refractory recrystallized reaction bonded sisic silicon carbide burner tube nozzle for kiln furniture
silicon carbide burner nozzle properity:
Reaction bonded silicon carbide spiral nozzles are critical components of thermal power plant, large furnace, desulfurating and dedusting complete equipments. The products have high strength, high hardness, high thermostability, anticorrosion and antifraying and so on. They have long life in hard condition. The nozzle of our company: spray liquid drop uniformly, runner is clear and no jam. Now we can produce screw type, cyclone type and liquid column type. And they have been used in several power plant and in good condition.
