Engineered and manufactured in Nagpur, India with 100% material traceability, radiographic weld verification, and Director of Steam Boilers certification.
Top 5 High-Demand Boiler Tubular Components
Specialized manufacturing in alloy & carbon steels with 100% radiographic testing, mandrel cold bending down to 1.5D CLR, and IBR Form III-A inspection certificates.
Super Heater Coils
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.
Studded Bed Coils
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.
Economizer Coils
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.
Boiler Bank Tubes
Generating bank tubes connect the upper steam drum to the lower mud drum in bi-drum water-tube boilers. Precision bent on computerized mandrel benders, each tube is guaranteed to exact curvature templates. Specially annealed tube ends ensure zero-leak roller expansion tightness into drum tube holes without work-hardening or micro-cracking.
Water Wall Panels
Membrane water wall panels form the perimeter combustion chamber of modern water-tube boilers. Fabricated on our automatic submerged-arc welding (SAW) gantries, our gas-tight panels eliminate fugitive flue gas egress, lower refractory maintenance costs, and provide maximum radiant evaporative surface area for rapid steam generation.
Steam Drum
The primary phase-separation vessel for industrial boilers. Modern Boilers fabricates steam drums and mud drums with heavy ultrasonic-tested boiler quality plates, hot-formed ellipsoidal dished ends, and high-efficiency internal cyclone separators that guarantee 99.85%+ steam dryness fraction to prevent turbine blade erosion and superheater tube burnout.
Steam Headers
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.
Feed Water Tank & Deaerator
Modern Boilers feedwater storage tanks and deaerator columns prevent boiler tube pitting and dissolved oxygen corrosion. By elevating water temperature to 105°C and stripping non-condensable gases below 0.005 cc/liter, our vessels ensure reliable suction head for high-pressure feedwater pumps and buffer boiler surge loads.
Package Boiler
Factory-assembled, skid-mounted 3-pass wetback package boilers engineered for rapid on-site commissioning. Featuring high thermal efficiency (> 88%), fully modulating automated burner controls, and compact footprint, our package steam boilers deliver reliable saturated steam within 20 minutes from cold start.
Pipe Fittings & HP Bends
Certified forged and seamless high-pressure pipe fittings engineered to withstand thermal cycling and pulsating hydraulic shock in power plant piping. Sourced with full mill traceability and certified under Indian Boiler Regulations Form III-C, our fittings ensure leak-free integrity across critical steam and feedwater circuits.
Industrial Chimneys
Engineered for thermal power plants, sponge iron kilns, and process boiler installations, our industrial steel chimneys deliver aerodynamic stability and safe high-altitude atmospheric dispersion of combustion flue gases. Fabricated in compliance with IS 6533 standards for structural safety under severe cyclone wind and seismic loading.
Coal Nozzle
Directly exposed to abrasive high-ash Indian coal and severe radiant furnace temperatures up to 1100°C. Modern Boilers precision-casts coal nozzles from proprietary high-chromium white cast iron and Ni-Hard alloys, providing over 3× longer operating life compared to standard fabricated mild steel nozzles.
Air Nozzle / Bed Tuyeres
Even fluidization is the single most vital factor in preventing catastrophic bed clinkering and boiler trips in AFBC and CFBC boilers. Our directional and mushroom-type air nozzles are engineered with calibrated discharge orifices that provide uniform air velocity distribution across the entire bed plate while preventing bed material back-sifting into the windbox.
