Industrial manufacturers in Bangladesh need a reliable source of steam for production, heating, drying, processing, cooking, sterilization and other industrial operations. When a factory has access to rice husk, wood chips, sawdust, biomass briquettes, coconut shell, bagasse or other solid biomass fuels, a Biomass Multi Fired Steam Boiler can be an effective alternative to boilers that depend on a single fuel.
Trust ResourcesBD supplies and imports industrial boiler solutions in Bangladesh, including biomass and multi-fuel steam boiler systems. According to the company, Trust ResourcesBD has been among the early suppliers to introduce imported Biomass Multi Fired Steam Boiler solutions to the Bangladesh market and has built its boiler business around industrial customers requiring dependable steam-generation equipment.
What Is a Biomass Multi Fired Steam Boiler?
A Biomass Multi Fired Steam Boiler is an industrial boiler designed to burn more than one type of solid fuel to generate steam. Depending on the boiler design and combustion system, suitable fuels may include rice husk, wood chips, sawdust, biomass pellets, briquettes, coconut shell, groundnut shell, bagasse and other agricultural or wood-processing residues.
The exact fuel combination must be selected according to the boiler’s combustion system, fuel moisture, particle size, calorific value and ash characteristics. For example, rice husk has different combustion characteristics from wood chips or biomass pellets, so a boiler should not be specified simply by listing several fuels. Fuel testing and proper boiler sizing are important for stable operation.
Modern biomass boilers may use systems such as chain-grate firing, fixed-grate firing or fluidized-bed combustion. Automatic fuel feeding, forced-draft and induced-draft fans, ash removal, feedwater systems, control panels and dust-collection equipment can be included depending on the project.
Why Choose a Multi-Fuel Biomass Boiler?
The main advantage of a multi-fuel system is flexibility.
A factory may have access to one biomass fuel during one season and another fuel at a different time. A multi-fired boiler allows the plant to work with several approved fuels instead of depending entirely on one source.
Common industrial biomass fuels include:
* Rice husk
* Wood chips
* Sawdust
* Biomass pellets
* Biomass briquettes
* Coconut shell
* Groundnut shell
* Bagasse
* Corn cobs
* Other suitable agricultural residues
Commercial boiler manufacturers publish different fuel ranges and efficiency figures for their specific designs. For example, some biomass boiler designs specify rice husk, wood chips, pellets, sawdust and shells, while other systems are designed around a narrower fuel range.
Advantages of Biomass Multi Fired Steam Boiler
1. Multiple Fuel Options
The boiler can be configured for several suitable biomass fuels. This gives factories greater flexibility when fuel availability or pricing changes.
2. Lower Dependence on One Fuel
A factory that relies on only one fuel can face production problems if that fuel becomes expensive or difficult to obtain. A properly designed multi-fuel system provides alternative fuel options.
3. Uses Locally Available Biomass
Bangladesh has many agricultural and wood-processing residues that can potentially be used as boiler fuel. Rice husk is particularly relevant to rice-processing operations, while wood residues and sawdust can be available around furniture, sawmills and wood-processing industries.
4. Suitable for Continuous Industrial Steam
With an appropriately sized combustion and feeding system, biomass boilers can provide continuous steam for industrial production. Automatic fuel feeding can reduce manual fuel handling and help maintain more consistent firing.
5. Potential Fuel-Cost Savings
The actual operating cost depends on the fuel’s calorific value, moisture, ash content, availability, transportation cost and boiler efficiency. Therefore, the cheapest fuel per kilogram is not necessarily the cheapest fuel per ton of steam.
6. Reduced Waste Disposal
Where suitable biomass residues are already generated by the factory, using them as boiler fuel can turn an industrial by-product into a useful energy source.
Biomass Boiler Efficiency
Boiler efficiency depends on the complete system rather than the boiler name alone.
Important factors include:
* Fuel moisture
* Fuel calorific value
* Combustion efficiency
* Excess air
* Furnace design
* Heat-transfer surface
* Flue-gas temperature
* Feedwater temperature
* Ash characteristics
* Load level
* Fuel feeding system
* Operator control and maintenance
Published manufacturer specifications show that biomass boiler efficiency varies considerably by technology and fuel. One commercial FBC multi-fuel boiler, for example, lists thermal efficiency of up to approximately 88% ± 2%, while another biomass chain-grate boiler lists design efficiency in the 78–83% range under stated reference conditions. These figures should therefore be treated as equipment-specific rather than as a universal efficiency figure for every biomass boiler.
For a Bangladesh factory, Trust ResourcesBD can assess the customer’s actual fuel and steam requirement before recommending the boiler configuration.
Available Boiler Capacities
Biomass steam boilers are available in different capacities depending on industrial requirements. Capacity is commonly expressed in **TPH (tons per hour)** or **kg/hr**.
For example:
* 1 TPH = approximately 1,000 kg of steam per hour
* 2 TPH = approximately 2,000 kg of steam per hour
* 4 TPH = approximately 4,000 kg of steam per hour
* 6 TPH = approximately 6,000 kg of steam per hour
* 8 TPH = approximately 8,000 kg of steam per hour
* 10 TPH = approximately 10,000 kg of steam per hour
The required capacity should be calculated from the factory’s actual steam demand, operating schedule, peak load and process requirements. Oversizing a boiler can increase capital and operating costs, while undersizing can restrict production.
Typical Facilities and Accessories
A complete Biomass Multi Fired Steam Boiler project can include much more than the main boiler body.
Depending on the design, a complete package may include:
* Biomass fuel hopper
* Automatic fuel feeding system
* Chain grate or other combustion system
* Boiler drum and pressure parts
* Furnace
* Water-tube or fire-tube heating surfaces
* Forced-draft fan
* Induced-draft fan
* Feedwater pump
* Economizer
* Air preheater
* Automatic or semi-automatic control panel
* Temperature and pressure instruments
* Safety valves
* Water-level controls
* Blowdown system
* Ash removal system
* Chimney or stack
* Dust collector
* Bag filter or other particulate-control equipment where required
* Water treatment system
* Steam piping and valves
* Fuel storage and handling equipment
The final equipment list should be prepared according to the boiler capacity, fuel characteristics, steam pressure and factory layout.
Where Are Biomass Multi Fired Boilers Used?
Biomass steam boilers can be used in many industries where process steam is required.
Typical applications include:
Rice Mills: Rice husk can potentially be used as boiler fuel when the combustion system is designed for it.
Textile and Garment Industries: Steam may be required for dyeing, finishing, washing and other processes.
Food Processing: Steam is used for cooking, processing, sterilization and heating.
Dairy and Beverage Plants:Process heating and cleaning operations may require steam.
Paper and Pulp Industries: Steam can be used in production and drying processes.
Wood and Furniture Industries: Sawdust and wood residues can be considered as biomass fuels when suitable for the selected boiler.
Edible Oil and Agro-Processing Plants: Agricultural residues may provide a locally available fuel source.
Biomass Boiler Price in Bangladesh
There is no single fixed price for a Biomass Multi Fired Steam Boiler in Bangladesh.
The total project price can change according to:
- Steam capacity
- Working pressure
- Boiler technology
- Fuel type
- Number of compatible fuels
- Manual or automatic fuel feeding
- Automation level
- Economizer and air preheater
- Dust-collection system
- Water-treatment equipment
- Chimney and ducting
- Installation requirements
- Import and shipping costs
- Electrical and control requirements
- Civil and mechanical installation work
As a broad international market reference, current supplier listings show biomass steam boiler equipment ranging from several thousand US dollars for smaller units to well above US$100,000 for larger or more highly equipped systems. Bangladesh import records also show that actual imported boiler values vary widely according to capacity and equipment package.
For this reason, publishing one fixed Bangladesh price can be misleading. A proper quotation should be prepared after confirming the required TPH, steam pressure, fuel type, operating hours and accessories.
How to Select the Right Biomass Boiler
Before purchasing a biomass boiler, a factory should provide the supplier with several important details:
- Required steam capacity in TPH or kg/hr
- Required working pressure
- Existing boiler information, if replacing an old unit
- Available biomass fuels
- Approximate daily or monthly fuel quantity
- Fuel moisture condition
- Required operating hours
- Factory location
- Available boiler-house space
- Desired automation level
- Existing water-treatment system
- Existing chimney and steam piping
The supplier can then recommend the combustion technology, boiler capacity and auxiliary equipment.
Boiler Efficiency Depends on Fuel Quality
One of the most important points for biomass boiler buyers is fuel quality.
Two biomass fuels with the same weight can produce very different amounts of useful heat. Moisture reduces the useful energy available from fuel and can affect combustion stability. High ash content can increase ash-handling requirements and may create combustion or grate problems.
Therefore, fuel analysis should be considered before finalizing the boiler design. A reliable supplier should discuss fuel specifications instead of simply promising a particular efficiency percentage.
Safety and Boiler Registration in Bangladesh
Industrial steam boilers are pressure equipment and must be operated under the applicable Bangladesh boiler laws and requirements.
Under Bangladesh’s **Boiler Act 2022**, boilers used in Bangladesh must be registered with the Office of the Chief Inspector of Boilers, and boiler operation requires the applicable operating licence.
The Office of the Chief Inspector of Boilers also provides services related to boiler registration, renewal of boiler-use certification and boiler operator information.
The official registration requirements can include construction drawings, pressure-part calculations, inspection and test certificates, manufacturer certificates, P&I diagrams, steam-pipe plans, fee documentation and import documents such as the LC, invoice and bill of lading.
For this reason, customers should choose a supplier that understands the technical documentation and installation requirements needed for the Bangladesh market.
