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.
Boiler Description coal to gas resource structure due to the characteristics of China's coal resource structure was in the proportion of relatively large, coal-fired boiler is also a time position in the market significantly. But with the changes in the structure of resources in recent years, and Huanjingwuran situation, relying on natural gas-fired boiler advantage is gradually replacing coal-fired boiler, a new main market. The "coal to gas" is also known more and more people! What is called the "coal to gas boilers": boiler from coal to gas specifically refers to the transformation of coal-fired boilers to gas boilers, boiler in the boiler is the transformation of the industry, so the boiler from coal to gas should still belong to the boiler industry. Because now the national requirements for environmental protection, many places ban coal-fired, the emergence of a lot of coal to gas boilers. (Only changes the combustion mode) is changed from coal to gas boilers, combustion section is not, in this small series is not recommended to transform combustion boiler. For the following reasons: 1, boiler belongs to special equipment, before coal-fired boiler into gas-fired boilers, in need of rehabilitation procedures, and next year's annual cumbersome. 2, an internal structure of coal-fired boilers with different gas boiler, heating surface, the radiating surface are different, the thermal efficiency of the boiler is very different, changing gas fired boilers, the original efficiency is only 70% -80%, the utilization efficiency is greatly reduced , although the initial investment cost is low, but in the long run is not worth the cost. 3, gas boilers are environmentally friendly automatic series, automatic water, low pressure from the high stop, excellent safety performance is much coal-fired boilers can reduce labor input and annual maintenance overhaul costs.
In recent years, vigorously promoting the "coal to gas" national project, in northern China have started to use gas dzl series coal fired chain grate hot water boiler to provide heating and hot water for residential, hotels, hospitals, shopping malls and some entertainment.
