Description

DESCRIPTION of the invention model having as title:

"Pellets - agroecological energy production"

SUMMARY

The present model of invention concerns in this case the constitution of a pcllets composed of products, agricultural by-products and by-products of the agri-food industry, suitably mixed together, which allow to obtain a specific natural and ecological product that can be used both for combustion in boilers. and stoves of any size and power, as well as systems that use alternative energy heating systems.

Currently there are wood pellets.

DESCRIPTION

The pellets are structured like a small cylinder of compacted material, without any glue or additives and is composed of material coming from annual agricultural crops and waste from agri-food industries.

Product with rather constant chemical-physical characteristics, it allows boilers and stoves a high efficiency and high performance even at low powers.It also represents the form of solid agricultural energy biomass best used by eliminating, with appropriate mixtures, the differentiation of the starting material that would not be feasible as a fuel both for the difference in combustion and for the logistics of the product itself for family consumption.

The materials that make up the pellets are chosen according to the calorific value to be developed and according to the period of the agricultural year in which it is produced.

The materials are: corn (stalk and seed), sunflower (main body, calatidae and seed), pomace, sorghum and rapeseed (for sorghum and rapeseed: main body and seed), straw, pruning and / or thinning residues, expeller of sunflower, grape seeds.

The materials are, after being collected and dried, naturally or artificially, ground and mixed to be then inserted into a pelletizing machine where the mixture undergoes a heat treatment caused by the crushing of the compressor rollers on the walls of the machine itself to then be compressed and thus obtain the finished pellets with a lower percentage of humidity and high compaction.

The development of calories can be greater or equal than the "traditional" wood pellets.

The details of execution may in any case vary without departing from the scope

of the invention and therefore from the domain of the invention patent.

Claims (4)

CLAIMS 1) The pellets described in this model of invention refers to a pellet consisting of material from agricultural products, by-products and by-products of the agri-food industry. 2) Pellets can be used for combustion in stoves and industrial plants that use alternative energy heating systems. 3) Pellets are a natural and ecological product with high performance even with low-power stoves. 4) Calorific properties of the pellets in question and comparison with other fuels: FUEL QUANTITY KILOCALORIES WATT Wood pellets 1kg 4000 4652 Methane 1 m <3> 8200 9537 Diesel 1 liter 10200 11863 LPG 1 liter 11000 12793 Pellets (in object) 1 kg> 5000> 5815 5) Calorific yield of fuels compared to one kg of pellets: FUEL QUANTITY KILOCALORIES RETURNED Wood pellets 1kg 4000 Methane 0.48 m <3> 4000 Diesel fuel 0.39 liters 4000 LPG 0.36 liters 4000 Pellets (on object) 0.80 kg 4000 6) Specific physical and chemical characteristics belonging to the pellet in question: PARAMETER UNIT VALUES Calorific value higher Kcal / Kg> 3500 Calorific value lower Kcal / Kg / t q. > 3000 Diameter (D) mm 5-12 Length (L) mm L <5xD Density kg / dm 3 1-1.4 Apparent density kg / m3> 500 Moisture% weight t.q <15 Ash% weight s s <5 Mechanical durability% weight> 90 Powders% weight <5 Binding agents not present Nitrogen% weight s s <1 Chlorine% weight s s. <0.15 Sulfur% weight s.s. <0.1 7) Market prices of fuels in comparison: FUEL QUANTITY AVERAGE PRICE IN EURO Wood pellets 1kg 0.23 Methane 1m <3> 0.60 0,85 liter diesel LPG 0.73 liter Pellets (on object) 1 kg 0.20 8) Cost / benefit comparison table: FUEL Ο, ΤΙΤΑ 'KILOCAL.
