boiler water tubs bending work

Corrosion boiler water tubs bending work water wall Analysis and Solution: For boilers, corrosion will directly or indirectly affect the life of the boiler. One of the main factors of high temperature corrosion of boiler water wall is seriously affecting the safe operation of the unit, solve the problem of water wall high temperature corrosion of boiler operation has a good long-term stability of the practical benefits. Many membrane wall by the rolled boiler water wall tube spot welding the fins to each other, making a combination heating surface sealing, can improve the air tightness of the furnace, reduced leakage, but also better protecting the furnace wall, the furnace wall reduce the weight, simplifying the structure.

Natural gas industrial boiler water tubs bending works produce condensate water hazards natural gas industrial boilers produce condensate water hazards natural gas industrial boilers produce condensate water hazards 1, the corrosion of condensate water boiler heating surface major harm to the natural gas industrial boilers is the corrosive effect on the heating surface of the boiler. Condensate corrosion WNS rear of the boiler heating surface of the bottom of the tube focus, mainly iron oxide corrosion products. Condensate corrosion can cause intense side wall thinning, strength weakened. (1) condensation with the flue gas evolution corrosion, some CO2 is dissolved in the condensed water, CO2 generated in case of weak electrolyte H2O H2CO3, ionized hydrogen ions, so that a weak acid condensate, and another part of the nitrogen oxides and containing a very small amount of sulfur dioxide dissolved in the condensate, enhances the acidity of the condensate, the pH of the condensed water as in table 1 were lower than the position of the drum 4.3. iron hydrogen evolution corrosion can occur in the acidic solution, and the strong acid, the reaction The faster rate. (2) Since the oxygen etching gas during combustion boiler need to ensure a certain air ratio, combustion flue gas contains oxygen. When the steam condenses, some oxygen will be dissolved in the condensed water, causing corrosion of the metal heating surface of the oxygen. 2, when the cross-sectional area to reduce the flue gas flow type gas boiler industrial boilers operate at low load, the heated surface of the flue gas, the condensed water gathered in the smoke tube, the resulting corrosion products accumulate in the bottom of the tube, even clogging of the pipe part, thus reducing the flow area of ​​the flue gas, the flue gas resistance increases, and increase in power consumption of the blower. 3, the furnace temperature is lowered, damage to the burner within the examination of natural gas in industrial boilers, often find a certain amount of condensed water. We found condensate discharge tube boiler such severe congestion, resulting in condensed water in the lower furnace does not discharge, and refluxed for aggregation. When the boiler is started, the heat accumulated in the furnace absorbs the condensed water and evaporated fuel combustion, thereby reducing the furnace temperature. If the furnace condensate accumulated too much, and even dipped into the burner, causing damage to the burner. Suddenly turn off the boiler, the boiler does not start, because the burner too much condensation water immersion, affecting the safe operation of the boiler. 4. Effect of boiler condensate generated on the heat sealing material penetrates into the sealing material of the boiler insulation, the point of the arrow indicated gas tank gas boiler WNS industrial boilers. Sealing condensed water immersion insulation material for a long time, the insulation effect will be weakened or even physical damage, increased heat loss. Meanwhile, the condensed water will make the sealing material deformation aging, sealing capability weakened, leading to a certain amount of flue gas emissions, which not only be dangerous, can also cause a certain amount of heat loss.

Fangkui Boiler aims to "warm the world", and we provide target customers worldwide with boiler water tubs bending work equipment and service guidance to meet their needs. At present, we have provided boiler equipment and solutions for customers in more than 80 countries and regions, including Russia and Bangladesh, to promote the production efficiency of customer enterprises.

Buy electric boiler water tubs bending work products 1. Mistakes do not understand the relative performance of electric boiler products, blind purchase. Generally electric boiler electric heating device is not a so-called electric cooking equipment, but is connected radiators and floor heating equipment for heating. So if we need home heating equipment, then we can understand more about electric boiler products. 2. Mistakes product without prior consultation used household electric boiler, casually buy. Many users buy electric boilers after the simple understanding of electric boilers directly purchase, no more asking people who used electric boiler, this case is the use of electric boiler can not be a case of direct purchase. 3. The lack of understanding of electric boiler brand. I do not know what brand of electric boiler is better, this calls boiler is a new product on the market and there is no fixed pattern, there is no example of a good brand, so there are many brands of electric boilers are mixed, according to Xiao Bian understand , the relatively good domestic electric boilers have the Austrian Korea, Shante, Hua and so on. 4. The lack of understanding of the important parameters and electrical power consumption of the boiler. Power consumption of electric boiler this calculation: if we live in a house of 100 square meters, heating an area of ​​100 square meters, then choose electric boiler size of about 10kw, and the daily power consumption is half of the area is 50 degrees. The electric boiler does not pay attention to after-sales service. If you purchase a regular electric boiler, it is normal for aftermarket replacement a year, so that these must pay attention to after-sales service in the purchase of electric boiler.

The HMT Boiler Tube Bender Fits Boiler Industry Needs

HMT builds a booster type boiler tube bender, which forms tight radius thick wall tubes used in the boiler industry. We manufacture these heavy-duty boiler tube bender machines equipped with a clamping device, which locks the tube into the pressure die and allows the tube to be forced (boosted) into the bend die thus reducing wall thinning and ovality.

Apr 30, 2006 · A water tube of this type is certainly not for everybody Due to the fuel used (wood) and the modest water volume, it calls for a lot of attention during operation. After shutting off the main steam valve at full power, the safety valve would be activated in just a couple of minutes if no measures are taken to prevent it.

Rotary Draw Bending. For precision work, rotary draw bending dominates the tube bending landscape, especially for those applications involving tight radiisometimes down to a CLR thats just 0.7 times the tube OD (or as tube processors call it, less than 1×D). This process gives you maximum control over wall thinning and ovality.

Model Watertube Boiler

I have been slowly reaming all the boiler tube holes in the drums for the required entry angles. It is a lot of work, making tubes, then mocking-up portions of the boiler against a drawing - just to determine these angles. The incessant hand reaming doesn't do much for my shoulder and back muscles either.

Condensate pipe - DIY Plumbing

Condensate pipe overview. Water vapour from the combustion process is channelled through the boiler until so much heat is drawn out of it, it condenses back into water. (In a non-condensing boiler, this process is absent. The hot gases are simply expelled out of the flue and the heat is wasted.)
