01
Coal Transportation
Raw coal is first transported to coal power plants, where it undergoes a combustion process to generate energy.
PFA (Fly Ash)
Pulverised Fuel Ash (PFA), or fly ash, is a byproduct of burning pulverised coal in power plants. Collected from flue gases, it serves as a valuable additive in cement production. By replacing a portion of Portland cement with PFA, manufacturers can enhance the strength and durability of concrete while also reducing costs. This not only leads to significant savings in production but also promotes more sustainable construction practices by lowering the carbon footprint.
Benefits of PFA in Cement Production
Enhanced Strength
Improves the long-term strength and durability of concrete structures
Cost Savings
Reduces production costs by replacing expensive Portland cement
Sustainability
Lowers carbon footprint and promotes sustainable construction practices
Quality Concrete
Produces higher quality concrete with improved workability
The PFA Production Process
From raw coal to high-quality fly ash for industrial applications
02
High-Temperature Combustion
The raw coal is ignited in the power plant's furnace and burned at high temperatures. As the coal combusts, it breaks down, producing heat for energy generation and creating various byproducts, including the fine particles that will eventually form fly ash. Reaching the correct combustion temperature is crucial to ensure efficient burning and optimal fly ash production.
03
Collection & Processing
In the third and final step, the coal is completely burned, leaving behind fine particles known as fly ash. This fly ash is collected from the exhaust gases using filtration systems, such as electrostatic precipitators or baghouse filters. The collected fly ash, now free from impurities, can be repurposed for various industrial applications, such as in the production of cement and concrete.
Industrial Applications
The collected fly ash, now free from impurities, can be repurposed for various industrial applications:
Cement Production
Primary use as a supplementary cementitious material, replacing up to 30% of Portland cement
Concrete Manufacturing
Enhances concrete properties including strength, durability, and resistance to chemical attack
