What are the factors that affect nozzle efficiency?
The traditional nozzle adopts the structure of cast steel. 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 stable combustion at 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.
What are the factors that affect the efficiency of silicon carbide nozzles?
Suzhou Chunyi Monitoring Program-controlled Equipment Manufacturing Co., Ltd. was established in 2011, the company's main business for thermal power plants, large power station boiler manufacturing enterprises, industrial boiler manufacturing enterprises, petrochemical, cement, steel and other industries to solve the wear-resistant, high-temperature, corrosion-resistant design and manufacturing integration solutions.
