Spinning and textile facilities use different combinations of steam and process heat. Biomass pellets may be assessed where the fuel-handling equipment and boiler are suitable, but compatibility, cost and emissions outcomes depend on the site. This guide outlines the information a Surat mill should check before considering a trial.
Steam and Heat Demands in Spinning Mill Operations
Depending on the facility, process heat may be used for:
- Thermic-fluid or other heating systems serving synthetic-fibre processes, where present.
- Yarn conditioning, drying or heat-setting equipment, depending on the product and process.
- Steam or humidification systems used in particular production areas.
- Dyeing or finishing processes at integrated facilities.
Map the actual heat users, required temperatures and pressures, operating hours and load variations before evaluating a fuel.
Compare Current Fuels Using Site Data
A mill may use coal, furnace oil, natural gas or a combination, depending on its equipment and supply contracts. Compare current delivered prices, fuel test data, useful heat demand and measured boiler performance rather than relying on a general market estimate.
- Furnace oil and natural gas: Use current supplier invoices and the equipment's measured consumption to establish the comparison basis.
- Coal: Indian coal ash is generally 25 to 45% according to the Ministry of Coal; use the delivered grade and batch data for a site-specific comparison.
- Biomass pellets: BBI agro-pellets are specified at GCV 3800–4200 Kcal/kg, moisture below 10%, ash below 10% (typically 2–8%, depending on feedstock), and sulphur below 0.1%; batch lab reports are available on request.
Fuel Data for a Cost Comparison
| Parameter | BBI Biomass Pellets | Current fuel | Other coal or fuel |
|---|---|---|---|
| GCV | BBI specification: 3800–4200 Kcal/kg; confirm batch result | Use the actual delivered fuel's test result and reporting basis | Use the actual delivered fuel's test result and reporting basis |
| Moisture | BBI specification: below 10%; confirm batch result | Use the supplier's data | Use the supplier's data |
| Ash | BBI specification: below 10%, typically 2–8% depending on feedstock | Use the supplier's data | Indian coal ash is generally 25–45%; check the delivered grade |
| Sulphur | BBI specification: below 0.1%; confirm batch result | Use the supplier's data | Use the supplier's data |
| Cost per unit of useful heat | Calculate from delivered price, batch GCV and measured efficiency | Calculate from delivered price, batch GCV and measured efficiency | Calculate from delivered price, batch GCV and measured efficiency |
| Carbon Classification | Renewable (agro-residue) | Fossil fuel | Fossil fuel |
For a mill currently using furnace oil, estimate the difference from current delivered fuel invoices, measured consumption, batch GCV and boiler performance. Any annual cost comparison should state its assumptions and be checked against the mill's operating data; a generic saving range would not apply to every plant.
Emissions and Consent Conditions
Review the facility's current consent conditions before changing fuel. Stack-emission results depend on the boiler, fuel batch and pollution-control equipment; measure them at the site against the applicable requirements.
Thermic Fluid Heater Assessment
A thermic fluid heater should only be considered for pellets if the unit and its fuel-handling system are designed or approved for the proposed fuel. Confirm the system's design limits, burner and feeder requirements, and fuel specification with the OEM or a qualified engineer.
For a proposed conversion, obtain a plant-specific engineering assessment and define any supplier support and charges in writing. Contact BBI to discuss product specifications.
Supply Logistics from Kadi to Surat
BBI is based in Kadi, Gujarat. The minimum order quantity is 25 MT; standard bulk contracts are 50 MT/month and large-volume contracts are 200+ MT/month. Confirm freight, dispatch timing and delivery arrangements for each order.
Calculate storage needs using the agreed delivery quantity, the supplier's product data, storage method and safe access requirements at the mill.
Frequently Asked Questions
Are biomass pellets suitable for thermic fluid heaters?
Suitability depends on the heater design, burner and feeder, required operating range, fuel properties and applicable conditions. Have the OEM or a qualified engineer assess the specific unit before any conversion or trial.
What is the delivery timeline from Kadi to Surat?
Delivery timing depends on the order, dispatch schedule, transport and destination. Confirm the expected delivery window and any recurring schedule in the written quotation or supply agreement. Contact BBI with the required quantity and delivery location.
How do biomass pellets compare to coal on total cost including maintenance?
Compare delivered prices, batch GCV and measured boiler performance on an equal useful-heat basis. Assess maintenance and ash-handling costs separately using the mill's operating records; do not assume a fixed cost advantage.
What is the minimum order for a trial supply to our Surat mill?
Our MOQ is 25 MT. Contact our team with your boiler or TFH specifications, current fuel consumption, and any GPCB compliance requirements and we will prepare a detailed supply proposal.
Does BBI provide technical support during the fuel switch?
Confirm technical-support availability, scope and any charges with the supplier before placing an order. Boiler settings should be reviewed with the OEM or a qualified engineer. Contact BBI to discuss product information.
