BOILER ASH. There are two primary forms, bottom ash and fly ash. Bottom ash accumulates at the bottom of the burner while fly ash is collected in the smoke stack scrubber. They have very different chemical and physical properties and are the inorganic constituents of the burned fuel that are not completely combusted.
Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement.
Fly ash is an industrial waste of thermal power stations using pulverized coal. It is finely divided residue, resulting from the combustion of pulverized coal in the boiler, which is transported by the flue gases and subsequently collected by means of electrical or mechanical precipitators.
tom ash) remain in the boiler, but the lighter particles (fly ash), carried by the flue gases, are captured in an electrostatic precipitator. According to a report by the American Coal
Fly ash produced thus possesses both ceramic and pozzolanic properties. When pulverised coal is burnt to generate heat, the residue contains 80 per cent fly ash and 20 per cent bottom ash. The ash is carried away by flue gas collected at economiser, air pre-heater and ESP hoppers.

Fly Ash s the inorganic mineral residue obtained after burning of coal/lignite in the boilers. Fly Ash is that portion of ash which is collected from the hoppers of ESP’s and pond ash is collected from the ash ponds. Bottom ash is that portion of ash which can be collected fro the bottom portion of the boilers.
Boiler tubes extract heat from the boiler, cooling the flue gas and causing the molten mineral residue to harden and form ash. Coarse ash particles, referred to as bottom ash or slag, fall to the bottom of the combustion chamber, while the lighter fine ash particles, termed fly ash, remain suspended in the flue gas.
Brick contains fly ash, Lime, water, and Quarry dust. With the control brick, i.e. 10%, 20%, 30%, 40%, 50% and 60% of the fly ash is replaced with Bagasse ash, the data from the Bagasse ash fly ash brick is compared with data from a standard fly ash brick without bagasse ash.
The advantages of fly ash brick are High compressive strength Lower water absorption Dimensional accuracy. High strength to weight ratio Consumption of less mortor in construction. Conservation of natural resources, like soil, sand etc. Fly ash bricks are now widely used in construction of buildings, pavements, boundary wall etc. Quality
Coal Ash, Fly Ash, Bottom Ash, and Boiler Slag. Finally, there’s boiler slag, the melted form of coal ash that can be found both in the filters of exhaust stacks and the boiler at the bottom. Even this foul sludge has its uses. Boiler slag can be included in roofing shingles (a reasonably safe application) and in structural fill (not as good,
Falsely high oxygen indications from air in-leakage. Side-to-side imbalances may be determined by taking fly ash samples from both the left and right sides of the boiler. One side of the furnace may show a carbon content of say 3%, but on the other side the LOI may be high, say 15%.
Neptune Industries Limited is Leading and Largest Manufacturer of Plant & Machineries for Fly ash Bricks in India and Promoted Green Technology Initiative with advance building materials.
The ratio of fly ash to bottom ash ranges from 70:30 to 80:20 depending on the type of boiler and type of coal. According to the EPA, beneficial uses of fly ash include serving as a raw material in concrete, grout and cement or as a fill material in stabilization projects and road beds.

In this book, a brief introduction to the thermal industry waste fly ash as raw materials in brick construction industry. As on today more than 350 million tonnes fly ash is produced but only 55%
Aug 08, 2019 · The fly ash is a fairly divided residue which results from the combustion of ground or powdered bituminous coal or sub-bituminous coals like lignite and transported by the flue gases of boilers fired by pulverized coal or lignite.
A mixing proportion of 50% fly ash produces a brick with minimum water ab- sorption. Since the bricks contain incompletely burned coal, on burning, the brick is burnt from the outside in-

Autoclaved brick production mix With the chemical composition of raw materials and parts requirements for products varies.
Fly ash is comprised of the non-combustible mineral portion of coal. When coal is consumed in a power plant, it is first ground to the fineness of powder. Blown into the power plant’s boiler, the carbon is consumed — leaving molten particles rich in silica, alumina and calcium.
It can be used for steam curing sand bricks, fly ash bricks, aerated concrete blocks, high strength cement electric pole, concrete piles and other cement products. Besides, it can also be used for wood, pharmaceutical, chemical industry, glass, insulation materials and fishing net processing industries.
The properties of fly ash from co-combustion depend greatly on the burning conditions (the kind of boiler, tem-perature of burning), the amount and chemical composition of the ash from coal and biomass, as well as the share of the biomass in the mixture with coal.

BOILER ASH Boiler ash is a generic term applied to many types of ash produced by the burning of various materials. They are 4 general types of boiler ash commonly available, each with its own chemical and environmental characteristics: Wood Ash – from boilers where wood (or bark) is used as a heating source
Fly ash is a coal combustion by-product – a finely divided residue resulting from combustion of coal in power plants. In the thermal power stations, coal is pulverized into fine powder and pumped into the boiler along with compressed air. Coal powder is fired to generate heat, which in turn produces steam to run the turbine.
