Henan gas why the surface corrosion of industrial boiler happens water level adjusting operation when the object is to ensure adjustment of water balance, i.e., equal to the amount of main steam to water, to prevent excessive fluctuations in the water level. Level is too low, it may cause the downcomer with gas, the circulating flow of water head pressure is reduced, the safety of the natural water cycle is reduced, if the gas boiler feedwater Henan interrupt continuous operation, it might appear in the tens of seconds "Griddle." Henan gas boiler water level is too high, water separation space height will result in reduced steam with water, steam quality deterioration (mechanical vapor carrying the increase will result in salt content), there will be serious when the bubble filled with water, resulting in a large number of steam with water, high salt content of the steam superheater severe fouling, resulting in over-temperature burst pipe wall, can also cause water hammer and steam turbine main steam pipe, the impact of safe and economic operation of the device. Also, keep the balance of water and evaporation, prevent water shortages (or full of water) accident. Boiler operation and regulating water flow according to the change of the load, uninterrupted by the water level of the water table supervision pot. Boiler water level should be kept at a normal water level line, and 50 to allow the fluctuations in a normal water line. In order to maintain the normal water level, the water level to be adjusted according to the load of Henan gas boiler. Henan gas boiler in the low load operation, the water level should be slightly higher than normal level, the load increases to prevent the water level drops too low; boiler high load operation, the water level should be slightly below the normal water level, the water level rises so as to reduce the load too high. In the run Henan gas boiler should pay to achieve a smooth, even, because of changes in water level will steam pressure, steam temperature fluctuate. Time and method of water supply should be appropriate. Water supply time interval is too large, too much time to the water, the steam pressure is difficult to stabilize; do not weaken the water supply when burned, which causes steam pressure drop.

Steel why the surface corrosion of industrial boiler happens which company is good now different domestic steel boiler manufacturers, contrast load, have their own strengths steel boiler performance. I do not know what the questioner judge the quality of a senior steel boiler yes. Generally if you want to choose exactly the type of company you exact steel boiler, as in the following several specifications need to be clear: a thermal efficiency steel boiler Second, the steel boiler thermal time three or four rated load of steel boiler, Categories in front of several steel boiler specification, procurement steel boiler absolutely normal unqualified, and the most sure to carefully think about failure, from several specification, can be seen a good steel boiler bad stable or not, of course, select the type of steel boiler when to find the best company to everyone, excellent characteristics of steel boiler is the most should pay attention to.

If you want to make six tons of gas steam why the surface corrosion of industrial boiler happens normal operation, it is important to note several points: 6 tons of gas steam boiler is a lot of kinetic energy equipment production and processing industry can not do without, users choose to fit their own businesses steam boiler plant, but also master the method so that the normal operation of the boiler, so as to ensure that the boiler to achieve long life.

The Effects and Economic Impact of Corrosion

2013-11-24 · The Effects and Economic Impact of Corrosion CORROSION is a natural process. Just like water flows to the lowest level, all natural processes tend toward the lowest possible energy states. Thus, for example, iron and steel have a natural tendency to com-bine with other chemical elements to return to their lowest energy states.
