Henan Notes suspension tube boiler manufactur gas leak problem Henan precautions gas boiler leaking problem: ① the inner wall of the Henan gas boiler leaks: leak is also divided into the inner wall of the drum and the provision of water leakage and water cooling pipe leakage drop, if the former is relatively small leakage eye, can be Wabu same steel, after Patching flaw detection. Leak needs to be replaced before the tube, replacing a large area. ② Henan leaking gas boiler handhole: re-try transducer mounted at an angle, to see if there is a hand hole cover deformation, if deformed, the first correction, and then the green tape wrapped in a layer of a uniform mat, and preferably consistent position before overhaul . ③ gas leak in the boiler drum: the higher cost of repair costs, mainly to see the location and size of the leak leak point where, if the old boiler appears oozing red pot of water, indicating that water quality problems, probably because of low alkalinity or water metal corrosion caused by dissolved oxygen is too high. Low alkalinity can adding sodium hydroxide or trisodium phosphate to a pot of water, dissolved oxygen in water is too high to be resolved by the deaerator. ④ leaking water treatment system: first check whether the gas boiler corrosion, if you need to descaling the boiler corrosion, leaks repaired part, and then circulating water treatment, adding agents, equipment and other materials were boiler corrosion, scale, protection . ⑤ boiler flue gas leak: check is not the boiler tube or tube sheet due to cracks, if the need to change the pipe, see Wabu flue used material, aluminum, and stainless steel may be carbon steel or argon welding aluminum wire, iron acid electrode material directly. ⑥ leaking valves: Valves leaking packing should be added to or replacement of the valve.
Secondly, due to severe water shortage in the suspension tube boiler manufactur furnace tube overheat, blast furnace tube will cause an accident, but the accident is quickly blast furnace tube caused by lack of water. Therefore, burst pipes, water shortages and often reinforce each other. Therefore, in the operation of the boiler water level closely monitored, to prevent water boiler, tube rupture is very important.
Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial steam suspension tube boiler manufactur as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Note that, these condensing suspension tube boiler manufactur cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.
