ABSTRACT
The primary aim of the article is to present the result of the research conducted on identifying key factors that ef-
fects physical attributes of eco-friendly coal briquettes, namely moisture degree and proportion of ingredients of coal
briquettes.

Ключевые слова:
угольные брикеты, долговечность, зольность, физические характеристики, степень
влажности, время воспламенения.
Eco-friendly coal briquettes are inexpensive solid
fuels made from coal dust and organic waste available
to use in both domestic and industrial sectors. The iden-
tified coal reserves of Uzbekistan are equal to 1382.8
million tons and predicted reserves are more than 3.5
billion tons [1]. Addition to this, 85.9% of all electricity
produced in Uzbekistan belongs to electricity taken
from thermal power plants (TPPs) and one of the main
fuel sources of TTPs are coal, after natural gas. These
numbers show that coal industry will remain to be one
of the main fuel industries of the republic for the next
couple of decades.
The finely broken coal, coal dust, inevitably pro-
duced during mining process. Pure coal dust is difficult
to burn as it is both hard to arrange adequate airflow
throw a fire of these small pieces, also it tended to be
drawn up and out of the chimney by the draught, giving
visible black smoke[2]. And doubtlessly burning finely
broken coal causes serious environmental problems.
Meanwhile, there is a possibility of creating eco-
friendly solid fuel product with high heating power and
durability value from composition of pure coal dust and
biomass.
