water boiler 1570 KW
January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.
Prior to 2017, the total removal of Harbin urban built-up area of small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.
According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.
2. Steam boiler in hospitals
Healthcare facilities are generally intensive energy users compared with many other buildings, because of their specialized requirements for 24-hour working. Steam is used widely in many hospitals to provide hot water, space heating and sterilization services. There are good reasons for this. Steam is an efficient and controllable heating medium that is proven to be reliable, safe, flexible and sterile.
How to determine when the steam boiler plant accident occurred less water when the water level has been less than the minimum level is defined, but the water can still be seen in the gauge water level, slightly less water is determined; when the water level can not see the water meter, it is determined severe water shortages. Status summarized in the following: a conventional water level (1) is less than the height of drum level defined; (2) low level alarm, automatic warning sounds, warning light flash from; (3) superheating steam temperature increases; (4) Enter water is not a conventional, inferior steam flow rate value; (5) the flue gas discharge temperature.
Paper mill steam boiler water treatment method which is currently, steam boiler is commonly used as a paper mill boilers, used for disinfection, medicine and other suffering. For the pharmaceutical industry this particular area is concerned, the requirements for steam and hot water level is relatively high. This step treatment that becomes more important, the following small series bring you a quick look at the water treatment methods, results and so on. Simply put, the purpose of boiler water treatment is provided by the addition of certain equipment, such as impurity removal of boiler water softening treatment, prevention of boiler corrosion or fouling occurs, in order to ensure good quality of steam, but also conducive to the boiler thermal efficiency, in terms of the paper mill, which is more in need. Paper mill steam boiler water treatment method: (1) In general, when the boiler water treatment boiler to take into account their own situation, and using regional boiler. Vapor pressure for evaporation and a small part of the boiler to be equipped with oxygen equipment in accordance with the actual situation, while the outer pot for the chemical treatment. (2) If the local water contains more impurities, water should be filtered before or during precipitation, so as to avoid blockage of the boiler water treatment equipment, water treatment effect is low, the efficiency is not high. (3) In addition, we should note that, during the boiler water treatment equipment selection, cut not covet low price, ease of use and other considerations while ignoring the quality of the equipment, so not only can not be effective treatment, but can also result in energy waste and reduce the life of the boiler. You know, for a long time corrosion and fouling it is easy to make low thermal efficiency of boilers, boiler unnecessarily severe accident. In short, this kind of steam for the paper mill quality and environmental protection fields of high, must be strictly water treatment steps, in accordance with a qualified water treatment methods and standards.
