Comparison of Silicon Carbide Nozzle and Cast Steel Nozzle
silicon carbide nozzle and cast steel nozzle:
1, integral silicon carbide nozzle, which can effectively prevent fouling and slagging: when the boiler is fired with easily 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 material, this material will deform in high temperature environment for a long time, resulting in uneven nozzle and eddy current.
2, cast steel material is also prone to high temperature corrosion, nozzle surface due to corrosion pits make the surface uneven, roughness increased significantly. These two factors will lead to casting steel nozzle prone to contamination, hanging slag, coking problems, serious will block the nozzle, resulting in security risks.
How to prevent the silicon carbide nozzle clogging problem?
3. The silicon carbide nozzle has good temperature resistance, anti-erosion and anti-corrosion characteristics, which makes the silicon carbide nozzle structure can be kept flat for a long time, the surface can be kept smooth and clean, and the roughness is low. These characteristics can make the silicon carbide nozzle still have good anti-slag fouling ability when burning coal that is easy to coke and slag. And silicon carbide nozzle has a large number of burning Xinjiang coal, Mengdong coal, Zhundong coal and other easy slagging coal application performance, the overall performance is good, significantly improve the cast steel nozzle prone to coking slagging problem, improve combustion performance, reduce maintenance workload, save costs.
Suzhou shang chun yi monitoring program control equipment manufacturing co., ltd. has excellent technical team, many engineers and relevant technical background of boiler factory. With experience in large-scale overseas projects such as Pakistan Muza and Iran Sahante, it supports complex customization and brings forth new strengths through the old. It develops more than 8 new products every year, with an annual production capacity of 600 sets and a guaranteed supply cycle.
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.
