Dyeing and printing plants use a range of steam and heat systems. Biomass pellets may be assessed where the boiler and fuel-handling equipment are suitable, but fuel choice alone does not determine fabric quality, operating cost or emissions compliance. This guide outlines the plant-specific checks to make before a trial.
Map the Plant's Steam and Heat Requirements
Depending on the process, steam or heat may be used for:
- Dyeing machines and continuous ranges, subject to their process specifications.
- Stenters, ageing chambers, washing and soaping equipment, depending on the plant configuration.
- Boilers, thermic-fluid systems or heat exchangers, as specified by the equipment supplier.
Record actual steam demand, pressure, temperature, load changes and operating hours. Use those measurements and the process team's requirements to assess any proposed fuel.
Fuel Data and Process Quality
BBI agro-pellets are specified at sulphur below 0.1%, with batch lab reports available on request. Fuel properties and emissions should be assessed against the boiler and site requirements; product fuel data alone does not establish steam quality or a fabric-quality outcome.
Fuel Specifications for Comparison
| Parameter | BBI Biomass Pellets | Current fuel | Other supplier fuel |
|---|---|---|---|
| GCV | BBI specification: 3800–4200 Kcal/kg; confirm batch result | Use the delivered grade or batch result | Use the delivered grade or batch result |
| Moisture | BBI specification: below 10%; confirm batch result | Use the delivered grade or batch result | Use the delivered grade or batch result |
| Ash | BBI specification: below 10%, typically 2–8% depending on feedstock | Indian coal ash is generally 25–45%; check the delivered grade | Use the delivered grade or batch result |
| Sulphur | BBI specification: below 0.1%; confirm batch result | Use the delivered grade or batch result | Use the delivered grade or batch result |
| 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 |
| GPCB Emission Profile | Depends on boiler and controls | Depends on boiler and controls | Depends on boiler and controls |
Emissions and Site Consent Conditions
Before changing fuel, review the plant's applicable consent conditions and emission-monitoring requirements with its environmental team.
Stack-emission results depend on the boiler, fuel batch and pollution-control equipment. Fuel specifications do not establish compliance; use site measurements against the applicable requirements.
Fuel Storage and Handling at Dyeing Units
Plan the storage area using the delivered quantity, supplier's bulk-density data, chosen storage method and safe access requirements. Do not assume a storage-volume advantage without comparing the actual fuels and site layout.
Keep pellets dry and protected from rain. Confirm the storage design and handling controls with the site's safety and operations teams.
Supply and Minimum Order Details
BBI supplies biomass pellets with a Minimum Order Quantity of 25 MT per delivery. Determine how long an order will last from the site's measured consumption, operating schedule and delivery plan.
Standard bulk contracts are 50 MT/month and large-volume contracts are 200+ MT/month. BBI is based in Kadi, Gujarat; confirm availability, delivery timing and freight for your location in the quotation. Contact BBI to discuss your requirements.
Frequently Asked Questions
Can biomass pellets affect the quality of reactive dyes or disperse dyes?
Fuel choice alone cannot establish whether steam meets a process or product-quality requirement. Review the boiler, steam treatment and process controls with the plant's engineering and quality teams.
Are biomass pellets suitable for high-pressure steam boilers used in jet dyeing?
Suitability depends on the boiler, fuel feed system, required pressure and operating conditions. Have the boiler OEM or a qualified engineer assess the proposed fuel and any changes before a trial.
What GPCB documentation supports pellet-fuelled boiler compliance?
BBI provides a batch lab report (GCV, moisture, ash, sulphur) on request. Your Consent to Operate application typically also needs your own stack test results; check requirements with GPCB. Contact our team to request a sample report.
How does delivery work for units in Surat's GIDC areas?
Delivery timing and vehicle arrangements depend on quantity, destination and availability. Confirm the expected dispatch and delivery window, freight and unloading plan in the quotation. Contact BBI with your location and required quantity.
What is the trial order process?
BBI's minimum order quantity is 25 MT. Before ordering, confirm that the quantity suits your storage and monitored trial plan, and check boiler compatibility with the OEM or a qualified engineer. Contact BBI with your product requirements and delivery location to discuss specifications and current availability.
