Although some coal-fired power plants are reported to have been converted from coal fully mixed condensing boiler to natural gas boiler in power station, a 2010 study by the Aspen Environmental Group for the American Public Power Association reports that such "conversions," when examined, are replacements rather than retrofits:

Because of its advanced technology, noise-free, pollution-free, and wide range of applications, it is very popular in domestic and foreign markets. The fuel used in this kind of fully mixed condensing boiler is natural gas, biogas, petroleum and other fuels. It is transported by pipeline and does not need to store fuel when used. Therefore, it is more suitable in some environments such as food factories, schools, hotels and other places than boilers such as biomass boilers. . Steam boilers can be used not only for heating, power generation, but also for the industrial steam required for the production process. For example, food factories generally use steam boilers for the processing and disinfection of raw materials. As a result, the use of steam boilers is very common. And what kind of boiler to choose, you need to consider more factors.

Tongchuan City, Shaanxi Province is located in Fenwei plain, it is China's major coal producing area, the unique geographical location determines the Tongchuan coal energy as one of the main economic development. Tongchuan coal to bring rapid economic development, but a large proportion of heavy industry, atmospheric pollution and other issues are very serious. "Winning Blue Sky Battle three-year action plan" published this year, Fenwei plain was a key governance areas. Coal City is not achieved coal, coal is not coal, promote clean heating, Tongchuan City is a serious problem.

Tongchuan party secretary said: "This year Tongchuan 4905 ex situ poverty alleviation relocation of the masses of resettlement housing has been fully completed and turnkey, the actual stay 3763, is a large-scale relocation of mass arrival of new homes in the first year."

After a preliminary investigation, Tongchuan City to improve people's livelihood and environmental protection together, launched a "warm life, warm hearts and minds" of warm winter action. Based on the concept of local conditions, it has been completed in 40 of the city's centralized settlements, reduce operating costs, clear charges. Mastery of natural gas household heating settlements, natural gas boiler wall encouraging people to self-heating; central village of rural resettlement and scattered resettlement households, encourage and guide them to use electric heating and cleaning of heating equipment. All use of clean heating devices are available to the masses 1000 yuan subsidy.

Clean heating, an impact on the masses warm winter, a relationship with Blue Sky Battle Action Plan. It is understood that the city of Tongchuan coal-fired boiler to achieve a global "clear" in 2017. 2018, Tongchuan City by town gas central heating and household heating, rural households in accordance with the appropriate air dispersion of the gas, should the electric power, should be hot is hot, use clean coal coal should guide the masses to reduce the amount of bulk coal use, and the use of clean energy and the masses of poor people winter heating subsidies. Currently Tongchuan City, completed a total clean energy alternative to coal for 27,897, of which 25,196 coal to electricity, coal to gas 2701, the city's clean heating rate of 82%, the basic realization of the coal city does not burn coal, coal is not coal.

According to Eco-Environment Department data show that 11 cities Fenwei plain mean concentration of PM2.5 in October this year to 48 micrograms / cubic meter, down 7.7% year on year. The lowest average concentration of PM2.5 is Tongchuan city, is 38 micrograms / cubic meter.

Russia is located in the eastern part of Europe and the northern part of the Asian continent. The climate is cold. The average temperature in January is -18°C to -10°C. The average temperature in July is 11-27°C. Because of the cold climate, the Russian place places great emphasis on heating. Russia, on the other hand, has abundant energy resources and is the largest exporter of oil and natural gas. Therefore, Russia prefers the use of fuel gas fully mixed condensing boilers.
