Air Nozzle / Bed Tuyeres Manufacturer & Supplier India
Precision Fluidizing Bed Tuyeres to Prevent Clinkering & Dead Zones
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.
What is Air Nozzle / Bed Tuyeres?
Air Nozzle / Bed Tuyeres is an IBR 1950 certified boiler pressure component manufactured by Modern Boilers Pvt. Ltd. in Nagpur, Maharashtra. 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.

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.
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.
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.
