Summary:
This article explains how the Steamax REC works, the problems it addresses in traditional roasting furnaces, and its key benefits for poha, murmura, rice, and dal manufacturers.
How does REC work? (Renewable Energy Combustor)
Poha, murmura, and dal manufacturers need consistent heat for roasting and drying. Traditional furnaces often burn fuels such as rice husk and sawdust, but poor combustion control, heat loss, and fly ash can create operating challenges.
Steamax developed the Renewable Energy Combustor (REC) to help these industries improve biomass combustion and upgrade existing roasting systems.
Problems with Traditional Roasting Furnaces
Conventional furnaces can create several challenges for manufacturers:
- Excessive fuel consumption: Poor air and fuel control can lead to incomplete combustion and wasted energy.
- Fly ash and smoke: Inefficient burning can increase particulate emissions and affect workplace conditions.
- Heat loss and maintenance: Unsuitable construction materials and damaged furnace linings can reduce performance.
- Operating costs: Replacing an entire roasting setup can require significant investment.
A suitable combustion upgrade can help address these issues without necessarily replacing the entire roaster.
How Does Steamax REC Work?
The Steamax REC is designed to upgrade compatible roasting systems. Its main working features include:
- Installation: The existing furnace beneath the roaster is replaced with the REC unit, subject to site and equipment suitability.
- Automatic fuel feeding: A hopper-based mechanism feeds biomass into the combustion chamber, reducing manual fuel handling.
- Multi-fuel combustion: The system handles different biomass fuels, depending on their size, moisture, and compatibility.
- Primary and secondary combustion: Air enters the main combustion chamber, while a secondary combustion arrangement helps burn remaining combustible gases and particles.
- High-temperature fire bricks: Specially designed refractory materials help withstand operating temperatures and protect the combustion chamber.
- Air and fuel control: Coordinated control of combustion air and fuel supports more efficient burning.
Together, these features are designed to improve combustion and provide consistent heat for roasting operations.
Key Benefits of the Steamax REC
- Better combustion: Improved air and fuel control can reduce incomplete burning.
- Reduced fuel waste: More effective combustion may lower fuel consumption, depending on the fuel and operating conditions.
- Lower fly ash carryover: Better combustion and suitable system design can help reduce particulate carryover. Actual emissions depend on fuel quality and operating conditions.
- Less manual handling: Automatic feeding can reduce the labour needed to supply fuel.
- Improved working conditions: Better-controlled combustion can help create a cleaner workplace.
- Upgrade existing equipment: You can retain a suitable existing roaster instead of replacing the entire setup.
Where Can REC Be Used?
Steamax REC is designed for roasting and drying applications in industries such as:
- Poha manufacturing
- Murmura production
- Chana roasting
- Dal processing
- Other compatible food-processing applications requiring controlled heat
The correct fuel and system configuration should be selected according to the process temperature, heat requirement, and existing equipment.
REC vs Traditional Furnaces
| Feature | Traditional Furnace | Steamax REC |
|---|---|---|
| Fuel Feeding | Often manual | Automatic hopper feeding |
| Combustion Control | May have limited control | Designed with air and fuel control |
| Biomass Compatibility | Depends on furnace design | Designed for multiple compatible biomass fuels |
| Combustion Stages | May rely mainly on primary burning | Includes primary and secondary combustion |
| Furnace Lining | Depends on construction materials | Uses high-temperature fire bricks |
| Operating Costs | Depend on fuel use and maintenance | Potential savings depend on fuel, efficiency, and operating conditions |
| Retaining Existing Roaster | Depends on the setup | Designed to work with compatible existing roasters |
Is REC a Suitable Upgrade for Your Roasting Unit?
Before selecting a Renewable Energy Combustor, assess your current furnace, daily fuel consumption, required roasting temperature, and available biomass fuels. These details help determine whether the REC can be integrated into your operation and what improvements may be achievable.
Steamax can help evaluate your requirements and identify a suitable configuration.
Frequently Asked Questions
REC stands for Renewable Energy Combustor, a biomass combustion system developed for compatible roasting and heating applications.
The system is designed for multiple biomass fuels. Compatibility depends on fuel properties such as moisture, particle size, and calorific value.
Improved combustion can reduce fuel waste, but actual savings depend on the existing furnace, fuel quality, heat demand, and operating conditions.
Not necessarily. REC is designed to upgrade compatible existing roasters, although a site assessment is needed to confirm suitability.
