We offer a comprehensive range of studded & plain inner/ outer
bed coils that we manufacture from quality carbon steel or alloy
steel. These coils can be customized as per the specific
requirements of the clients. as per I.B.R. 1950. Bed coils are integral components of boilers designed to enhance heat transfer efficiency and optimize steam generation in industrial processes. These coils are strategically positioned within the boiler’s combustion chamber,

Bed Coils Features
The materials used for bed coils in boilers are selected based on their ability to withstand high temperatures, pressures, and corrosive environments typical of boiler operation. Carbon Steel ,Stainless Steel, Alloy Steel ,Inconel and more.
The choice of material depends on factors such as the operating temperature and pressure, corrosion resistance requirements, and budget considerations.
Bed coils are designed as a series of tubes arranged within the fluidized bed chamber. These tubes are often coiled to maximize surface area for heat transfer. where they absorb heat from the burning fuel and transfer it to the surrounding water.
The tubes are usually made of materials that can withstand high temperatures and corrosion, such as carbon steel, stainless steel, or alloy metals. Bed coils are submerged within the bed material, allowing them to come into direct contact with the hot bed material and absorb heat efficiently.
As fuel particles combust within the fluidized bed, they release heat energy, raising the temperature of the bed material. Bed coils absorb this heat energy from the hot bed material, transferring it to the water circulating through the coils.
The heated water generates steam, which is then used for various purposes such as power generation, heating, or industrial processes. Once absorbed, the heat from the combustion gases is transferred to the water circulating within the coils
Proper maintenance of bed coils is essential to ensure their continued performance and longevity. Check the alignment and support of the bed coils to ensure they are properly positioned and supported within the boiler. Make any necessary adjustments or repairs to ensure proper alignment and prevent stress or damage to the coils.
Regular inspection is necessary to check for signs of corrosion, erosion, or mechanical damage to the coil tubes. Cleaning may be required to remove any ash or other deposits that accumulate on the coil surfaces, which can reduce heat transfer efficiency.
