Cyclone Dust Collector for Biomass & Boiler — Manufacturer & Supplier
Vayuvents Pvt. Ltd. manufactures and supplies industrial cyclone dust collectors for biomass & boiler dust separation applications across India and export markets.
Biomass-fired boilers burning rice husk, bagasse, wood chips, and agro-residues generate flue gas with high particulate loading that must be cleaned before stack discharge to comply with CPCB emission standards.
Cyclone dust collectors in the flue gas path between boiler and stack serve as the primary ash separation stage — removing bulk flyash before the downstream multi-cyclone, wet scrubber, or bag filter achieves final emission compliance.
Vayuvents manufactures high-temperature cyclone dust collectors for biomass boiler flue gas service in heavy-gauge MS, with refractory lining options for very high temperature applications and ash rotary valve discharge for continuous operation.
How It Works in This Application
Biomass Combustion and Ash Generation
Biomass combustion generates flyash carried in the flue gas — rice husk and bagasse producing significantly higher flyash loadings than wood chips.
High-Temperature Flue Gas Entry
Biomass boiler flue gas exits at 200 to 400°C and enters the cyclone at this elevated temperature — requiring appropriate construction materials and sealing.
Flyash Separation
The cyclone centrifuges flyash particles from the hot flue gas stream, collecting them in the hopper below for discharge as bottom ash.
Emission Control at Stack
After the cyclone and downstream bag filter or scrubber, the cleaned flue gas meets CPCB standards — typically 50 to 150 mg/m3 for biomass boiler stacks.
Recommended Variants
High-Temperature MS Cyclone
6 to 10mm MS for biomass boiler flue gas up to 350°C — most common configuration.
Most RecommendedRefractory-Lined Cyclone
Castable refractory lined for higher temperature biomass applications above 350°C.
Multi-Cyclone Battery
Higher-efficiency multi-cyclone for biomass boilers where single cyclone alone cannot achieve emission compliance.
Rotary Valve Discharge
Motor-driven rotary airlock for continuous ash discharge during boiler operation.

FAQs
Plain MS cyclones handle biomass boiler flue gas up to approximately 350°C. Above this, refractory-lined cyclone construction is required. Most biomass boilers with economisers have flue gas below 300°C at the cyclone inlet — within MS limits.
No. A single cyclone reduces outlet concentration to 1,000 to 5,000 mg/m3 from typical biomass boiler inlet loadings — well above the CPCB standard of 50 to 150 mg/m3. A downstream multi-cyclone, wet scrubber, or bag filter is required for full emission compliance.
A motor-driven rotary airlock valve at the cone bottom provides continuous ash discharge while preventing boiler draft air from bypassing up through the ash hopper — which would drastically reduce cyclone efficiency.
Rice husk ash is a valuable pozzolanic material used in cement and concrete. Bagasse ash contains potash and is used as agricultural fertiliser. Vayuvents can advise on ash quality based on your fuel type.
Yes. Vayuvents supplies to rice mills, sugar mills, oil expeller plants, and agro-processing facilities across rural India. Simple, maintenance-free designs suitable for operation by general workers.
6 to 8mm MS plate for the body and 8 to 10mm for the cone is adequate for rice husk boilers with inlet gas below 300°C. The rotary valve must also be rated for the flyash temperature.
