Are gas-fired 10 ton mobile steam boiler manufacturerss environmentally friendly? Gas-fired steam boiler, which can be regarded as a gas-fired boiler, can also be regarded as a steam boiler. This boiler, from a professional point of view, is an environmentally friendly boiler, compared to oil and coal-fired boilers, because it uses gas. Moreover, the thermal efficiency of this kind of boiler is very high, can reach more than 90%.

Zhejiang Yiwu issued the "Yiwu winning Blue Sky Battle 2019--2020 action plan." Plan to improve air quality, enhance people's happiness index target put forward concrete measures of implementation, as follows.

1, vigorously develop clean energy. In-depth implementation of the "creation of a national clean energy demonstration Zhejiang Province Action Plan (2018-2020 years)" "Zhejiang three-year action plan for natural gas development (2018-2020 years)" and "Jinhua" Thirteen Five "Renewable Energy Development planning". According to "gas of the gas should be '' should the electric power" principle, energy companies actively guide clean energy alternative embodiment, in 2020, the proportion of the power in the final energy consumption of clean energy consumption accounting for the higher level, the city gas consumption amounted to 150 million cubic meters.

2, control total coal consumption. Strengthen energy consumption and total energy consumption intensity dual control, strict new coal project access, new (modified, expanded) construction project coal consumption reduction of coal instead. By 2020, the city's total coal consumption by 2015, down from more than 5%. Continue to promote alternative energy coal and oil, replace reached the national requirements. No new 35 t steam / hour or less polluting fuels boilers. Strengthening coal quality control, promote clean coal utilization. Before the end of 2020, clean coal utilization rate of 92%, the proportion of electricity than to accept deliveries in 2017 significantly increased.

3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers, the urban built-up area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically out of 10 steam tons / hour and 35 steam tons / hour coal-fired boilers. 35 t steam / hour and more polluting fuels boilers completed ultra-low emissions and energy transformation. Low nitrogen gas boiler basically completed the transformation. Strict control of the new urban area of ​​biomass boilers. Biomass boilers should be dedicated boiler, blended prohibit other fuels such as coal, and other supporting efficient dust bag embodiment, non-coal, oil, natural gas-fired boilers and the like directly Burning biomass briquettes.

4, the positive development of central heating. Cogeneration units to increase the technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release before the end of 2020, phasing out the cogeneration district heating pipe network coverage and high pollution coal-fired boilers in the range. In the area where no cogeneration district heating conditions, a plurality of existing small coal-fired boilers, an alternative construction of large-capacity coal-fired boiler in accordance with the principles of the reduction or the equivalent.

5, deepening the construction of high-pollution fuel combustion zone ban. According to "adjust Yiwu prohibit the use of polluting fuels sales area plan" (Yi Zheng Ban Fa [2018] No. 180) documentation requirements, a comprehensive investigation and eliminate high-polluting fuel facilities within the city, to ensure that no dead ends, no blind spots, Finish high pollution fuel combustion zone ban burning building before July 2019.

6, improve energy efficiency. Vigorously develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New energy-intensive projects per unit of product (output) energy consumption should reach the international advanced level. Local conditions to improve building energy efficiency standards, and increase efforts to promote green building, city guide implementation of green building standards for new buildings. Renovation of existing residential buildings to promote energy conservation, encourage rural energy-saving housing.

Gas boiler installation and preparation requirements of (a) the preparatory work before the installation of a boiler installation must be installed by the unit has installed a license .. The installer must be familiar with "Boiler Safety Technology Supervision", and carefully read the installation instructions and other random technical documents. 2, a mounting position: 1) as close as possible to install a boiler steam, hot site, to facilitate shortening the hot water and steam pipes, reducing capital costs, reducing the pipeline heat loss. The installation site should be water supply, sewage convenience. Burning light diesel oil, heavy oil residue and the boiler must be closer to the oil reservoir; burning natural gas, town gas boiler must be easy to close the gas source. 2) boiler room layout should follow the "Boiler Safety Technology Supervision" relevant provisions "boiler room", to be well-lit, well-ventilated, no ground water, ease of operation and maintenance, boiler room must be equipped with at least two fire extinguishers 1211. 3) Check the boiler foundation, prepare the boiler in place. 3, equipment acceptance: acceptance by conduct an inventory purchase contract or supply list. 4, lifting large boiler: not less than 1.1 times the lifting equipment of large weight of the boiler, two lugs for the lifting jack top or at the bottom edge away slowly, not to any other parts of the lifting or addendum to avoid damage to the boiler. (Ii) installation requirements: 1, the main steam line installation requires the main steam lead pipe height is generally greater than 0.5 m, the bending radius should be greater than or equal to 5 times the diameter of the pipe, the pipe should be installed at the lowest trap, preventing water pipe, It should be a main steam pipe insulation. 2, a main return pipe installation requirements should the main return pipe elbow minimize installation, to facilitate the mounting operation of the valve, piping should be insulated. 3, the hydrostatic testing relief valve, the safety valve should be installed in the exhaust pipe, the exhaust pipe connected to the straight pipe outdoor safety. 4, should be connected to a sewage outfall tank or other security, the pipe should be secured to prevent shifting or counter scald accidents blowdown. 5, railings, stairs (with large oven) after the positioning by drawing the boiler installation. 6, water table must be installed to the lighting device, easy to install or inspection.

Electric utility interest in supercritical pressure steam cycles has revived in the United States after waning in the 1980s. Since supercritical cycles yield higher plant efficiencies than subcritical plants along with a proportional reduction in traditional stack gas pollutants and CO{sub 2} release rates, the interest is to pursue even more advanced steam conditions. The advantages of supercritical (SC) and ultra supercritical (USC) pressure steam conditions have been demonstrated in the high gas temperature, high heat flux environment of large pulverized coal-fired (PC)boilers.
