pengolahan air umpan boiler

As a leader in the fast side condensing gas pengolahan air umpan boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback

The reason industrial pengolahan air umpan boiler explosion and the cause of industrial boiler explosion hazards and hazards? For chemical plant before use, it must be to raise awareness of prevention. So as to avoid unnecessary losses to yourself. During boiler operation, the pressure exceeds a predetermined pressure to certain parts of elements, the thin portion will suddenly break, crack out immediately stored in the pot will be full of steam. In an instant, a pressure drop equal to pot the external atmosphere. At this time, since the momentum intense, so that part of violent boiling pot filled with water, the expansion, a small part of the whole pot steam also will be warmed, a pressure rises again, further expansion gap. Because full of water and steam in the rapid expansion of one-tenth to twenty second, when gunpowder exploded just as the rapid expansion of the gas, they become a powerful shock wave, with great destructive power. When the boiler explosion, due to the bursting of steam and water has a very high speed, or when the front portion in contact with air, will have a huge reaction, or moves off the boiler in the direction of the reaction force, rolling. Vertical boiler mainly in the blast site and calf ring potshell welding, explosion, steam, the water jet, and then pushed up Boiler fly. Horizontal boiler explosion member burners or more in the weld of the tube plate and the drum, the drum in contact with the combustion. When the explosion occurred, steam and water splashing forward or backward or downward, parallel to the fly boiler, boiler and rolling at the scene. A boiler explosion released energy is only a small fraction of the steel sheet to tear the boiler, in addition to steam and debris and the pipes, valves and the valve body is connected to the boiler, the energy transfer most of the other great shock wave in air, causing a large number of peripherals, badly damaged buildings, as well as the formation of casualties.

How natural gas pengolahan air umpan boiler cleaning? Alkali cooking cleaning method: gas-fired cooking alkaline cleaning method descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, and therefore difficult to remove with hydrochloric acid for scale before acid pickling may be treated with a base to conduct a cooking method. Alkali cooking method is simple, relatively small side effects. The disadvantage is a long time cooking oven, more reagent consumption, and poor results. Descaling pickling method: gas boiler descaling pickling process using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. This can eliminate the acid liquid natural gas boiler scale (scale except when nitrate, hydrofluoric acid to be added), and very little corrosion in the boiler. Descaling pickling has dissolved, exfoliation and slack action. Mechanical descaling method: When a loose scale and slag within the gas boiler, the boiler shutdown after cooling, let go of boiler water, rinse with water after, to use flat shovel, wire brushes, and motorized milling tube is descaled . This method is relatively simple, the scale used for simple, small boilers. However, labor-intensive, ineffective cleaning, easy to damage the boiler.

Boiler happen "water hammer" how to deal with: "water hammer" is a major factor affecting the operating life of the pengolahan air umpan boiler, the main causes is the boiler pressure pipeline, due to the influence of some external factors (such as valves suddenly closed, water pump suddenly stopped, etc. ) so that the water flow rate suddenly changed significantly, so there is the risk of water hammer phenomenon.
