large boiler grinding and forging factory

Why do some treated water softening, water or exceeding it?

In general, some of the water from the boiler to the well water, river water or tap water, which contains large amounts of calcium and magnesium ions in water, the water, if not treated, is heated directly in the boiler, the boiler will cause precipitate adhered to the wall or elbow, reduce the heat transfer efficiency of the boiler, the boiler will result in localized uneven heating affect of the boiler and even reduce the life of the boiler.

Boiler long time, some failures will be exposed, indicating reduction in service life day by day. Many users in the choice of natural gas large boiler grinding and forging factory, the boiler will also consider how many years would be able to use, because it is directly related to the vital interests of users. So life natural gas boiler in the end is how long? Check out our natural gas boiler factory in Henan party soon introduce it to everyone.

20th Meeting of the Standing Committee of People's Congress of the fourth Jinzhong City, approved the Thirteenth People's Congress Standing Committee of Shanxi Province, the seventh meeting since January 1, 2019 the formal implementation of the "Jinzhong City coal pollution prevention and control regulations "(the" Ordinance ").

1, Municipal People's Government shall determine the total amount of coal required control objectives, the development of coal-fired reduction and clean energy transformation plan and organize the implementation, reduce the proportion of coal in primary energy consumption structure in accordance with the requirements of the provincial government and city environmental protection.

2, Municipal People's Government shall designate built-up area for the city ban on coal zone and gradually extended to improve the quality of atmospheric environment on request. Counties (cities, districts) need to improve the people's government should ban on coal zone demarcated according to the ambient air quality.

May, ban coal-fired power plant area, central heating stations and raw coal units shall establish a coal purchase and sale of its products archives management, and self-purchase contract is signed or change within fifteen days, the number of coal procurement and information submitted to the seat of county government department in charge of energy.

6, city and county (city, district) people's government should promote the local conditions of the administrative regions of central heating, coal to electricity, coal gas and other clean energy alternative to coal-fired work. Encourage towns, rural areas to promote the use of clean energy living stove.

9, city and county (city, district) people's government should strengthen the management of civil bulk coal regions other than coal ban areas, to determine the clean coal supply companies, establish and improve civil cleaner fuels coal procurement, storage, supply mechanism to protect the clean coal supply.

10, city and county (city, district) people's government market supervision and management departments should be included in the annual coal-fired coal sampling plans to strengthen quality supervision and inspection, and to the public inspection results.

11, coal-fired power plants, district heating stations and boiler units to use raw coal output and single kiln production process should be in line with national standards and local regulations or policies. Any unit or individual may manufacture, import, sale and use do not meet environmental protection standards of boilers, furnaces.

12, supporting the construction of coal-fired units should use air pollution control equipment and facilities to maintain normal and stable operation, pollutant discharge should meet the standards set by the state and local levels. Encourage the use of coal-fired units to implement ultra-low emissions transformation in accordance with the requirements of environmental protection.

You have to know the large boiler grinding and forging factory energy consumption (main steam temperature solve the problem) main steam temperature problem-solving measures 1 boiler operation 1.1AGC control measures to closely monitor fluctuations in the amount of coal, the fuel surge slashed the emergence of the subject Save heated conditioned manual intervention. 1.2 artificially adjusting the load, increase or decrease the amount of coal can not be too large. 1.3 adjusted to optimize the combustion tests, the optimum value of oxygen boiler, the boiler properly regulate the amount of oxygen. 1.4 put into operation the burner adjustment mode, by adjusting ensure that the main steam temperature combustion boiler. 1.5 normal temperature control into the main steam boiler. 1.6 intense monitoring segments superheater steam temperature, steam temperature adjustment for adjusting so that ground, the fine reduced spray desuperheater water, controlling the main steam temperature. 1.7 Test mastered by pulverizing system operation changes the influence of the main steam temperature, analyze the causes and make predictable adjustments. 1.8 rational for sootblowing heating surface. 1.9 stratified fuel amount adjustment, reasonable control center of the flame, adjust a secondary air ratio, the excess air ratio changing, if necessary. 2 routine maintenance and testing 2.1 combustion adjustment experiment to determine the best mode of operation and control parameters boilers. 2.2 improve the quality of automatically adjusting the main steam temperature. 2.3 to detect and analyze the reasons offset the center of the furnace flame occurs, and take specific measures. 3 3.1 eliminate downtime desuperheating water leak phenomenon each valve. 3.2 heating surface power, clean fouling. 3.3 dredge preheater, treatment of flue leakage. 4 4.1 pairs of respective transformation means within the steam separator drum for cleaning up, and remove related defects. 4.2 pairs of waterwall, economizer, reheater, superheater tube cutting, scaling internal corrosion test cases. 4.3 heating surface slagging, fouling cleaning. 4.4 due to equipment problems reheat steam parameters less than the design value, or burner heating surface transformation.
