steam drum boiler cfb wuxi huang
The importance and necessity of the importance and necessity of industrial steam drum boiler cfb wuxi huang inspection cycle of periodic inspection of industrial boilers. Industrial boilers to provide steam and hot water production for industrial boiler or everyday use. Generally refers to a pressure less than or equal to the rated working 2.5MPa boiler. Internal inspection of industrial boilers, industrial boilers is the condition of the process of life, from time to time, request a regular boiler inspection rules "of the boiler furnace safety checks. Therefore, the findings may affect the safe operation of the various defects of industrial boilers, and take effective measures to eliminate or use the direct monitoring of industrial boilers or stop using industrial boilers, prevent accidents and ensure safe operation of the boiler. China is the world's largest country industrial boilers, internal inspection to determine the reasonable period of industrial boilers is very important. In the current boiler periodic inspection rules "(hereinafter referred to as the inspection rules boiler), industrial boiler internal inspection cycle is based on each industrial boilers conclusions of the examination is certain: the conclusion of the test is allowed to run, usually every two years. Inspection findings after running rectification, the rectification to determine the test cycle is complete, restrictions conclusions of the examination running test cycle needs to be shortened. According to inspection and use of maneuverability, the shortest cycle is generally six months, and the longest period is set to two years, which is prescribed to check the boiler within a predetermined range. Users want to check a longer period, in order to save costs and reduce downtime inspection; inspection agency hopes to shorten the inspection intervals to reduce detection risk, increase revenue inspection; regulators want companies to maintain the safety in production. Efforts to reduce the burden on businesses. Objectively speaking, the shorter the trial period, the smaller the risk, the higher the socio-economic costs; the longer the trial period, the greater the risk, the lower the social and economic costs. Rationally defined internal inspection cycle industrial boilers, to ensure safe operation of the boiler, can also reduce the social and economic costs.
Third, the maintenance dry
When using the longer shutdown maintenance method. This is done; pot of water put the net after shutdown, residual heat boiler using a drying furnace, timely removal of residual scale and pot residue was then placed on the tray containing a desiccant within the drum and grate, Finally, close all valves, manhole and hand hole door. Regular inspection and maintenance, and timely replacement of the desiccant failure.
Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast steam drum boiler cfb wuxi huang steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
In hot water steam drum boiler cfb wuxi huang, how to prevent back-chamber tube plate crack?
Tubesheet before back to the combustion chamber the boiler work in three backhaul usage worst site, a long period of high and low temperature thermal stress, likely to cause the tube end thermal fatigue cracking, is where this configuration the boiler is the most prone to problems.
