water pretreatment for high pressure boiler
Right after the shutdown shutdown and maintenance methods steam water pretreatment for high pressure boiler: I believe it is not strange for large steam boiler, we know when its not in use in order to reduce waste of resources, it needs to be shutdown. But it's the right way to shutdown and how much you know about it? After the shutdown maintenance methods and how is it? Here's a small series and learn together about it!
Power station water pretreatment for high pressure boilers are generally dominated by coal. In the long run, with the promotion of environmental protection technologies, lower power generation costs, and increased power demand, the coal-fired boilers for power stations have great potential for development, including CFB (circulating fluidized bed boilers). ) Boiler growth potential is significant.
Water tube water pretreatment for high pressure boiler design
Water-tube boiler design
Henan Provincial Government to respond positively to meeting the spirit of the "Blue Sky Battle Action Plan", in mid-September, the issuance of "three-year action plan for pollution prevention and control campaign of Henan Province (2018-2020 years)" ( "Program"), under provincial jurisdiction, provincial tube county (city) people's government and provincial government departments need to be strictly enforced.
A gradual reduction of the total coal consumption
1, and strictly control the total coal consumption. Strictly implement the "People's Government of Henan Province, Henan Province, on the issuance of" Thirteen Five "total coal consumption control notification program of work." Strengthen the electricity, coal, steel, chemicals, nonferrous metals, building materials and other key industries of coal consumption reduction measures to eliminate a number of energy consumption is higher than the national average of inefficient capacity.
2, to enhance coal project access threshold. In principle ban on new or expanded production capacity of pure coal, coal, iron and steel, electrolytic aluminum, cement, glass, traditional coal chemical, coke overcapacity of traditional industries, the province's non-new chemical park.
3, an alternative embodiment of the coal reduction. Strictly implement the "coal project in Henan coal consumption of alternative management (Interim) Measures", all new construction, renovation, expansion project be implemented coal coal reduction or equivalent alternative. For failure to complete the annual coal consumption reduction objectives of local, regional limits approved implementation of coal projects. In addition to cogeneration projects, the province no longer approve new production of "Thirteen Five" period coal-fired power projects.
Second, build the province's clean heating system
1, the basic realization of full coverage of urban central heating. Based on existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots.
2, vigorously promote clean energy for heating. Central heating pipe network coverage area, the power supply and secure place, the implementation of clean energy heating engineering, accelerate the promotion of ground source, water and air source heat pump technology, building a number of distributed energy heating project; in the natural gas pipeline network to cover the area, on the premise of the implementation of gas supply contracts, ordered the construction of gas-fired boiler room, natural gas distributed energy projects.
3, strengthen clean coal quality control. Continued to organize provincial, city, county, township (neighborhood) and village (community) scattered five coal-burning governance special inspection operations, according to the law to crack down on sales of substandard clean coal behavior.
Third, the development of industrial coal-fired facilities Chaigai
By the year 2020, and out of the basic ban coal stove cogeneration heating pipe network coverage range fired heating, drying furnace (kiln); out hearth furnace diameter of 3 meters fuels gas generator, increase fertilizer industry fixed bed coal gasifier intermittent reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke.
Fourth, to promote the comprehensive improvement of coal-fired boilers
Demolition and gradually expand the boiler clean energy transformation of coal-fired range. Before the end of 2020, the province basically eliminated 35 tons of steam / h and coal-fired boilers.
Boiler Chaigai funding awards complement the implementation of the way decreasing year by year:
The completion of the coal-fired boilers Chaigai before the end of October 2018, giving 60,000 yuan / tons of steam financial awards complement;
The completion of the coal-fired boilers Chaigai before the end of October 2019, giving 40,000 yuan / tons of steam financial awards complement;
The completion of the coal-fired boiler Chaigai after the end of October 2019, no longer give financial awards complement.
