Fly Ash Composition
Fly ash is a byproduct of the combustion of pulverized coal in thermal power plants. It consists of fine particles that are carried away by the flue gases. Fly ash is primarily composed of inorganic minerals, with varying amounts of carbon and trace elements. The composition of fly ash can vary depending on the type of coal, combustion conditions, and the efficiency of the power plant.
Key Gases Present in Fly Ash
1. Carbon Monoxide (CO): Fly ash can contain trace amounts of carbon monoxide, which is a colorless and odorless gas. It is produced during the incomplete combustion of carbonaceous materials, including coal. Carbon monoxide is a toxic gas and can have adverse effects on human health and the environment.
2. Aluminum Oxide (Al2O3): Fly ash often contains significant amounts of aluminum oxide, which is a compound of aluminum and oxygen. Aluminum oxide is a common constituent of many minerals and is known for its high melting point and resistance to corrosion. It can be used in various industrial applications, including the production of ceramics, refractories, and abrasives.
3. Silicon Dioxide (SiO2): Fly ash is rich in silicon dioxide, also known as silica. Silicon dioxide is a compound of silicon and oxygen and is one of the most abundant minerals on Earth. It has many industrial uses, including the production of glass, ceramics, and silicon chips. Silicon dioxide is also a major component of sand and is commonly found in soil and rocks.
4. Calcium Oxide (CaO): Fly ash can contain calcium oxide, which is a compound of calcium and oxygen. Calcium oxide, also known as quicklime, is widely used in construction, agriculture, and various industrial processes. It is a key ingredient in cement and can also be used as a desiccant, pH regulator, and in the production of chemicals.
Conclusion
In summary, fly ash coming from thermal power plants contains gases such as carbon monoxide, as well as inorganic compounds like aluminum oxide, silicon dioxide, and calcium oxide. These gases and compounds have various industrial applications but can also pose environmental and health risks if not properly managed.

Fly Ash coming from thermal power plants contains which of the followi...
• Statement 1 is incorrect: Fly Ash coming from thermal power plants does not contain carbon monoxide.
Fly Ash
• Fly ash is one of the residues generated by coal combustion, and is composed of the fine particles that are driven out of the boiler with the flue gases.
• Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminum oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coalbearing rock strata.
• Fly ash is a fine powder which is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water it forms a compound similar to Portland cement. Fly ash can be used as prime material in blocks, paving or bricks; however, one of the most important applications is PCC pavement. PCC pavements use a large amount of concrete and substituting fly ash provides significant economic benefits.
• Major concerns about using fly ash concrete include:
• Slower strength gain.
• Seasonal limitation.
• Increase in air-entraining admixtures.
• An increase of salt scaling produced by higher fly ash.
• Fly Ash coming from thermal power plants does not contain carbon monoxide.
