High-Efficiency Rice Husk Fired Boilers: Cost-Effective Steam for Industrial Power
At IndianBoilers.com, we specialize in engineering high-performance Husk Fired Boilers specifically designed to tackle the unique challenges of rice husk combustion. As a carbon-neutral fuel source, rice husk offers an incredible cost advantage, particularly for rice mills and agro-processing units. Our specialized “HUSKPOWER” series ensures stable steam generation, maximum fuel savings, and clean combustion through advanced top-feed and FBC technologies.
Engineered for the Silica Challenge
Rice husk contains up to 25% silica ash, which is highly abrasive. Unlike standard solid fuel boilers, our systems are reinforced with protective stainless steel ferrules at tube inlets and optimized flue gas velocity controls to prevent erosion and extend the service life of your equipment.
Key Features & Performance
- Advanced Combustion Technology: Available in Internal Furnace Top-Feed (up to 6 TPH) and Fluidized Bed Combustion (FBC) designs for larger capacities.
- Pneumatic Top-Loading System: Our innovative top-feed system uses high-velocity fans to spray husk evenly into the furnace, ensuring a stable fuel bed and eliminating common nozzle failures.
- High Thermal Efficiency: Integrated with Air Pre-Heaters (APH) and Economizers to achieve thermal efficiency between 78% and 85%.
- Three-Pass Fully Wet-Back Design: Maximizes heat transfer area while minimizing radiation losses and thermal stress on the reversal chamber.
- IBR Compliant Construction: Manufactured strictly under Indian Boiler Regulations using premium IBR-grade materials for high-pressure safety.

The Economic Advantage: Why Switch to Husk?
- Unmatched ROI: With fuel costs being nearly zero for rice millers and significantly lower than coal or diesel for others, most units see a payback period of just 6 to 12 months.
- Carbon Neutral Footprint: Burning rice husk completes a natural carbon cycle, helping your facility comply with environmental norms and ESG goals.
- Stable Energy Costs: Protect your business from the price volatility of imported coal and furnace oil by using locally sourced agro-waste.
- Valuable Byproduct: The collected Rice Husk Ash (RHA) is rich in silica and can be sold to the cement and construction industries, creating an additional revenue stream.
Core Industry Applications
Our husk-fired systems are the preferred choice across India for:
- Rice Mills: For parboiling, drying, and sterilization of paddy.
- Textile Industry: Cost-effective steam for dyeing and processing.
- Distilleries: High-pressure steam for fermentation and distillation.
- Solvent Extraction: Reliable thermal energy for oil recovery processes.
Pollution Control & Compliance
We ensure your plant remains environment-friendly. Every husk boiler is equipped with a high-efficiency Multi-Cyclone Dust Collector (MCDC) or Bag Filter to capture fine silica particles, ensuring emissions comply with strict State Pollution Control Board (SPCB) norms.
