Solid fuel is compressed with other materials, such as pine needles, fir, which
remains after receiving fir oil. But these little cakes distributed and sold vicinity of
these plants (Table 1).

In this regard the prospect of a second fuel briquettes from coal is relevant and
timely. To obtain fuel pellets need to develop their production sequence:
-
determine the type of coal, the choice of binding material;
-
determining the chemical composition of coal and its physical properties;
-
develop criteria briquetting;
-
testing the resulting secondary heat coal;
-
comparison of briquettes from primary and secondary coal;
-
a combination of raw materials for making fuel pellets.
Research results. The main objectives of the study in addition to theoretical
analysis is an experimental characterization of coals composition and properties.
The main tasks:
•
Research raw materials for the manufacture of components of raw material
mixture;
•
Analysis of existing man-made varieties of products of industrial production
and technology use in the construction industry;
•
Experimental research and development of new technologies of material for
use in new directions.
The list of tasks also include finding and developing solutions to issues of
environmental safety of certain regions of Dnipropetrovsk region, which arose due to
contamination of large areas large-heating waste - ash-removal (OS) power plants and
chemical waste;
•
Production of coal briquettes from recycled charcoal;
•
The combination of technology and briquetting mechanical activation;
•
Analysis of heat transfer products;
•
Definition calorie coal;
•
Testing of mechanical properties of the product in laboratory equipment.
