The traditional cone-expanding flame ring is made of cast steel. The taper and the stabilizing tooth ring are separately manufactured. The taper is composed of four pieces. The main function is: primary air diffusion, which promotes the recirculation zone. However, the expanded cone and the stabilizing toothed ring of the cast steel are not wear-resistant, corrosion-resistant, high-temperature resistant, and have a short service life, resulting in great economic loss.
Our company's silicon carbide expansion cone flame-retardant ring is made of one-piece casting, high strength, wear resistance, corrosion resistance, high temperature resistance, and the service life is 3 to 5 times of the cast steel taper ring, which improves boiler efficiency and reduces NOX emissions, energy saving and environmental protection. The invention solves the problems that the cast steel expanded cone stable combustion tooth ring is not wear-resistant, easy to burn, and fall off. Our company can produce various types of silicon carbide expansion cone flame-retardant ring according to customer's drawing requirements.
