India is one of the world's largest rice producers. Rice husk is abundant, carbon-neutral, and often available at a fraction of the cost of coal or oil. For rice millers, it is a "zero-cost" fuel that turns waste into energy.

While rice husk has a lower calorific value (3,000 kcal/kg) than coal, it is significantly cheaper. It burns cleanly and is more sustainable, though it requires specialized furnace designs to manage its high silica ash.

Yes. The CO₂ released during the combustion of rice husk is equal to the amount absorbed by the rice plant during its growth, making it an environmentally responsible choice.

In our HUSKPOWER boilers, we use bubbling bed technology. This keeps the fuel particles in a fluid-like state, increasing "residence time" to ensure complete combustion of every husk particle, achieving efficiencies up to 76%.

Rice husk ash contains over 90% silica, which is highly abrasive. We use specialized stainless steel ferrules at the tube inlets to protect them from erosion, significantly extending the life of the boiler tubes.

Unlike traditional manual feeding, our top-feed system uses high-velocity fans to spray husk into the furnace. This ensures even distribution, prevents "clumping," and allows for automated operation.

We manufacture the HUSKPOWER series in capacities ranging from 1 TPH to 6 TPH. For larger requirements (up to 20 TPH), we offer specialized Fluidized Bed Combustion (FBC) systems.

Yes. While optimized for husk, the furnace can be adapted to burn other agro-waste like sawdust, crushed peanut shells, or small wood chips.

On average, a 1 TPH boiler consumes approximately 230–250 kg of rice husk per hour to produce 1,000 kg of steam, depending on the husk's moisture content.

Rice husk produces about 20% ash. Our boilers feature large, easy-access ash pits and can be fitted with Multi-cyclone Dust Collectors to ensure clean emissions and easy ash disposal.

To achieve maximum efficiency (above 74%), we highly recommend an APH. It uses waste heat from flue gases to heat the combustion air, speeding up the ignition of the husk.

• Rice Mills: For parboiling and drying paddy.
• Textile Mills: For dyeing and processing.
• Solvent Extraction Plants: For oil recovery processes.
• Distilleries: For fermentation and distillation heating.

Absolutely. All industrial units from indianboilers.com are manufactured under Indian Boiler Regulations (IBR), ensuring they meet the highest safety and material standards.

Because of the high ash content, the furnace should be de-ashed daily. The smoke tubes should be cleaned weekly to prevent soot buildup, which can lower efficiency.

Standard features include Low Water Cut-offs, Dual Safety Valves, and VFD-controlled fuel feeders to prevent over-pressurization or fuel-clogging.

Prices vary based on capacity and automation. For 2025, the approximate rates are:

• 1 TPH to 2 TPH: ₹1,500,000.
• 3 TPH to 6 TPH: ₹15,00,000 – ₹35,00,000.
• Large FBC Units (10 TPH+): Upwards of ₹60,00,000.

The price depends on Steam Capacity (TPH), Working Pressure, the inclusion of Pollution Control Equipment (like Bag Filters), and the level of Feeding Automation.

For a rice mill using its own husk, the ROI is incredibly fast—often between 6 to 12 months. For other industries buying husk, the savings over Diesel or Coal typically result in an ROI within 18 months.
