Economiser Coils for Boilers and Power Plants
RIBO Industries is a specialist in making Economiser coils for boilers and power plants. Ribo Industries is known in the boiler & power plant segment for its component supply to various OEMs as one stop solution for complete manufactured components supply for entire boilers & power plant accessories.
Economiser coils are heat exchanger devices that capture waste heat from hot flue gases to preheat boiler feedwater, significantly improving energy efficiency and reducing fuel consumption by transferring heat before it exits the chimney. Key benefits include reduced emissions, improved overall boiler performance, and extended operational life.
Economiser coils also known as feedwater heaters, heat recovery devices, and heat exchanger coils. Flue gases, a byproduct of boiler combustion, take away heat that is frequently left unused. To harness this untapped energy, economiser coils are positioned strategically along the flue gas route. As hot flue gases flow through the coils, they transfer their thermal energy to the fluid, usually water. This captured heat is then recycled back into the system, preheating the feedwater before it enters the boiler.
Various Bending Techniques followed in the economiser manufacturing process
Cold Bending of Economizer with Booster Techniques
By the name suggests, The economiser tubes are bent at room temperature using booster techniques. This procedure achieves a bend radius that matches the tube diameter (R/D ratio of one). This ideal curvature lowers pressure drops, promotes efficient fluid flow, and improves heat transmission. To prevent tube collapse or deformation, we use unique "booster" procedures during cold bending of Economiser tubes.
Advantages of Cold Bending of Economiser
- Maintains material properties without heat distortion.
- Ideal for larger bend radii and standard configurations.
Hot Bending of Economiser for Tighter Spaces
In Hot bending process, the economiser tubes are heated (typically via induction or furnace) before bending. We use the hot bending technique when there is limited space within the boiler. Our economiser coils integrate perfectly into any boiler arrangement due to their versatile bendability.
Advantages of Hot Bending of Economiser
- Allows tighter bend radii (R/D ratio < 1) for compact boiler layouts.
- Reduces internal stress and risk of cracking.
- Can be used when space constraints demand sharper curves.
Product Benefits
While the core functionality of economiser in boiler focuses on waste heat recovery, they offer additional benefits:
Reduced Emissions
While the core functionality of economiser in boiler focuses on waste heat recovery, they offer additional benefits:
Improved Boiler Efficiency
Preheating the feedwater reduces the energy required in the furnace to achieve the optimum steam temperature, resulting in significant cost savings and a more sustainable boiler operation
Extended Boiler Life
With a tolerance of +3 millimetres, our bend panels are precisely produced to an exceptional degree of straightness. This degree of precision ensures that water or steam flows through the tubes as efficiently as possible, reducing pressure drops and increasing boiler efficiency.
At RIBO, we offer a variety of designs and combinations to meet the individual requirements of each boiler system. Factors such as tube number and arrangement, finned tubes to increase heat transfer surface area, and material selection based on pressure, temperature, and flue gas composition are all considered to provide the optimal solution.
