Economiser Coil
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.
Bending Techniques
To maximise heat transfer efficiency, the economiser coil's tubes must properly curve and line with the flue gas route. To do this, we apply two sophisticated bending methods:
Cold Bending with 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.
Hot Bending for Tighter Spaces
We use the hot bending technique when there is limited space within the boiler. This strategy allows us to attain tighter bend radii while staying below an R/D ratio of 1. Our economiser coils integrate perfectly into any boiler arrangement due to their bendability
Our coils utilise tubes with diameters ranging from a modest 31.8 mm outer diameter (OD) to a substantial 51 mm OD, catering to the diverse requirements of various boiler systems.

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
Economiser in boilers help the system last longer by reducing the thermal stress on the components produced by cold feed water entering the boiler.
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.
