China seamless steel boiler tube manufacturers

Interlocking means low water, the water level should be below a prescribed value blower, Fan, grate reducer motor stops running; security level lower than the low water level, the water table as a white glass (plate); rinsing water table, determined small gas steam china seamless steel boiler tube manufacturers is full of water and mild or severe full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slightly open the drain valve ,, full of water, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.

For a long time, the domestic industrial production are supplied by the coal-fired industrial china seamless steel boiler tube manufacturerss, although the use of such boilers to the rapid economic development has brought great power support, but coal burning will produce large amounts of sulfur oxides, nitrogen oxides , dust and other polluting gases, leading to serious deterioration of haze and air.

Processing gas china seamless steel boiler tube manufacturers maintenance which issue large scale potential harm to the boiler should be noted that, while it can be achieved by two methods outside the boiler water treatment and boiler water treatment, to reduce the scale of production and removal of scale, reduce boiler scale potential hazards. 1, the outer pot + water ---- lime soda softening of this method for a variety of boiler. Currently a reliable treatment effect of the outer pot + soda lime softening, lime is added an appropriate amount of soda ash and the softening has been clarified water to the object. There are two kinds of hot and cold process methods lime and soda softening. Cold process is carried out at room temperature, the residue in water hardness to 1.5 to 2 mEq / l. Calorimetry is heated to a temperature of 20 ~ 80 ℃, residual water hardness to 0.3 to 0.4 meq / liter. Thus, thermal method should be adopted to improve the softening effect. Ion exchange softening mainly by sodium ion exchange exchange resin softening treatment. Due to the strong exchange resin adsorption capacity, capable of free water in the calcium and magnesium ion adsorption, so that the hardness of the boiler feed water meet the eligibility criteria. Ion exchange agents are inorganic and organic two categories. Inorganic surface exchange exchange resin only, a softening effect is poor, less use. Characteristics of the organic-exchange resin is a particulate core loose structure, while the exchange reaction may be carried out on the particle surface and an interior, good softening effect, it is used more. 2, the pot water added Chemicals ---- This method is mainly added to the boiler water chemicals, calcium scale formation in boiler water, magnesium loose sediment formed, then the method will sediment discharge sewage out of the furnace, serve to prevent boiler scaling effect (or decrease). The syrup furnace process generally used for compact low fire tube boiler. Pot of water treatment commonly used drugs are: trisodium phosphate, sodium carbonate (soda ash), sodium hydroxide (caustic soda, also known as caustic soda) and organic colloids (tannin) and so on. When dosing, the various drugs will first be formulated as a solution, and then added to the boiler. Trisodium phosphate concentration of the solution is usually 5 to 8% concentration of the solution is less than 5% of sodium carbonate, sodium hydroxide concentration of not more than 1 to 2%. Dosing methods have regular and continuous dosing two kinds. Dosing regularly performed mainly by gallipot dosing; continuous dosing of the water supply device before the drug is added to the water continuously. For steam boiler, preferably a continuous dosing method, so that the furnace can maintain a uniform drug solution. Where the use of pot for water treatment, boiler blowdown should be strengthened, so that sludge, dirt and other baked row already formed outside, receive better results. Zheng pot is equipped with a computer-controlled automatic boiler water softener (e.g. Tuzu, Fleck). Its advantage is the high degree of automation exchange of large capacity, low salt consumption, low power consumption, reasonable structure, easy to install, reliable performance, completely avoid human interference, lightweight package of equipment structure, strong corrosion, also possible to control part of a conventional manual device with automated to be modified.
