Biofuels own hands

Today, many are beginning to realize that the burning of fossil fuels someday will lead mankind in a deadlock.However, power generation from renewable energy sources can not yet cover all the needs of the economy.But what if we turn to the experience of our ancestors, and to use fuel of biological origin.After all, in ancient China, we were able to produce biogas from natural raw materials.This fuel is not inferior in their physical properties to other fuels.So let's look at how you can develop biofuels with their own hands.

What is biogas?Biogas

- a generic name mix large quantities of organic volatile compounds which have high flammability.It is able to be formed in an anaerobic environment in the process of decomposition of any organic material.The main condition - the lack of oxygen and high humidity.The raw material for biogas production can be any organic substrate: manure, tops of the plants, grass, sawdust, waste wood production, straw and even household was

te.All this can be successfully used to heat not only the greenhouses and utility rooms, and entire homes.

Mainly any biogas consists of methane, carbon dioxide and other gaseous impurities, such as hydrogen sulfide.The smaller it contains carbon dioxide, the higher the quality of the product.Because carbon dioxide is non-flammable gas.In many cases, processing one kilogram of organic matter provides as much as 500 grams.biofuels.This is a very high rate, which is rare in other areas.

There are many advantages in the use of biogas.

  • biogas Cost is today at par with gasoline, but its purity is much higher, which gives a good saving on maintenance of boilers that run on this fuel.
  • There is no dependence on the availability and cost of oil.
  • Sources of renewable biofuels can be considered as distinct from hydrocarbons.After all, the decomposition of biomass will always occur, as there is life on Earth.Oil, gas and coal will sooner or later end in the depths, because they were formed millions of years, in strictly defined circumstances, where the planet is no longer today.
  • reduces the total amount of harmful emissions into the atmosphere by about 65%.
  • Possibility of independent production.It is impossible to extract oil with their own hands and make it into gasoline, but produce biofuels under certain knowledge everyone can.Moreover, the raw material for the production do not have to look long.

What influences the production of biofuel?

What is crucial for those who set out to produce biofuels with their own hands at home - so it is mainly the environment.Indeed, the higher the temperature, the more successful the result will be the necessary chemical reactions, by means of which gas will be released.This was the main reason that the first equipment that produces biofuels in the home, was constructed and put into operation in the region with a warm climate.However, in cold conditions, it is possible to produce biofuel.Just for this it is necessary to take measures to insulation installation design or entry in the design of its devices for forced heating of the working chamber, for example, hot water.In addition, the creation of the unit may be affected by the raw material itself, which should be effectively and rapidly degrade, contain a lot of liquid.There should be no cleaning agents and other drugs that slow down the decomposition process, so kill the anaerobic bacteria, performing the fermentation process.

process of making biofuels

So, is how to produce biofuel with their hands, and what the available materials can be used in the process.To fully understand the need to make out a few common options.

biofuel production from conventional manure

Dung, is undoubtedly the most popular raw material for the production of artisanal by a large number of biogas.Therefore, if you live in the countryside and keep any livestock, the purchase of plant for the production of biofuels will be economically viable, as it may well pay off for 2 - 3 years.

Maximum violent reaction to the release of large amounts of gas takes place in horse manure.However, this manure is hard to get, because few people today breeds of horses in his farm.Much easier is the case with cow, goat and swine.It is not as effective but still able to produce sufficient amounts of gas.

On the basis of manure creates mixed with other waste, by which is produced and a combustible gas, which is used for heating the house.Here are some popular mixture:

  • Any available manure and leaves of trees in a ratio of 7: 3.
  • manure and ordinary straw.
  • manure and sawdust - 7: 3.
  • manure and waste from the production of flax - 7: 3.
  • mixture of cow and horse manure - 1: 1.
  • mixture of manure with household waste - 4: 6.

As already mentioned at the outset, the technology of the production is based on all known fermentation.It occurs entirely in special sealed containers at a sufficiently high temperature.Excess water in the process, just removed, and the released biogas is supplied to the gas burner installed in a furnace that heats certain premises.This gas can be successfully fed in boilers to natural gas, but will need a burner changeover in this case.This is because the methane content in the biomass is considerably less than for natural gas.Today, incidentally, has already produced a special combination boilers to operate not only on the conventional gas, but also on biofuels.

gas production from charcoal

Biofuels in the home it is possible to produce from conventional charcoal, which everyone loves to use the outdoors to roast barbecue.However embarrassment that stores a charcoal is expensive.Fortunately, its price is purely speculative, as dictated by the great demand is for use in Mangalia.Cost of production of the same product several times lower.Therefore, if you learn how to make a charcoal, the costs will be fully recouped of the thermal energy, which will be produced later.To make their own charcoal, you need to have some knowledge and not very "crooked" hands.Consider two ways:

  1. Charcoal from the barrel. To produce a sufficient amount of coal is fine metal barrel 200 liters.In its lower part is welded fitting under the forced air injection device.For these purposes, you can use a regular vacuum cleaner, or mount a device with a fan.The barrel of a fire, which gradually added to the wood.

It can be any timber waste.When wood is half barrels, it is necessary to completely close and seal the raw clay or wet ground.At this point, there is the forced air supply.There is a very intense burning coal to produce all the familiar.The disadvantage of this method is increased zoloobrazovanie.Therefore, after each batch must be cleaned from the ash barrel.

  1. charcoal from the pit. this way coal is always burning in the forest.Today, it is prohibited without coordination with the fire control authorities because of frequent cases of forest fires.To obtain such approval, the following conditions must be met: a place for burning should be located on a vast glade or outside the forest, and it should be a wide strip webs;within the reach of sparks should not be dead wood and old trees.In addition, the environmental control authorities must draw the conclusion that the production will not harm the environment.

For a small production of digging a hole 50 cm deep and 80 cm in diameter. The walls of the pit must have a slope.On thoroughly compacted bottom of the pit make a fire with birch bark and thin twigs.Then it was added gradually cleaved, having a length not exceeding 30 cm. Each subsequent layer is added only after the previous firing.Firewood should be very close to each other.About three hours needed to complete burning of firewood.When this happens, and the pit is completely filled with burnt wood, they need to fill the dry leaves and earth.All this is tamped and left for 2 - 3 days.During this time the embers from wood become underground in charcoal, chill and can be folded into the bag.If there is such a need, you can dig a hole larger or make them a little.

As you can see both ways quite time-consuming, but they do not require almost no financial cost, since need to buy expensive and high-grade wood for charcoal production.You can use dry trees in a forest or waste timber production.

Burning this charcoal in solid fuel fired boilers allows to obtain high-quality and high-temperature pyrolysis bio-gas, which has a very high combustion energy.Unlike the conventional wood, charcoal can give many times more heat from the same fuel volume.

biofuels from rapeseed

From rapeseed is also possible to produce a quality biofuel.To well understand this procedure, you can independently carry out a fairly simple and accessible to anyone chemical experience.It should take five grams of caustic salt and very quickly, so as not to hit the air, pour it into a glass every 2 liter capacity, which has already poured 200 grams of methanol (methyl alcohol).The resulting mixture should be mixed thoroughly.Thereafter, the mixture was added heated to 55 degrees rapeseed oil.For convenience, stirring well as the capacity to use a jar with a lid, in which a hole is cut by a blender.Stirring

mixture should be performed at low speed in a blender for 20 minutes.The mixture was then allowed to stand for 1 hour at a temperature of not lower than 55 degrees.At room temperature will need the whole day.After this time, the bottom of the banks will be glycerin, and the rest will be filled with a yellow liquid.This is the biofuel that we wanted to get.It needs to be filtered and can be used in boilers operating on liquid fuel.Of course, to produce biofuels in the 3 liter cans quite profitable, so for this purpose there are special installation.

So, taking into account all of the above the obvious advantages of using biofuels as alternatives to popular today different types of fuel types, can say with certainty that it is entirely appropriate and reasonable solution, for example, for the farmer.Provided that, if you are familiar with some thematic literature, containing more detailed explanations of methods and the production of biofuels schemes, add to it all their own high-quality knowledge and skills, then you will surely succeed.

And remember: any raw material that you plan to stream used to produce biofuels, should be perfectly decomposed and contain a large amount of liquid is enough.Best of all these conditions are satisfied manure, and production with its use very simple.Furthermore, the feed should not be present any foreign substances that may retard the reaction or lower the quality of the resulting biofuel.
