subjects that you will operate.

New frontiers: Experimentation Research - Ideas: environmental recovery!

The experimentation:

New technologies, new products, new solutions. To verify the validity, efficiency, convenience must always be experienced! Laboratory tests and pilot plants provide us with the experience and the knowledge to decide whether and when to adopt new solutions, providing our customers the effectiveness of our proposals.

Research:

The urge to always look for the best solutions, test new technologies and an innate curiosity leads us to have in the internal R & D engine that will allow us to overcome more and more ambitious goals. Some ideas are already in phase of experimentation and development (for example, a domestic apparatus for the gasification), others still in the incubation...

Recovery sites severely compromised by forms of pollution very dangerous to health.

Our research

A valid partner for the ambitious goals of increasing environmental sustainability and an important energy saving us, we feel compelled to structure the section of Research & Development.

Here they study, we build and test solutions that offer big savings and enhanced bio-sustainability. Projects in the pipeline are obviously different and constantly changing!

The Gasification

What is

La gassificazione è un processo noto fin dall’Ottocento



Gasification has been around for decades, at least from the nineteenth century, at first just used ad “town gas” then replaced by methane and electric power. Gasification became more popular during the wars, for tractions, because the traditional fuel was hardly available.

The gasification process converts biomass into a mixture of synthetic gases (“syngas”) that are used for burners, otto cycle engine and turbine etc. The core of the gasification system is the gasifier, a thermo-chemical reactor where there are reactions at high temperatures from 700 to 1200 °C.
