Mainly refers to a substance dissolved salts dissolved in water and certain gases. We usually use mostly natural water, but its natural water itself containing various dissolved salts, calcium and magnesium salts wherein the high hardness material, is the main source of causing boiler fouling. High hardness, calcium and magnesium salts substance easily condensed into the scale, the scale mentioned earlier is one of the main factors affecting boiler corrosion. So, first of all we want is how to effectively prevent condensation of high hardness, calcium and magnesium salts substance, here we have to pass some chemical drugs to achieve such a treatment effect.
10, electrically heated tube furnace in the vapor easy to scale. If there is no softening equipment steam boiler, electric heating is recommended once a month detached, to remove the scale. If treatment equipment should disassemble the tube was heated at six months or a descaling. Re-power heating tube should pay attention to the connection of the recovery, the screw fastening flanges good, should be symmetrical fastening screws tightened repeatedly tightened to avoid water leakage occurs.
11, when the boiler is stopped, the power should be cut off, the control box is opened, check all the electrical connections of the nut member, looseness should be tightened to prevent poor contact and electrical wires burning member.
Recently, the field of ecological environment of Shanxi thorough investigation of illegal activities, promotion of eco-environmental quality of Shanxi be greatly improved, the central group held a provincial environmental inspectors rectification illegal sewage major renovation "Hundred Days cleared" special action mobilization meeting, asked the province up and down quickly action to ensure that the "Hundred Days cleared" special action to achieve tangible results.
"Clear Days" special action include 10 aspects: the central environmental protection inspectors and inspectors "looking back" clear feedback issues; national air pollution control and strengthen supervision and three cities in northern Shanxi air pollution control special inspection found problems rectification task clear; focus on the problem of sewage from polluting units cleared; "ban on coal zone" bulk coal cleared; "scattered dirt" enterprise is cleared; key areas of coal-fired boilers cleared out of the task; urban area construction site dust pollution problem is cleared ; diesel truck phenomenon of black smoke cleared; cities above the county level and type of surface water environmental violations centralized drinking water source protection areas cleared; annual key water pollution control project is completed cleared.
Clear focus: focus on examination of 624 key polluting units of pollution control facilities, operation and pollutant emissions. Implementation of the rectification May inform the Provincial Department of environment and supervise the handling of seriously overweight key sewage units - one by one to verify the fourth quarter of 2018, in 2019 the Department of Ecology and Environment informed the first quarter supervise the handling of seriously overweight key polluting units, 2019 1 situation and the implementation of administrative penalties.
Specific objectives: 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, slashing the average concentration of sulfur dioxide in the ambient air quality.
Clear focus: the use of coal for municipalities within the scope of "no coal zone" in the home spot checks to ensure that alternative livelihood and heating coal for clean energy or clean heating methods is strictly prohibited within the store "ban on coal zone" sales and burning the behavior of coal and its products.
Clear Focus: targeted surveillance cities out of the task list of coal-fired boilers. In built-up areas to ensure that municipalities and districts out of 35 tons and coal-fired boilers, county (city) eliminated the basis of built-up area and 10 tons of coal-fired boilers on October 1, 2019, Taiyuan, Yangquan, Linfen City, Jinzhong city, four global, Luliang Fenyang, Xiaoyi, the text of water, Jiaocheng, Yuncheng salt lake, Wenxi, Xinjiang, Jishan, Hejin global phase-out of 35 tons of steam coal-fired boilers, Changzhi city completed 35 tons of steam out of the task more than 50% of the amount of coal-fired boilers, Jincheng complete 20 tons of steam coal-fired boilers eliminated within the municipal area.
Effective method of medical boiler drum level measurement of effective methods of medical boiler drum level measurement Currently, the pharmaceutical industry is commonly used in boiler sarch new model steam boiler, steam boiler will inevitably experience some operating drum level measurement, then the medicine steam boiler What an effective way to measure the water level package has it? drum level measurement can be run on the stability of steam boilers, power and work carried out clearly positioned to ensure its operation in a safe state. Basically, the method of effective medical boiler drum water level measurement can be divided into two, one link type, and second differential pressure. The former can be divided into two-color water level gauge and a measuring electrode type; color water level gauge for determining chromatic aberration by the optical principle; measurement electrode type level gauge is determined according to the difference of the electrical conductivity of soda. The latter name suggests is to a simple determination of the water level changes according to the pressure conditions. In short, whether it is China Unicom type or differential pressure measurements are way more effective, but also more common method of measuring drum level, we can choose according to the actual situation, to effectively monitor the state of the water level in the steam drum to ensure the smooth operation of the boiler and security.
