different types high pressure boiler

A few days ago, Datong City, Shanxi Province, issued a "decisive battle 300 days, to enhance the" Datong blue "plan", combined with ongoing Shanxi Province: innovation, work for "the great debate, promote green development, and constantly improve the level of ecological civilization, achieve a good number of days 300 days throughout the year for more than two goals. details are as follows.

1, aspects of the transition. On the basis of the regulation last year, continued to carry out "dirty scattered" enterprise rectification work. According to industrial policy, industrial layout planning, as well as land, environmental protection, quality, safety, energy consumption, etc., to carry out an intensive investigation, the establishment of management accounting. In accordance with the principle of "first stop after the rule", the implementation of classification disposal, have been banned "dirty messy" business, appears to prevent the resurgence of the phenomenon.

2, corporate governance aspects. Industrial pollution discharge standards to strengthen the comprehensive management of enterprises can not achieve full compliance, should be taken to stop production remediation. Full completion of key industries pollution remediation work, on the basis of the city's nine power companies that run on ultra-low emissions stable, GD Datong Power Generation Co. Ltd. within the scope of the built-up area of ​​the city and Datang International Yungang Thermal Power Co., Ltd. completed before the end of the colored Amidst the governance feasibility report, we lay the foundation for next year colored misty rain governance. December 30, 2019, to carry out ultra-low emissions and chemical industry, iron and steel, nonferrous metals, cement industry, especially emission limits transformation; completed 100 industrial enterprises fugitive emissions control, industrial furnace control 41 upgrades, 11 key industries and enterprises volatile organic compounds governance and four key industries and enterprises volatile organics management upgrade.

3, less coal ways. Insist on proceeding from reality, should be in accordance with the electric power, gas should the gas, should the coal coal (ultra low emission), should be hot is hot, and more heating energy policy to ensure the safety of the masses warm winter. Residents living coal simultaneous implementation of clean energy alternatives. District heating flat built-up area clean 100% coverage, coverage of other counties clean heating built-up area of ​​more than 70%, 40% or more in rural areas, to proceed with the phase-out of coal-fired boilers. Renovation project to carry out ultra-low emission coal-fired boilers, October 1, 2019, 65 tons of steam coal and above and build the region (biomass) and energy-efficient boilers to complete the transformation of ultra-low emissions, low nitrogen gas boiler basically completed the transformation.

At this time the sewage regularly, the water discharged from the bottom part of the circulation circuit, to discharge impurities, to ensure the quality of different types high pressure boiler water; weak and the heated circulation loop heat exchanger portion strengthened to prevent local stagnation of the water cycle, so that each of the water circulation system heating surface uniformly expanded metal member, reducing the temperature difference between upper and lower walls drum.

Henan Notes different types high pressure boiler gas leak problem Henan precautions gas boiler leaking problem: ① the inner wall of the Henan gas boiler leaks: leak is also divided into the inner wall of the drum and the provision of water leakage and water cooling pipe leakage drop, if the former is relatively small leakage eye, can be Wabu same steel, after Patching flaw detection. Leak needs to be replaced before the tube, replacing a large area. ② Henan leaking gas boiler handhole: re-try transducer mounted at an angle, to see if there is a hand hole cover deformation, if deformed, the first correction, and then the green tape wrapped in a layer of a uniform mat, and preferably consistent position before overhaul . ③ gas leak in the boiler drum: the higher cost of repair costs, mainly to see the location and size of the leak leak point where, if the old boiler appears oozing red pot of water, indicating that water quality problems, probably because of low alkalinity or water metal corrosion caused by dissolved oxygen is too high. Low alkalinity can adding sodium hydroxide or trisodium phosphate to a pot of water, dissolved oxygen in water is too high to be resolved by the deaerator. ④ leaking water treatment system: first check whether the gas boiler corrosion, if you need to descaling the boiler corrosion, leaks repaired part, and then circulating water treatment, adding agents, equipment and other materials were boiler corrosion, scale, protection . ⑤ boiler flue gas leak: check is not the boiler tube or tube sheet due to cracks, if the need to change the pipe, see Wabu flue used material, aluminum, and stainless steel may be carbon steel or argon welding aluminum wire, iron acid electrode material directly. ⑥ leaking valves: Valves leaking packing should be added to or replacement of the valve.

2. High penetration of automatic control systems makes operation and running simple.

3. It has good steam boiler service which ensures reliable and timely maintenance to avoid boiler failure.
