Super Heater Coils Manufacturer India | IBR Superheater Coils
Radiant, Pendant & Convection Superheater Coils up to 620°C
Modern Boilers designs and manufactures high-performance radiant, platen, and convective superheater coils for high-pressure power generation and industrial process boilers. Cold mandrel bent with strict ovality limits and post-weld heat treatment, our coils ensure maximum steam enthalpy and heat absorption while resisting high-temperature flue gas corrosion and creep fatigue.
What is Super Heater Coils?
Super Heater Coils (also spelled superheater coils) are ASME and IBR 1950 certified tubular heat exchanger banks in water-tube industrial boilers that elevate saturated steam temperature up to 540°C–620°C above its saturation point without increasing pressure. Modern Boilers Pvt. Ltd. (Nagpur, India) is a premier manufacturer of radiant, pendant, and convective super heater coils fabricated from high-temperature alloy steels (ASTM SA213 T11, T22, T91) and carbon steels (SA210C) with 100% radiographic weld testing, cold mandrel bending down to 1.5D CLR, and official IBR Form III-A inspection certification.

Specifically engineered for the aggressive turbulence inside AFBC (Atmospheric Fluidized Bed Combustion) furnace beds. Our studded bed coils utilize automatic capacitor-discharge welded alloy studs that anchor protective refractory matrices, dissipating abrasive bed particle impacts while maintaining superior in-bed evaporative heat transfer rates.
Modern Boilers bare tube and spiral high-frequency welded finned economizers recover sensible heat from escaping boiler flue gases to preheat incoming boiler feedwater. Each 6°C rise in feedwater temperature increases boiler efficiency by 1%, yielding immediate fuel cost savings across continuous industrial operations.
Our heavy-wall distributor, collector, and mixing steam headers are designed to handle pulsating steam dynamics and thermal expansion cycles. Built from seamless alloy pipes with hot-pulled extruded stubs or full-penetration welded forged weldolets, our headers eliminate stress concentration points and flow turbulence.
