Efficient Dust Removal Solution for Small Coal-Fired Boilers

Small coal-fired boilers, typically in the 1–10 ton range, are widely used in heating systems, small-scale industrial processes, and rural energy applications. However, emissions from these units often contain fine particulates, sulfur dioxide, and other harmful gases. To meet tightening environmental regulations and ensure cleaner air, installing a reliable dust removal system is critical.

Recommended System: Wet-Type Dust Collector with Spraying Structure

This compact dust collector is specially designed for small coal-fired boilers. It adopts a multi-nozzle spraying mechanism, where high-pressure water is atomized into fine mist inside a cylindrical chamber. The mist forms layered water curtains and dense water films along the inner walls, effectively capturing dust and neutralizing harmful gases.

Key Features & Advantages

• ✅ High Dust Collection Efficiency
  Removes over 95% of particulate matter, ensuring compliance with local emission standards.
• ✅ Integrated Desulfurization & Denitrification
  Achieves over 80% SO₂ removal, while reducing nitrogen oxides and absorbing black carbon.
  Flue gas opacity (Ringelmann scale) is maintained below Level 1, visibly cleaner emissions.
• ✅ Simple Installation & Low Space Requirements
  Compact design suits indoor or outdoor setup. Best installed before the induced draft fan (negative pressure side) to optimize flow and efficiency.
• ✅ Stable Operation Year-Round
  Equipped with frost-resistant water valves and pressure-stabilized nozzles, suitable for winter operation with proper drainage measures.
• ✅ Easy Maintenance
  Periodic belt and motor checks, water level monitoring, and pH balancing (maintaining between 8–10) are all that’s needed for consistent performance.

Typical Applications

• 🔧 1–10 Ton Chain-Grate Boilers
• 🏭 Village and Township Heating Plants
• 🧪 Small Chemical Processing Units
• 🔥 Biomass-Coal Hybrid Furnaces
• 🏫 School or Government Heating Facilities

Installation Tips

• Ensure smoke ducts have minimal bends and are well-sealed.
• Water inlet valves should be kept indoors in cold climates.
• During operation, maintain proper overflow water level and ensure the spray chamber has sufficient water circulation.

Why Choose This System?

Unlike traditional cyclone or dry dust collectors, this wet-scrubbing system combines dust removal, gas purification, and carbon washing in one unit. It offers a cost-effective and space-saving solution for smaller boiler setups, helping users meet emission standards without complex equipment or high operational costs.
