Temperature is an important procedure to protect the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection device is a bimetal temperature controller
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.
1, when the safety door normally not automatically start, immediately forced open the security door, the door is opened to exhaust air, while reducing the thermal load of the boiler, reducing the steam pressure;
2, when the back seat is not safe door function, should be forced back seat, if the seat back mandatory security gate pulse invalid pulse should exhaust valve closing, so the seat back;
3, when all the safety door failure or serious over-pressure boiler, the boiler should be stopped immediately, can not continue to run down;
Electric research project on pressure meter for steam boiler features: 1, electric steam boiler automatic intelligent control technology, no need to be on duty. The operation mode is flexible and can be set to manual or automatic mode. 2. The electric steam boiler can set the automatic operation time period of the boiler according to the need, and several different working periods can be set up in one day, so that the boiler can automatically start each heating group in time-sharing. The heating group turns on and off circulation to make each contactor use time and frequency the same, and improve the service life of the equipment. 3, the electric steam boiler controller automatically controls, calculates and tracks the pressure, and it can be used to control the feed water pump when the load changes. Automatic start-up and stop control of electric heating tube, or manual control. 4, electric steam cooker The furnace has a full range of protection functions, leakage protection, water shortage protection, grounding protection, steam over-pressure protection, over-current protection, power protection, etc., boiler automatic protection, safe home. 5, Electric steam boiler body uses boiler pressure vessel steel plate, furnace body longitudinal welding seam is automatic welding, and carries on X-ray inspection, small boiler furnace body, mechatronics, easy to install and match; Large-scale boiler furnace body and electronic control separation design, to prevent the electrical control part affected by the furnace body high temperature, to ensure the stable operation of the electronic control device. 6, the steam boiler used in accordance with the JB/2379-93 and < metal tube-like electrical heating element technology. Conditions > requirements for low surface heating load electrothermal elements. High quality electric heating wire jacket thickened stainless steel pipe, filled with high purity magnesium dioxide powder, long service life of electric heating tube. Each group of electric heating components adopts flanged connection, which has the characteristics of simple structure, high mechanical strength, safety and reliability, convenient replacement and so on. 7. The electric steam boiler is compact in structure, scientific and reasonable in design and advanced manufacturing technology, which makes the boiler take up less space. Convenient transportation and saving site. 8, electric steam boiler is noise-free, pollution-free, high thermal efficiency, boiler body uses high-quality and high-efficiency insulation material as insulation, heat dissipation is small, energy saving and consumption reduction. 9, outside the electric steam boiler Packaging using famous color board package design, beautiful appearance, not easy to rust.
