Fighting against POLLUTION to Save Environment

Air Pollution

FLY ASH COLLECTION SYSTEM

Most factories are equipped with biomass fired boilers using coal, rice husk, bagasse, etc. Huge quantity of burnt biomass and partially unburnt Fly Ash is generated in boilers which escapes into the flue gases. Emission must comply with Pollution Control Board norms. Recently, several cases have come to light where factories in India had to shut down due to excessive fly ash emissions and strict Government enforcement. This pollution severely harms the environment and human health.

In view of availability of in-house design & engineering expertise and fabrication facilities, we undertake turnkey projects from concept to commissioning to achieve the desired objectives.

We have designed and supplied efficient Fly Ash Arrestors, Venturi Scrubber Cyclonic type Wet Dust Collectors which effectively arrest 97% to 99% of particles and bring down the final exhaust emission to below 100 mg/Nm³, significantly below Pollution Control Board norms.

Venturi Scrubbers are used where high collection efficiency is required for fine particulate matter, including sub-micron particles. The gas then passes through a cyclonic scrubber where separation of liquid droplets takes place. The slurry is discharged at the bottom while cleaned gases exit through the top outlet.

Our Fly Ash Collector can be installed before or after the ID fan. It is compatible with existing systems with minimal ducting changes to maintain clean and pollution-free surroundings. The system is effectively used for:

Coal Dust, Lime Dust, Sugar Dust, Carbon Black Flue Gas, Rotary Kilns, Torch Cutting Fumes, Induction Furnaces, Steel Re-Rolling Mills, Cupola Furnace, Sponge Iron Plants, Aluminium Chloride Dust & Vapours, Cement Kiln, Chlorine, HCL, Zinc Oxide Dust, Mineral, Pigment, Wax, Silica, Resin Dust & Ammonia Scrubbing.

Performance Guarantee
  • Collection of 97% to 99% ash particles.
  • Exhaust emission level: 50 – 100 mg/Nm³
