Silicon Carbide Nozzle
generally adopts the structure of cast steel. The appropriate swing of the burner nozzle can change the position of the flame center to adjust the reheat steam temperature level; the dense and lean pulverized coal burner can prevent coking and high-temperature corrosion in the furnace, and has stable ignition. Good stability under low load and low NOx emissions. After the primary air cast steel nozzle of the burner is burnt and deformed, the deviation between the flame center of the furnace and the design value is large, and the nozzle size is large, the initial momentum of the jet is reduced compared with that before burning, the range is shorter, and the rigidity is poor, the pulverized coal catches fire not far from the nozzle, the temperature near the nozzle is high, and slagging is easy to occur. The primary air nozzle of the burner needs to be replaced after burning. When replacing, the powder pipe connected to the outside of the burner needs to be disassembled, and the primary air nozzle of the burner and the nozzle are pulled out together for replacement, and then installed. The workload is large, the environment is poor, labor-consuming, time-consuming and expensive, resulting in great economic losses.
The silicon carbide nozzle of the burner produced by our company adopts a special process and uses silicon carbide material for one-time casting molding. After high temperature heat treatment, it has higher strength, wear resistance, high temperature resistance, and corrosion resistance. The service life is 3-5 times that of the cast steel nozzle, which improves boiler efficiency, reduces NOX emissions, saves energy and protects the environment, reduces maintenance costs, and improves economic benefits.
Our company can produce various types of silicon carbide nozzles according to customer drawing requirements.

The quality and efficiency of the use of silicon carbide nozzles are also related to many factors, and the purchase of silicon carbide nozzles needs to consider the system conditions and operating conditions.
The traditional nozzle adopts the structure of cast steel, and the proper swing of the burner silicon carbide nozzle can change the position of the flame center to adjust the reheat steam temperature level; the dense and lean pulverized coal burner can prevent coking and high temperature corrosion in the furnace, and has the characteristics of stable ignition, good low load stability and low NOx emissions.
The integral silicon carbide nozzle can effectively prevent fouling and slagging: when the boiler is fired with easy fouling and slagging coal, fouling, coking and slagging are easy to occur at the burner nozzle, thus affecting the combustion performance of the boiler. Because the conventional burner nozzle is made of cast steel, the material will deform in high temperature environment for a long time, resulting in uneven nozzle and eddy current;
