Methods and characteristics of steam community water tube boiler water treatment

The steam boiler water treatment method has the boiler outside and the furnace also called the pot inside and outside the pot. Generally, for steam boilers and steam-steam boilers larger than 2t/h, the chemical water treatment outside the furnace should be adopted as far as possible, on the other hand, the steam boiler can only be treated with medicine in the furnace, but other means should be adopted to ensure the quality of water quality.

Now community water tube boiler explosion has rarely met, the greater the boiler safety measures do more the more stringent, safety, fire protection devices will be the focus of treatment. Generally small boiler accident relatively high, mainly because some manufacturers of boilers small boilers of manufacturing quality is not high, but the larger manufacturers have either a Class A boiler production qualification of manufacturers, for the safety of the boiler is controlled very strict, they will be in strict accordance with relevant state regulations production in line with standard boilers.

Hazardous industrial community water tube boiler scale industrial boilers which produce harmful industrial boiler scale which harm scale which temperature heating surface (1) endanger safe operation of the boiler, shorten the life of the boiler water temperature is generally higher than the furnace 6 ~ about 10 ℃, but the presence of scale, leading to sharp increase in the temperature of the heating surface, will creep to overheating, increased corrosion of high temperature oxidation processes may cause metal deformation, bulge, or even rupture blasting; fouling layer of acidic or alkaline substances, it is easy to corrosion of metal equipment and shorten its life, seriously affecting the safe and stable operation of the boiler. (2) reducing the thermal efficiency, increased fuel consumption due to the thermal conductivity of only a few one-tenth scale steel, boiler heating surface scum resulting in reduced thermal efficiency, resulting in increased fuel usage. The data show that, when a surface junction raw 1mm scale, a 10% increase in fuel consumption; when the scale thickness of 3mm, about 25% increase in fuel consumption. Increased fuel consumption, will increase air pollution, which is the current energy conservation is contrary. (3) increased maintenance costs, environmental pollution if the boiler frequently produce large scale, in order to ensure its safe and stable operation of cost-effective, it would need to take timely and effective measures to deal with, or mechanical descaling, or chemical cleaning, a lot of manpower and resources will increase loss, produce a variety of charges. In particular, chemical cleaning, will produce a large basic or acidic wastewater, improper handling will cause serious environmental pollution.

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.
