Domestic small and medium-sized power plant fulton boiler generally adopts the medium pressure -3.82 MPa, 450 ° C or sub-high pressure 5.29 MPa-485 ° C, there is also low pressure parameters such as 2.5 MPa -400 ° C . If it is a condensate turbine for pure power generation, the higher the boiler parameters are, the smaller the boiler tonnage required for generating unit (1MW) electricity will be. If the lower the boiler parameters, the larger the tonnage of the boiler needed for generating unit (1MW) electricity. Medium pressure boiler can match 5 t/H for each MW for user reference, namely 5 mw pure power will need 25 t/H steam, say the pressure is 3.82 MPa and the temperature is 450 ° C.
Gas introduced a small hot water fulton boiler, means a small boiler, soft drinks dual small boilers (Rated evaporation does not exceed 0.5 t / h, rated steam pressure not more than 0.04 MPa boiler); 2, a small hot water boiler (Rated not more than 0.1 MPa water pressure water boiler, the pressurized hot water boiler); 3, small steam boiler (not tolerating more than 50 liters of water and steam boilers rated steam pressure of not more than 0.7 MPa); 4, aluminum small pressure boiler (bulk manufacturing aluminum material selection, rated outlet steam pressure not more than 0.04 MPa and not more than 0.2 rated evaporation t / h boiler).
To specifically address some of the difficult problems in steam fulton boiler: a basic aspect for the type of boiler, which is why we must all understand, therefore, is not missing any one of them. So, then, in response to this request, it may wish to continue to understand the steam boilers in order to increase the number of professional knowledge, and so they have a new harvest and inspiration. 1. water boilers, steam boilers that can be transformed into it? Water boiler, which is able to transform into a steam boiler, but it should be noted that, after the transformation of matter or the transformation of the former, should be no pressure boiler. Its specific operation, the drum is mounted at the top of the boiler with a pressure gauge, and then install the steam drum at the top of the safety valve, as the steam outlet. Thereafter, the water outlet of the boiler is connected on the drum, so that, the steam boiler can be obtained.
General Secretary Xi Jinping fully implement the important instructions on promoting clean northern winter heating, Xi Jinping adhere to the new era of socialist thought and nineteenth spirit of the party with Chinese characteristics as a guide, actively and steadily make 2018--2019 Nian northern clean heating season Heating work to ensure the safety of the masses warm winter, the energy Bureau of Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Shandong, Shaanxi, Gansu, Ningxia, Xinjiang, Qinghai, Henan province (autonomous regions and municipalities) and Xinjiang production construction Corps development and reform Commission (energy Board), Beijing Municipal Administration Commission, nuclear, China Guangdong nuclear power, China petroleum, China petrochemical, China national Offshore oil, national grid, Inner Mongolia electric power, China Huaneng, China Datang, China Huadian, the national energy State power investment Corporation, China Three Gorges, SDIC, China Resources coal, China electric power construction, China can build Group (company), power planning and Design, Water Resources and Hydropower planning and Design and other regions and major companies asked the following notification.
First, a solid grasp of clean heating embodiment implemented. At present, the country has been in accordance with the "Clean northern winter heating plan (2017-2021 years)" (hereinafter referred to as "Plan") requires the preparation of a clean heating embodiment of their respective regions, to develop a clean heating annual work plans.
Second, and steadily push forward the "coal to gas," "coal to electricity." Should adhere to the electric power, the gas should be air, should the coal is coal, the heat should be hot, for a given change, after the first stand break. "Coal to gas," gas will be to change, to implement gas supply further implementation of the transformation. All localities should earnestly fulfill the main responsibility to protect people's livelihood gas, good supply in the region decomposition of the implementation, coordination arrangements, rational use.
Third, actively expand the scale of renewable energy heating. All localities should combine resources, to improve geothermal resources exploration and development efforts under the premise of no damage to the ecological environment, simplifying formalities projects, improve the supporting policies, increased geothermal heating area.
Fourth, push forward clean coal-fired central heating. Coal should adhere to the coal, clean coal-fired central heating expanding area. By localities should give priority to production, as emergency reserves peaking power, improve the heating capacity of the unit, expand heating radius, planning and construction of people's livelihood back-pressure thermal power generating units, etc., to further encourage ultra-low emission cogeneration clean heating. Combined with coal production capacity to deploy a unified, rational part of the release of advanced coal production capacity, protect the livelihood of coal for heating. Greatly enhance the environmental performance of coal-fired boiler room, implementation of the "planning" on the ultra-low emission coal-fired boiler in City requirements.
Fifth, keep the masses warm winter safety bottom line. Around the implementation of clean energy supply in new heating facilities, safe and stable operation before, never allow removal of the original heating facilities. Better use of coal, electricity, natural gas and other energy sources for UNPROFOR, users still need to use coal for heating, a really good job of clean coal supply security work.
Sixth, to explore innovative clean heating mode. To clean around heating combined with practical, innovative institutional mechanisms to optimize the business environment, further liberalization of energy, heat production and supply areas, and guide social capital into clean heating market, encourage enterprises to carry out technological innovation and management innovation, the development of new technologies, new models The new format.
Seven, strengthen supervision clean heating work. According to "planning" urged all localities to innovative regulatory measures and means to closely follow the progress of work, mastery goal of task completion and work to promote the practical difficulties, in conjunction with the Energy Bureau sent regulators to organize the supervision and inspection and appraisal. All localities must submit the plan to the Energy Board by December 15 to submit the report within two weeks after the end of the heating season.
