It has two main challenges: Low Bulk Density (it's very light and takes up lots of space) and High Silica/Potassium content, which can lead to ash melting (slagging) if not managed correctly.

Our boilers can handle both. However, Baled Straw is easier for transport and storage, while Shredded Straw is better for automated, consistent feeding and higher thermal efficiency.

The Gross Calorific Value (GCV) of paddy straw is typically 3200 to 3500 Kcal/kg, making it a highly viable and cost-effective alternative to expensive fossil fuels.

Yes. IndianBoilers.com manufactures these units in strict accordance with Indian Boiler Regulations (IBR), ensuring safety and compliance for high-pressure industrial steam applications.

Paddy straw ash melts at a lower temperature (~850°C). We use Water-Cooled Grates or specialized Reciprocating Grates with controlled primary air to keep the temperature below the ash fusion point.

For large-scale operations, a Traveling Grate or Reciprocating Grate is best as it continuously moves the fuel and prevents the high-silica ash from sticking to the grate bars.

We provide Extra-Large Feed Hoppers and specialized "anti-bridging" agitators to ensure that the light straw doesn't get stuck in the feeding system.

Paddy straw has high volatile matter. Our Secondary Air Nozzles create high turbulence in the furnace, ensuring these gases burn completely, which prevents black smoke and maximizes heat recovery.

Yes. These are multi-fuel biomass boilers. Our furnace designs are versatile enough to handle a mix of agricultural residues depending on seasonal availability.

It has a relatively high ash content (12% to 18%), mostly composed of silica. We provide automated Submerged Ash Conveyors to handle this volume cleanly and continuously.

To prevent erosion from the abrasive silica, we use lower flue gas velocities and install erosion shields on the first row of boiler tubes to extend their lifespan.

Due to the high ash content, we integrate Automatic Soot Blowers (Steam or Sonic) that clean the tubes during operation to maintain high heat transfer efficiency.

For stable combustion, moisture should be below 15–20%. If the straw is too wet, it will produce white smoke and significantly reduce the boiler's steam output.

Yes. We offer PLC-based automation where the fuel feed rate is synchronized with the steam demand, reducing the need for manual labor and ensuring steady pressure.

By giving paddy straw an industrial value, farmers are incentivized to sell it to factories instead of burning it in the fields. This significantly reduces seasonal smog and air pollution.

Since paddy straw is often available at a fraction of the cost of coal or pellets, most industrial units recover their investment in 10 to 15 months through fuel savings.

We equip our Parali boilers with Multi-cyclone Dust Collectors (MDC) and Bag Filters to ensure that fine silica dust and particulates are captured before the air leaves the chimney.

Yes. Under various "Waste-to-Energy" and "Biomass Mission" schemes, companies can often access subsidies or low-interest loans for installing crop-residue-based boilers.

Based in Ahmedabad, we have optimized our furnace geometry specifically for Indian crop residues. We offer a rugged, IBR-certified design that is built to handle the abrasive and bulky nature of paddy straw for 24/7 industrial use.
