Boiler hood

Product Name: CFB Boiler Air Distributor Nozzle / Air Cap

Overview
Our fluidized bed boiler air distributor nozzles are precision engineered for Circulating Fluidized Bed (CFB) power generation systems. Positioned on the air distributor plate, these critical components direct high-velocity airflow to fluidize and combust pulverized coal. Manufactured from SS310 heat-resistant alloy, each nozzle is designed to withstand extreme thermal cycling, erosion, and high-temperature oxidation, ensuring optimal combustion efficiency and extended operational life.

Key Features

· Material: High-grade SS310 (UNS S31000) heat-resistant stainless steel — excellent creep strength and oxidation resistance up to 1000°C (1832°F)
· Material Control: Strict chemical composition verification ensures compliance with standards; improper composition significantly reduces service life — our process guarantees full traceability
· Casting Process: Precision investment casting or sand casting with rigorous quality control, depending on geometry requirements
· Air Hole Accuracy: Tight tolerances on air hole position, diameter, and angle — critical for uniform airflow distribution, combustion stability, and preventing bed material backflow
· Custom Configurations: Over 20 years of experience manufacturing dozens of nozzle designs tailored to specific boiler models and operating conditions
· Durability: Optimized wall thickness and wear-resistant design to resist high-temperature erosion and thermal fatigue

Applications

· Circulating Fluidized Bed (CFB) boilers in power plants
· Industrial boilers and biomass power generation
· Coal-fired fluidized bed combustion systems
