In mid-April, Hohhot, Inner Mongolia issued a notice (hereinafter referred to as the "Program"), "Hohhot tackling air pollution control plan" (2018-2020), the "plan" to win tough fight pollution prevention, to promote air pollution control, as the city to create a pleasant living environment for the development of the measures.

For air pollution control, "plan" set goals. As of 2020, Hohhot air quality more than two days ratio reached 83.8%, fine particles (of PM2.5) concentration of 35 micrograms / cubic meter. Wherein, 2018 Hohhot air quality objectives: good percentage of days to reach 79.5%, fine particles (of PM2.5) concentration of 39.2 micrograms / cubic meter.

Since 2017 to enter the heating season, Hohhot is the air quality continues to improve, has introduced the autumn and winter air pollution in Hohhot comprehensive reform program "," Hohhot 2017--2018 autumn and winter special inspection of comprehensive air pollution control program of work of law enforcement. " "Hohhot 2017--2018 autumn and winter air pollution in the comprehensive management of supervision and inspection plan", "Hohhot environmental Protection Agency checks on the issuance of the work program of the winter heating enterprises notification", "Hohhot City people's government on the issuance of residential heating clean alternative , "and other series of notifications. Key measures to coal-fired boilers for heating and bulk coal governance.

Second, the city's coal-fired boiler coal yard, residue field to achieve full closure transformation; more than 20 tons of steam / h coal-fired boilers have been installed pollution-line monitoring equipment, and networking with the Municipal Environmental Protection Bureau, established a 24-hour monitoring system.

Through the above measures, Hohhot air quality improved significantly compared to the same period. January 1, 2018 --3 17, good days Hohhot total 66 days, an increase of 4 days last year. Sulfur dioxide concentrations decreased 40.7% over last year, PM2.5 concentration decreased by 20% over the same period last year.

According to (2018-2020) spiritual requirements "Hohhot tackling air pollution control plan", 2018, the Board will eliminate 35 tons of steam utility / h coal-fired boiler room 11 - 15, involves heating an area of ​​3.872 million square meters. Currently the demolition and integration of clean energy and the transformation is complete, out of the task have been put in place, we have been completed out of eight coal-fired boilers and boiler room of the grid work, removal of nine coal-fired boilers (grid yet dismantled three, to electricity yet dismantled three), and has been able to "break two three clear", the remaining boilers will be completed by the end eliminated.

It describes three kinds of hot water seamless boiler steel tube and understanding of: the type of boiler, the following will be involved, as this is mainly a hot water boiler, so for us, but also by learning new knowledge, to learn more about the boiler, and make yourself a lot of benefit. Therefore, I hope you take seriously and carry on, do not give in vain wasted. 1. The hot water boiler drum type, which is a kind of boiler? Hot water boiler drum type, its initial stage is to transform steam boilers obtained. Its boiler water, natural circulation is carried out in the boiler. However, in order to ensure safe and reliable boiler water circulation, so in height, there is a certain requirement. Thereby resulting in volume, but also an increase in the. 2. hot water boiler with natural circulation if it is, then what is the specific arrangement there? Hot water boiler, if it uses natural circulation, then the particular arrangement, is as follows: the boiler inlet and outlet, are taken over from the top of the drum, by the water introduced into the water prior to dispensing tube side and lower header. Through the waterwall tubes, for heating rises. Further, the front end of the drum, is also provided with impermeable sheet, its main function, the lower half of the drum cross section cut off points.

Diagnosis: case of an electric steam seamless boiler steel tube can occur when water vapor through the use of electric boilers electrical energy, which is converted into heat, and then the converted electric heating system of the boiler steam output having a certain thermal energy outwardly. Many users will find when operating electric steam boiler, the boiler will not appear abnormal ring, the water flow is abnormal happens, but do not know where in the cause. In this paper, electric steam boiler in the water shortage, what would happen, expand and talk. In general, when there are electric steam boiler explosion that, at the door began to steam out, it shows electric steam boiler water shortage is very serious and should be carried out immediately pay, or they may be dangerous. Mainly as electric steam boiler water level has been cut siren sounded the alarm sound level below the safety line. At this performance should let dry electric steam boilers stop running, and then the alarm sound off, then add the water in the electric steam boiler above the water line, electric steam boiler restart just fine. Electric steam boiler exhaust smoke temperature rises, then it should be because the pipeline rupture caused by electric steam boiler, the solution is to pipe water shortage caused by electric steam boilers quickly repaired, or to replace a new pipeline. Boiler water can be divided into two cases, one slight lack of water, one serious water shortages. When the water level in the water level below the specified minimum but can see or can not see the water level has instead of "water law called" waters, could see the water level, water shortages were classified as minor. As the water level is not visible, but still a serious lack of water when the water level not seen as "Water Act called" waters. Program called the water: first turn on the water faucet is turned on, turn off the steam cock, rinse water connecting pipe parts, then slowly turn on the water tap is closed, pay attention to whether the water into the inner man boiler water level gauge, this method is referred to as "called Water Act." The reason water; the loss of the water level control light; dereliction of duty fireman; water supply system failure, such as lack of water pressure, no water fill, water level indicator is incorrect and false water level; boiler blowdown valve may be caused by a leak caused by lax boiler water. Boiler water should be promptly find the cause and correct treatment, improper handling can cause serious accidents. Water treatment: The water level is just below the normal level. But still we see, you can restore the normal water level should be strengthened and rinse water level in Sheung Shui. Check the water supply, water and other systems, for damage and leakage and other problems, severe cases should be treated shutdown. When the use of "water law called" flushing water level and other treatment still do not see the water level, severe water shortages may occur accident, should immediately shutdown, quickly turn off, find out why. In this case, the operator should remain sober and avoid confusion, non-Sheung Shui to the boiler, eager to avoid the possibility of replenishment and cause serious explosion in the boiler drum water boiled.

Now let's talk about the solution. It is necessary to find out the reasons for treating the problem, cut off all discharge cages, block all running, risking, dripping, leaking, increasing the automatic exhaust valve of the system, strictly manage the system, and make the replenishment rate run up to the standard. A small amount of supplemental water is inevitable, but the quality of replenishment water, preferably deaerated water. The seamless boiler steel tube water heating alone can make use of the waste heat from the tail flue to replenish the proper amount of sodium phosphate and sodium sulfite into the boiler at the same time, which is beneficial and harmless to the boiler. Strictly control the PH value of the furnace water, and test the PH value on a regular basis.

Difference between hot and cold seamless tube

Seamless steel tube has a hollow section, a large number of which are used for conveying fluid, such as crude oil, natural gas, coal gas, water and some solid materials, etc. Compared with solid round steel, when the torsional strength is same, the weight of the seamless steel pipe is relatively light, so it is a kind of economical steel, which is widely used in manufacture oil tubular goods and mechanical parts.
