wholesale boiler steel pipe
Hot water wholesale boiler steel pipe blowdown should pay attention to what matters hot water boiler in use for some time, due to multiple cycles of water in the pipeline, will have some dirt, in order to ensure the normal use of the boiler, the need for timely discharge. Hot water boiler blowdown, to note the following considerations. 1. Hot water boilers, prior to the sewage work, first the boiler water level is adjusted in the talk state is slightly above the normal water line, there should be no flow of sound in the outfall, sewage pipes outside the hand touch drain valve, if feel a higher temperature, then drain valve leaks circumstances, should be checked, identify the cause, and then during the elimination. 2. The hot water boiler blowdown during work, to be performed after the fire boiler pressure, the sewage or low load, because of recycling of water within the boiler at this time is relatively slow, the dirt accumulation inside the tubes easily, sewage effect will be better, while the boiler output will not be affected. 3. The operation of the sewage water in the boiler should be carried out in the short state, i.e. each discharge interval is short, repeated, it is a good soil to quickly turn sewage outlets, can be discharged Concentration. 4. During hot water boiler blowdown during the work, we should always pay attention to the water level changes, to prevent sewage work caused by water shortages in the furnace, the relevant responsible persons banned from leaving the scene. 5. The hot water boiler blowdown work itself would require frequent, uniformity of sewage, sewage class at least once in a boiler, and how root sewage, must be provided for each take turns sewage outfall work, If only a portion of which the sewage outfall, while another portion is not performed if the sewage, so that the part of the outfall blocked, leading to destruction of the water cycle, the worst case occurs tube rupture. When more than one boiler and when used simultaneously with a row of sewage mains, sewage pipes and on each boiler and no check valve, in this case, strictly prohibited while sewage, to prevent sewage water back into the other the boiler.
Various protection functions ensure the wholesale boiler steel pipe’s safe and reliable operation.
Equipped burner with excellent automatic control to realize full automatic performance.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type wholesale boiler steel pipe paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
Hazardous industrial wholesale boiler steel pipe scale industrial boilers which produce harmful industrial boiler scale which harm scale which temperature heating surface (1) endanger safe operation of the boiler, shorten the life of the boiler water temperature is generally higher than the furnace 6 ~ about 10 ℃, but the presence of scale, leading to sharp increase in the temperature of the heating surface, will creep to overheating, increased corrosion of high temperature oxidation processes may cause metal deformation, bulge, or even rupture blasting; fouling layer of acidic or alkaline substances, it is easy to corrosion of metal equipment and shorten its life, seriously affecting the safe and stable operation of the boiler. (2) reducing the thermal efficiency, increased fuel consumption due to the thermal conductivity of only a few one-tenth scale steel, boiler heating surface scum resulting in reduced thermal efficiency, resulting in increased fuel usage. The data show that, when a surface junction raw 1mm scale, a 10% increase in fuel consumption; when the scale thickness of 3mm, about 25% increase in fuel consumption. Increased fuel consumption, will increase air pollution, which is the current energy conservation is contrary. (3) increased maintenance costs, environmental pollution if the boiler frequently produce large scale, in order to ensure its safe and stable operation of cost-effective, it would need to take timely and effective measures to deal with, or mechanical descaling, or chemical cleaning, a lot of manpower and resources will increase loss, produce a variety of charges. In particular, chemical cleaning, will produce a large basic or acidic wastewater, improper handling will cause serious environmental pollution.
