DE102007031277A1 - Fuel, particularly in pellet form, is obtained by injecting processed olive residue, which is derived from olive cultivation using organic or inorganic material selected from chipped wood or sawdust - Google Patents

Abstract

The fuel is obtained by injecting processed olive residue. The olive residue is derived from olive cultivation using organic or inorganic material selected from chipped wood or sawdust. An independent claim is included for a method for producing fuel, which involves: (A) drying purified olive residue; (B) pulverizing the dried olive residue; (C) mixing the dried and purified olive residue with organic or inorganic materials; and (D) mechanically injecting the mixed olive residue with organic or inorganic materials.

Description

Summary:

manufacturing from fuel to the desired one Shape and dimension of the end product, especially in the form of pellets, by pressing olive residues with combustible organic and / or inorganic Substances.

State of the art:

at a worldwide olive oil production of 17,168,915 and 12,547,130 tons per year across Europe enough olive leftovers for the production of the named fuel. After processing the olives is the moisture of the residues about 12%. Olive kernels have a higher calorific value compared to air-dry wood. (Olive kernels 5.6 kWh / kg) (air-dry Wood 4-4.4 kWh / kg)

Consequently is an environmentally friendly and equivalent replacement for fossil fuels Guaranteed fuels.

The Olive residues are also processed or pressed without any additives, z. B. in pellet form.

in this connection However, there is the disadvantage that the pellets burning relatively bad. About that In addition, no perfect combustion is achieved, so that the full Calorific value of the compacts can not be fully utilized.

Task:

The The object of the present invention is a fuel to provide on the basis of olive residues, which also in different species and varieties of selected Olive residues and residues from olive growing, as a biofuel of higher quality and reduced ash content in modern firing systems for heat recovery can be used in the private and commercial sector.

Description:

These Task is fictitious by the features of claim 1 to 5 solved. Therefore The olive residues are made with organic and / or inorganic flammable Blended fabrics and then pressed. The attached components to mix with the olive residues are preferred from the most available and / or selected renewable biomass resources such. B: wood.

at the admixture of wood such as shavings or Sawdust, in the right proportion to the olive residues, arises an excellent renewable biomass species with an improved Calorific value. Preferably, the finished product should be the residual moisture of 7%.

There the volumes of the different materials are different, All measurements were carried out in parts by weight.

Of the Olive residue percentage should be at least 30% to the desired Effect to achieve.

It can be any shape and dimension of the end product in one common Pressing device, stationary or mobile, can be produced as desired.

at the production of compacts are by the pressing and / or supply of dry steam released substances that have a binding effect, to high quality pellets with low dust content and best Achieve abrasion. For wood, it's the wood fiber's own Adhesives (lignin). Lignin is used when supplying dry steam from Liquefied at 150 ° C and needed after the pressing process a long-term cooling.

By the mixing and pressing according to the inventive method is made from the olive residue and the supplied flammable organic and / or inorganic substances z. As wood is a high quality Conglomerate fuel produces its calorific value is higher than z. B. at normal Wood pellets.

Of the fuel according to the invention, is thus an excellent substitute for fossil fuels, being fundamental Advantages in a trouble-free power supply in time-synchronized heating systems, a good metering ability, a clean storage and a high energy output are.

Claims (5)

Fuel, mostly in pellet form, obtained by pressing of processed olive residues through olive growing with organic and / or inorganic substances such as B. wood chips or Sawdust, is mixed. Fuel according to claim 1, recognizable by the comminuted do not rot as well as partially rot and dried olive residue. Fuel according to claim 1 or 2, recognizable by additionally admixed organic and / or inorganic substances in any Shares. Fuel according to claim 2 and 3, recognizable by striking pigmentation. Production process of fuel from olive residues with organic and / or inorganic substances: - drying the cleaned olive leftovers - crushing the dried ones olive residues - mixing the dried and cleaned olive residues with organic and / or inorganic substances z. As wood chips or sawdust. - Mechanical pressing the mixed olive residues with organic and / or inorganic substances in any form z. B. pellet form.
