Industrial boilers Defects Defect Analysis industrial boilers cause defects industrial boilers cause analysis Analysis of the industrial boiler plant boiler Class B, rated working pressure 1.0MPa, rated temperature 184 ℃. The use of unit management personnel, operations personnel safety awareness is not high, not strictly enforce the boiler safety management system, boiler water (medium) quality system; the water softener fails, safety consciousness, not timely maintenance. The company location no water, use of pond water. Since untreated pond water containing suspended matter, colloidal matter large excessive, and dissolved substances. Water hardness, long-term use, inside the boiler large amounts of sediment, the carbonate and concentrated attached to the inner surface of the casing pot, water wall tubes; fireman failure to periodically discharge of the sewage system for the boiler. Since the interior of the waterwall tubes attached to a thicker scale, lack of reliable water supply water wall, resulting in performance degradation wall heat transfer, caused by overheating of the metal, plastic deformation strength decreases, under pressure inside, generating bulge, deformation, severe boiler explosion occurred.
6 tons of railcraft steam boiler maintenance procedures introduced 1, boiler during operation should pay attention to the following points: (1) does not allow pressurized combustion furnace flame, or easy to damage the door, watching the fire door and unsafe. (2) should be regularly blower, fan, electric water pump fuel. (3) It should be noted arch brick without loss, with or without overflow wall furnace fire phenomenon, identify problems and timely repair, repair shutdown if necessary. The bottom surface (4) shall boiler water to prevent corrosion of the base. (5) The class filter at least once to open check. 2, 2 a boiler operation three weeks should carry out a check. (L) before opening the flue, if smoke tube fouling should be removed, such as less fouling or non-fouling, cleaning time may be the Director, opened once a month, if still no fouling extended 2-3 May start time, checking after each turn, must be locked, shall not leak smoke. (2) Open once each class cleaning door, cleared out the gray tone, without fouling or fill extend cleaning time, according to the actual situation in the hands of fireman, and explore the experience. (3) water gauge, valves, piping, flanges, etc. should be repaired as steam leakage. (4) boiler 2 to 3 months, to the water wall, pipe and be cleared of soot ignition face. Run 3 to 6 months after the shutdown should be all inspection and maintenance. (5) inside and outside of the boiler inspection, such as the partial pressure weld steel corrosion; If it is found serious deficiencies should be repaired, if the defect can not leave shutdown repair, found suspicious, but does not affect when production safety, records should be made for reference during processing. (6) can be checked and the coated portion of the boiler water to prevent corrosion paint. (7) if necessary insulation furnace wall outer casing removed to provide a thorough examination of the prior seriously damaged portion, only after continued use must be rehabilitated, checked and repaired while the person filling the case of the present security technology registration boiler. (8) housing the heat insulation layer (outer sheath), a paint duct at least a year. (9) Maintenance of long-term without the boiler, dry and wet, dry application shutdown more than a month, the following month shutdown can be used wet maintenance method.
Brewery railcraft steam boiler water treatment measures which at present, is a boiler steam boiler brewery commonly used for disinfection, medicine and other suffering. For the pharmaceutical industry this particular area is concerned, the requirements for steam and hot water level is relatively high. This step treatment that becomes more important, the following small series bring you a quick look at the water treatment methods, results and so on. Simply put, the purpose of boiler water treatment is provided by the addition of certain equipment, such as impurity removal of boiler water softening treatment, prevention of boiler corrosion or fouling occurs, in order to ensure good quality of steam, but also conducive to the boiler thermal efficiency, in terms of the brewery, which is more in need. Methods brewery steam boiler water treatment: (1) In general, when the boiler water treatment, taking into account their own situation, and the situation boiler boilers and other areas. Vapor pressure for evaporation and a small part of the boiler to be equipped with oxygen equipment in accordance with the actual situation, while the outer pot for the chemical treatment. (2) If the local water contains more impurities, water should be filtered before or during precipitation, so as to avoid blockage of the boiler water treatment equipment, water treatment effect is low, the efficiency is not high. (3) In addition, we should note that, during the boiler water treatment equipment selection, cut not covet low price, ease of use and other considerations while ignoring the quality of the equipment, so not only can not be effective treatment, but can also result in energy waste and reduce the life of the boiler. You know, for a long time corrosion and fouling it is easy to make low thermal efficiency of boilers, boiler unnecessarily severe accident. In short, this brewery steam quality and environmental protection fields of high, must be strictly water treatment steps, in accordance with a qualified water treatment methods and standards.
Under the guidance of our customers professional and technical personnel, the full solution of the fast square excellent products and brand strength, our company is very interested in several steam products, finalized the purchase of three 1.25MPa, respectively 2 tons of steam , 4,15 (WNS2 / 4 / 15-1.25-YQ) and two 1.6MPa, steam tons the amount of 4,10 (WNS4 / 10-1.6-YQ) integrated condensing gas boiler steam, and hope to establish with our company long term cooperative relations.
