Abstract

Offer method of briquetting, differs that from existing a warming-up simultaneously of all array of material "from within" and shutdown of process of heating at his forming. Such approach allows to spread the amount of the modified material of preforms, promote his calorie content and get new properties, in т. ч. and increase of durability.

It was set for this purpose, that the chosen fillers (branches of trees of birch of 60%, stem of sunflower of 10% and husk of sunflower of 10%) of not subjected to thermal decontamination at a temperature below 220 С. For the quality mixing of these fillers with a polyethylene the temperature of fusion at mixing must fold 190 С. A polyethylene in default of oxygen is stable at a temperature 290 С.

Temperature of beginning of thermodestruction polyethylene on air folds 240 С. of the Use of warming-up "from within", assists that mass transfer easily boiling and water-soluble connections on the surface of standard and strengthens even without application of high-pressure, flexible electromagnetic technology (ЕМТ) is worked out with the use of extraordinarily high-purity (Microwave) of making of fuel preforms from vegetable and arboreal wastes. Automation of an offer technology allows to provide a high load of equipment and decline of unit cost factor. Duration microwave drying of wood diminishes more than in 10 times comparatively with traditional treatment.

For many regions of Ukraine of the use of own hard biopropellant more expedient than the use of coal or oil products, because a mine-out from local raw material biopropellant costs 2-4 times cheaper.

Thus research-and-development, sent to expansion of base of application of biomass in power plants, improvements of technologies of making of biopropellant, in particular from vegetable wastes and compos on their basis, are actual for the decision of tasks of substituting for natural gas the alternative types of fuel and important for providing of power safety of Ukraine.

A dominant value after the amount of formation of wastes belongs to wood, sunflower, corn, and one of rational methods of their utilization there is the use of the last as raw material for making of hard fuel. Processes of drying of vegetable wastes for a grant to them of necessary physical and technical and operating descriptions are power-hungry enough and protracted.So the expenses of energy on drying and pressing of raw material fold to 60% from all expenses at the production of fuel preforms from vegetable wastes. From the variety of method of realization of this process most effective from the point of view of the productivity, energy-savings, ecological cleanness, qualities of the prepared product are drying of the electromagnetic field of ultrahigh-frequency energy.

 

Keywords: fuel preforms, vegetable and arboreal wastes, flexible technology.
