About vertical steam boiler: a comprehensive domestic vertical steam boiler furnace various types of technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product design has been declared national patent, the boiler body potshell head, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney.
Poor water quality caused by damage to the boiler: poor water quality, means the water contains a lot of impurities. Boiler feed water may contain impurities in the raw water are: suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and the dissolved gas. If this water without any treatment, once inside the boiler, will bring the following hazards:
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.
