Soot blowing equipment is usually used in our common boiler equipment, including steam blowing, sonic blowing, and shock blowing. Among them, steam blowing is the most widely used one. More practical and reliable soot blowing equipment, when boiler equipment uses steam soot blowing, the soot blowing gun tube is prone to jamming, failure, steam leakage and other faults during the work process. How to deal with these faults? For air leakage and pipe insulation, electric tracing is recommended here
Compared with traditional steam heat tracing, electric heat tracing has the advantages of stable temperature, high heat tracing efficiency, long service life, energy saving and environmental protection. The most important are the small size of the electric heat tracing band, which is a band-shaped body, which can easily adhere to the appearance of the pipeline. The principle of electric energy heating is used to keep the sootblower from freezing and freezing. The intention is to keep the medium in the boiler in a flowing liquid state.
Boiler equipment is usually high in temperature. The general electric heating cable cannot reach the effect of heat preservation and antifreeze. For boiler pipes with steam purging, MI heating cables are usually used. MI heating cables are single or multiple alloys. The electric heating wire is used as a heating source, high purity, high temperature, and fused crystalline magnesia as a thermally conductive insulator. Seamless stainless steel or copper pipes are used as sheaths, which are manufactured by special production processes.
The working temperature of the MI heating cable can reach above 600 ℃, and the outer sheath is made of stainless steel. It can withstand temperatures up to one thousand degrees Celsius, and will not cause problems such as deformation and melting. High temperature requires equipment to be insulated and frost-resistant. The MI heating cable can meet the requirements of high temperature conditions and large heating power, as well as the requirements of high temperature conditions and long-distance pipeline heating. Therefore, the length of the MI heating cable is customized according to demand, and there is no product in stock under normal circumstances. It is necessary to go through the design of the plan, and then use the model clearly after passing the review. Therefore, please communicate with the heat tracing manufacturers before purchasing.
