pyrolysis (or pyroscission) is a process of thermochemical decomposition of organic materials, obtained through the application of heat and in complete absence of an oxidizing agent (normally oxygen).[1] In practice while heating the material in the presence of oxygen occurs a combustion that generates heat and produces oxidized gaseous compounds, instead making the same heating in conditions of total absence of oxygen the material undergoes the split of the chemical bonds originating with formation of simpler molecules. the heat provided in the pyrolysis process is therefore used to dissolve chemical bonds, activating what is termed thermally induced homolysis. source wikipedia.
the precursor of this process in Italy is nat mulcahy American engineer, and inventor of the "lucia stove". that system, visible on many sites, gasification almost all types of biomass having humidity, residual less than 30%. the gas obtained for pyrolysis has thermal potentials equal to gpl, and the result of gasification and 'biochar, fundamental for the atmosphere "
This process, if continuous with appropriate procedures, can become an almost inexhaustible source of thermal energy.
Every day immense quantities of biomass waste are destroyed with considerable expenditure on collectivity and environment.
the possibility of self-producing energy at a cost close to zero fascinates me.
I then began studying a system that produces continuous thermal energy through pyrolysis, using various types of biomass waste.
My aim is to make the classic country farm thermally autonomous, which results in considerable biomass waste processing.
the study is at the beginning, so suggestions, and/or collaborations aimed at its development are welcome.

I am also studying some things in this sense, as I was made a fairly unusual request for us ... a little more logical if applied to other contexts.
it is about thinking of a system that revenues electricity from the combustion of the wood.
the roads to go, if we exclude the cabbages, are few.
or you think of an ironing engine that by means of heat can operate an alternator or you think of a steam system by means of which to operate a turbine.
we accept advice and criticism

As I said before, my study is aimed at the exploitation of the thermal energy produced with pyrolysis, I have no detailed five other uses of syngas. For those few knowledge I have of the industry, I could tell you that a turbine drive could be less expensive and more reliable.
a question, how do you plan to use a pyrolysis system?

Yes, given the low costs of such a system, it would have a lot of advantages for environmental impact.
the turbine system is definitely more efficient than an ironling engine but ... there is always a but.
imagine in africa that you have to install microplants for electrical production.
and imagine that to operate a turbine you will have to predict a boiler for the production of steam with all the safety systems of the case.
a system like that on a 1 kw plant (we don't do anything but in africa light 10 houses) I think it would be too expensive ... more expensive than a solar energy system.

the photovoltaic system according to the local authorities is not entirely recommended, as in the period of great rains .... you can have months of poor lighting.

no,no producing 1kw you will not be able to shock the system, the game probably does not apply the candle.
the existing plants, of much more consistent sizes, still have very high problems and costs.
I prefer to fly low, try to produce pyrolysis in continuous energy, it already seems to me a remarkable step, it's a challenge that fascinates me and that could prove to be of considerable profit. Don't you think?

the precursor of this process in Italy is nat mulcahy American engineer, and inventor of the "lucia stove".

I don't think the American invented something really new. by curiosity I went to check on wikipedia, and in fact I realize that you can get the idea of a last generation process.

Alchemists already observed that by warming the wood, an intense smoke was poured out from particular propitiancies, they called it "the spirit of wood" or "wood spirit", followed "pirolegnose liquor", "wood vinegar", and more recently "pirolegnose acid".
when it was studied a little more methodically (about the times of lavoisier) we realized that the wood is divided into four states, the first is the carbon residue, while the pyrolegnose liqueur is uncomplicable in three other states, a heavy and viscous with the cathorous aspect (heavy oils), a liquid and more volatile and an uncondensable and gaseous.

the process of pyrolysis has always been useful for obtaining substances such as plant tar, acetone, acetic acid and metilic alcohol, etc. with convoy gas they could produce well localized and persistent flames. at the time of the industrial revolution to produce fuel gas, it proved more useful to put mineral coal rather than wood to pyrolysis, thus the distribution spread through gas connections for public use (road lanterns) and private (ovens and stoves). Unfortunately it was very dangerous because it was a gas rich in carbon monoxide. in the future, if oil becomes increasingly difficult to extract and expensive, biomass pyrolysis products could be useful to supply monomers for the production of certain types of plastics.

As regards thermodynamic yield, I do not think that pyrolysis is greater than the thermodynamic yield of direct combustion, the true advantage of pyrolysis lies in the separation of fuels in compounds that can be used separately from different users.
so, for a simple boiler for heat production purposes it could be more convenient direct combustion of wood mass or biomass.

I'm sorry for the prolixsaggine. I've been trying to write today.

I don't have much time to stretch, so my answers will be quite telegraphic.
biomass gasification is as old as the world, my grandfather also produced coal using the venturi effect, but he did not know.
the benefits of the nat concern the fact that it has made this process accessible and familiar.
Similarly to fuel, the calorific power of pyrolysis is considerably higher than direct combustion, thanks to the higher temperatures reached by the combustion gas.
no direct combustion boiler can match a pyrolysis system, there are several treaties in this regard.
not least carbon segregation, biochar produced, and kyoto protocol.
Say hi.

 

[PaoloColombani]

Similarly to fuel, the calorific power of pyrolysis is considerably higher than direct combustion, thanks to the higher temperatures reached by the combustion gas.

hi, just as a discussion, I don't think it's possible to achieve a higher calorific power than fuel parity, otherwise we would have found a way to break the second principle of thermodynamics. the enthalpies in play are the same, moreover in the pyrolysis we must add possible losses for the process besides the fact that the carbon residue (coal) does not participate in the combustion, losing the total amount of heat to the user should be lower.

however you are right because the heat at low temperature is less "expensable"; especially if we talk about transformation into electricity, whether it is thermoelectric effect, or whether it is thermodynamic cycle, the final performance of the transformation is as much higher as the temperature difference of the two heat tanks is.

everything was meant as a return, but I saw you came by yourself.
the right observation of the carbon residue (biochar) that does not participate in combustion, but despite this the efficiency of fuel equal is higher (carnot teaches).
I see you're doing a fundamental thing about the process. I'm referring to the segregation of co2 in biochar.

 

[PaoloColombani]

I see you're doing a fundamental thing about the process. I'm referring to the segregation of co2 in biochar.

Well, that's not why I was just limited to "physical" considerations. It seems clear to me that carbon residue is a subtraction of carbon dioxide from the atmosphere, and this is a point in favor of pyrolysis.

does not subtract it, simply does not reimpose in atmosphere the carbon dioxide accumulated by biomass.
and given the environmental situation............ .

very interesting the process you described, could you give more information to be able to realize it?

[Mr.Rio]

I was reading a system of refining urban waste that allowed a dust to be obtained by pyrolysis of the fuel. the system was called thor and was developed by the cnr and a private company. . He seemed to be able to solve the problems of unloading of landfills but he did not hear much about it. something is found on wikipedia.

I'm looking for a company that can support me in a project to build a small biomass plant, with pyrolysis system.
Can any of you help me contact a thick company?
I'm waiting for you.:bekle:

The path you've embarked on is "pionieri", so finding a company that invests in the idea without a safe return, is in my opinion very complicated.

 

[numero1]

However, it could be very profitable if you have some luck.
Hi.
