Related Boiler Pressure Parts & Fittings
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.
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.
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.
