To analyze the material used methods for guests and conducted research part of
the ash-removal power station. Characteristics of fly ash and ash components used
reagents. For analysis process used laboratory glassware GOST 25336-82.
For the experiment used materials and reagents:
•
Ash and slag waste power station.
•
Secondary coal.
•
Anthracite coal (grade T)
•
Distilled water GOST 6709-72
•
coal tar
As the starting material used slag and ash-removal, which is a waste power plants.
Ash - unburned residue is formed from mineral impurities fuel at its full combustion
and sediment from the flue gas ash-catching devices. Our processing technology used
slag waste slag of fly ash after coal combustion fuels. Fly are acidic and basic.
Our material is a combination of fly ash and slag removal, which we analyze and
subject to processing. So In terms of the formation of large-our material. In accordance
with GOST 25 818 -91 our material refers to coal of "T". Coal of this brand has this
description: Among the structures of organic matter in coal selected 4 types (telinitova,
posttelinitova, prekolinitova and kolinitova) which are consecutive single-stage
process of decomposition of lignin-cellulosic fabrics. The total porosity of coal also
varies by extreme law; for Donetsk coal grade D, it is 22-14%, coal of K and 4.8%
increases (perhaps because of loosening) to 10-15% for coal of TV Seasons coal
divided into micropores (avg. diameter 500h10-10 meters and micropores (5-15) h10-
10 meters). The space occupied by mesopores. Macroporous decreases with increasing
stage of metamorphism and micropores - conversely. Mechanical strength of coal is
characterized by its ability to fragmentation, fragility and hardness, tensile strength
compression [3].
Problems with the accumulation and utilization of industrial solid wastes arise and
need to be addressed in every civilized country. Not the exception, and Ukraine.
Analysis of works that have become classics, suggests three basic types of activation
of fly ash (or binders based on it): mechanical, chemical and thermal. Received divided
into fractions material analyzed for the content of components in it (Table 2).
