Discussion on Burner Silicon Carbide Nozzle
burner is to spray the pulverized coal air mixture (primary air) supplied by the pulverized coal preparation system and the secondary air required for combustion into the furnace at a certain concentration and speed, respectively, in a suspended state Realize stable ignition and combustion device.
1. The structure of the silicon carbide nozzle must be simple, not easy to block, easy to repair and replace, long service life, and improve economic efficiency.
2, silicon carbide nozzle adopts integrated casting molding process, high temperature resistance, wear resistance, reduce maintenance costs.
Talking about Silicon Carbide Desulfurization Nozzle Design Follow Principle
Suzhou Upper Spring Instrument Monitoring Program Control Equipment Manufacturing Co., Ltd. supports the design, manufacture, debugging, service and supporting overall services of silicon carbide wear-resistant material accessories. It has built a 7200 ㎡ manufacturing base and more than 30 high-precision processing equipment. The factory workshop has passed the ISO9001:2015 quality system certification, one-year warranty, solutions within 1 hour after-sale, and free technical guidance.
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;
