Oil-fired boiler maintenance methods "" A lot of companies because after the purchase of oil-fired boilers, Careless maintenance process, with the result that the useful life of oil-fired boiler is greatly reduced. So how should it be maintenance of the oil-fired boiler? The following article gives you a detailed analysis. After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler. Stop oil-fired boiler more than a month, maintenance of law should be dry, wet maintenance shutdown method can be used the following month. To schedule the maintenance period Microflame oven, schedule the water cycle, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Periodic inspection outage before the oil-fired boiler furnace, should be prepared to work the following three aspects: (1) review the registration technical dossier furnace boiler and boiler furnace usage understand. In order to fuel the transformation within the furnace boiler external inspection be aware, the general need to understand: the transformation of the electric furnace boiler design, manufacture, installation; boiler furnace revamping; boiler furnace use history and usage; boiler furnace water treatment case ; boiler performance and other rules and regulations. (2) Check before shutdown preparation. First, with the production schedule maintenance shutdown date, and then let the transformation of the normal furnace boiler shutdown program shutdown, but slowly disheartened. Injecting cooling method may be employed downcast water, replacing the water cooled furnace and the furnace into line ventilation cooling. When the boiler water temperature was reduced to 70 ~ 80 ℃, before drainage. Open all doors hole. When the door opened, to prevent warm water, steam jet man suddenly burns. Corresponding to the passage blocked pipe on the transformation test furnace boiler steam, water supply, sewage and other pipes and other run in the transformation of the electric furnace boiler. Blocked with shutter have sufficient strength to avoid being broken drum high pressure medium. To clear the blocking position is indicated. And other operational boiler furnace flue should be communicated reliably cut off. Also to clear the transformation of furnace soot and scale boiler by warm surface. (3) test preparation tools and lighting. In order to ensure the smooth entry inspection, the inspector should prepare the necessary equipment, tools, measuring tools and safe and reliable lighting devices.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
Gas boiler cook stove Note: As the boiler equipment kinetic energy sources in the manufacturing, transportation, installation and maintenance process will bring oil and other impurities, persist in the boiler, it will not only clog water pipes, deteriorating the quality of steam, but also will reduce the heat transfer effect, the heating surface prone to overheating cause burn. Therefore, for removing impurities boiling out this step, the stable operation of the boiler is an integral part.
Xiao Bian now introduce gas steam boiler china industrial boiler price classification accuracy and precision hydraulic machine Henan fast boiler's steam boiler gas and hydraulic classification of a gas steam boiler By Type 1, an industrial gas steam boiler: heating and for industrial production and so on. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.Free Chat
