METHOD FOR STORAGE OF FLY ASH OF BROWN COALS
(57) Abstract:
FIELD: ash and slag waste recycling.
SUBSTANCE: invention relates to the field of
recycling of ash and slag waste (ASW) from coal
combustion atthermal power plants(TPP),in particular
fly ash of brown coal after electrostatic precipitators of
large TPP boilers, for use in agriculture. To store fly
ash of brown coal,the content of calcium oxide in which
is 20-50%, before loading fly ash into storage pits dug
in the ground, the bottom and walls of the storage pit
are wetted by spraying dispersed water at the rate of
2-4 l/m2
of irrigated area. Upon completion of the
loading, the fly ash is moistened by spraying dispersed
water jets in the amount of 2-4 l/m2
of the fly ash
surface.
EFFECT: simplification of fly ash storage
technology, its timely delivery to the places of use,
improvement of the quality of fly ash as a mineral
additive to soils, the ability to store for a long time, at
least up to a year.
