In the process of using steam hot water boiler industrial cheap 20t vietnam, when the water containing impurities enters the boiler, with the continuous evaporation and concentration of water, the concentration of impurities in the water increases gradually. When the boiler reaches a certain limit, it will bring some adverse effects to the boiler. The way to deal with this situation is to discharge the boiler, so what matters need to be paid attention to when discharging the boiler? The following is a detailed introduction for everyone. (1) before discharge, the boiler water level shall be adjusted slightly above the normal water level. When discharging water, closely monitor the water level to prevent gas-fired boilers from running short of water as a result of pollution discharge. After sewerage, there can be no more sound of water flowing in the pipe. After a period of time, then touch with your hand. Sewerage pipe, if the feeling temperature is high, indicate sewage valve has seal condition, must find out the reason to be eliminated. (2) according to the principle of diligence, less row, and uniform arrangement, each shift should be discharged at least once. When a gas-fired boiler has several sewage pipes at the same time, all sewage pipes should be discharged in turn. If only one part is discharged and no other part is discharged for a long time, the water quality of the furnace will be reduced or some sewage pipes will be blocked. It can even break the water cycle and have a pipe explosion. When multiple boilers use one main drainage pipe at the same time, it is prohibited to discharge water simultaneously to prevent the sewage from flowing back to the adjacent boiler. (3) Sewerage shall be discharged after the boiler is pressed or at a low load When, at this time boiler water circulation is slow, the slag scale is easy to accumulate, the discharge effect is good. (4) the discharge operation of gas-fired boiler should be short and discontinuous, that is to say, after each discharge valve is opened, it should be closed again. So repeated several times, rely on suction to make the slag quickly confluence to the sewage outlet, and then centralize the discharge. If the first discharge time is too long, the concentration of slag scale in the pot water is first high and then low, which not only reduces the discharge effect, but also increases the amount of sewage discharge, thus causing the local water circulation to fall. (5) the adjustment operation of the surface discharge is realized by the opening of the regulating valve, and the value is determined by the test results of the water quality of the pot. It is possible to discharge steam hot water boiler on a regular basis. In order to make the boiler water quality meet the standard requirements, maintain good water quality, slow down or prevent scale formation, ensure the use of steam hot water boiler.

Shanxi Province to continue to improve and protect the environment, prevention of air pollution, with "Environmental Protection Law of People's Republic of China", "People's Republic of China Air Pollution Prevention Law" and other relevant laws, introduced the "Shanxi Atmospheric Pollution Prevention Act" ((hereinafter referred to as " regulations ").

"Regulation" is mentioned, Shanxi coal consumption will implement the total control system, and gradually adjust the energy structure, reduce the proportion of coal in primary energy consumption. Provincial People's Government will work with the energy department in charge of relevant departments, according to the needs of economic development, social and environmental carrying capacity of resources, the development of the region's total coal consumption control target.

First, governments at all levels to limit sulfur points, high ash coal mining. New coal mines should simultaneously supporting the construction of coal washing facilities, so that the coal sulfur content, ash content meet the required standards. Have been built in addition to the mining of coal mine belonging to low-sulfur, low-ash or coal-fired power plants have been in accordance with the requirements of discharge standards do not need washing outside, it should be a deadline for the completion of supporting coal washing facilities. When coal, gangue, coal cinder, coal ash and other materials, should take fire and dust prevention measures to prevent air pollution.

Second, the coal-fired power companies, coking, and other steel companies use coal shall clean production processes, supporting construction dust removal, desulfurization, denitrification device to reduce the generation and emission of atmospheric pollutants.

Third, the city government should promote cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion scattered coal-fired heating boilers, central heating pipe network coverage prior to the completion of use of scattered coal-fired and coal-fired heating boilers have been built can not discharge standards heating boilers, should be demolished within the prescribed period the city government.

Fourth, the Municipal People's Government shall be divided into districts to improve the quality of atmospheric environment in accordance with requirements, it will be designated urban area to ban coal region, and gradually expand. County (city, district) people's government can scoping ban on coal zone in accordance with the actual situation. Delineation ban on coal zone should consider the needs of life of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.

Fifth, governments at all levels should strengthen the management of civil bulk coal. Prohibit the sale, does not meet the civil standard of quality coal for coal, lignite ban, coal washing, slime and other low-quality coal use low-quality coal as a civilian.

Condensing boiler industrial cheap 20t vietnam flue gas heat recovery, so that the boiler efficiency is improved, but not all areas are suitable for condensing boilers.

7, the inner pipe severe fouling or debris there, the destruction of the water cycle.

Second, the method of preventing gas hot water boiler "vaporized" in

1, to strengthen the maintenance and repair work on the boiler, especially water pump transmission parts, bearings and other parts must ensure its good performance.

2, the process of boiler operation, the fireman who step up inspections, and inspections must be in place, seeing, ears, hands touch, comprehensive see whether the boiler appears unusual circumstances, whether it is normal to hear the sound, touch mechanical temperature is too high, vibration Is it big.

3, sensitive and effective monitoring systems, safety accessories intact, sensitive and accurate, with a non-normal to stop the pump alarms and interlocks, should be immediately filled and no.
