what causes high pressure on steam boiler

The construction of gas boiler rooms generally follows three principles: site, space, and protection.

To put it simply, the location of the boiler room should not interfere with production and life, and it should be suitable for the distance from the main building. On the one hand, the best safety distance is to minimize noise interference.

Reconstruction of the boiler, "coal-fired furnace gas furnace change" concrete has been improved from what? With the boiler industry, continuous improvement and innovation, many companies would rather make the appropriate boiler according to production needs, of course, there are many in practice transformation plan, each different rehabilitation programs boiler will also have their different benefits, today we are introducing is the coal-fired boilers into gas boiler, then the transformation of such a high-quality boiler from which specific aspects begin to improve it

Buy hot water boiler needs to pay attention to what: hot water boiler is mainly used for domestic hot water or heating, commercial cooking and food processing. In the selection and purchase of hot water boilers, note three main technical parameters of boiler power. With these data, we can clearly understand the standards and the ability to supply hot water boiler products. Hot water boiler power relationship between the input power and the cost of hot water boiler heat boiler means provided in unit time. It can be expressed in calories or kilowatt kilowatts or megawatts MW.

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.
