After buying oil-fired boilers, many enterprises pay no attention to the maintenance and maintenance of oil-fired boilers, as a result, the service life of oil-fired boilers is greatly reduced. So how should the fuel-fired boiler be maintained? The following article for you to do a detailed analysis. When the furnace water is cooled below 70 ℃, the inner dirt will be completely removed, washed clean, all the manhole, hand hole, pipeline valve and so on sealed tightly, and completely isolated from the running boiler with blind plate. After all the alkaline solution is added, the boiler is injected with soft water until the water comes out of the top of the boiler. After closing the feed valve, pay attention to the problem. Mixing average of alkaline solution in boiler.
Selection pressure hot water dg type multistage boiler feed pump conditions What? For a larger number of floors, height or higher related businesses and institutions, the choice of hot water boiler, out of consideration of the actual situation, select the Metropolitan pressure hot water boiler, the selection pressure hot water boiler What are the conditions? Here Xiaobian take you to do a simple understanding. (1) The fuel pressure type hot water boiler, the thermal efficiency of the boiler, and so must be rated working pressure is under a relatively high steady state. Oxynitride (2) of the boiler, as well as other substances emissions compliance with national and local emission standards. (3) for heating relatively large range, relatively far from the heating, and the relatively high temperature requirements of the conditions, the need to use pressure hot water boiler. (4) pressure hot water boiler in the selection, to note problems with water treatment equipment, to ensure compliance with water, boost operational safety boilers. (5) provided in the high-rise building or a multilayer furnace room, the hot water boiler power is not more than a single 7MW, rated outlet water temperature not higher than 95 ℃. At the same time we shall obtain the approval and consent of the local safety watchdog fire department. Of course, the conditions for selection pressure hot water boiler is far more than that, regardless of which one aspect, we need careful handling and operation, if the timeliness of reach, it is very likely to cause a boiler accident, resulting in unnecessary the human and financial losses.
Recently, the Fujian Provincial People's Government formulated and issued the "Fujian Blue Sky win the Battle of three-year action plan to implement the program" (the "Program"), "plan" will fully implement the spirit of the party of nineteen, in strict accordance with the National Ecological environmental protection requirements, adhere to the development of new concepts, rule by the people, respect the source of prevention, treating the symptoms and so on, determined to win the battle of the blue sky.
"Program" Total thirty-nine, according to Xiao Bian finishing, a total of six boilers relevant content for your reference.
1, deepen industrial pollution control. As of the end of 2020, the completion of the sewage pipe catalogs specified in the license issued by the licensing industry issues, increase exceeded, waste-water treatment, fraud and other illegal activities. Promote key industries pollution control upgrades, the focus control area will strictly implement the Ministry of Environmental Protection issued the "Notice on the implementation of air pollutant emission limits in particular", the use of natural gas, Fuzhou, Quanzhou, in principle, two new projects to further promote the building construction ceramics ceramics pollution remediation; Zhangzhou City, the implementation of boiler "coal to gas" project.
2, optimizing energy structure. Until 2020, primary energy consumption control in 142 million to 1.62 million tons of coal, coal in primary energy consumption is reduced to 41.2%, increase the proportion of clean energy to 28.3%.
3, accelerate natural gas applications. Speed up the construction of natural gas infrastructure, improve the natural gas pricing mechanism, to further increase the use of natural gas.
4, an alternative propulsion power. Transportation, construction, industry, food, agriculture, tourism and other fields to accelerate alternative energy work. By 2020 the proportion of energy use accounts for about 29%.
5, deepen the comprehensive improvement of coal-fired boilers. Eliminated, shutting down 300,000 kilowatts of coal-fired boilers environmental performance is not up to energy security. And to carry out comprehensive improvement of the way and central heating coal-fired boiler. Cities above county level out of 10 tons of steam / sales and less coal-fired boilers, no new 35 steam tons / hour of coal-fired boilers.
6, strengthen the construction and management of the combustion zone ban. Each urban renovation to increase the range of high-pollution fuel combustion zone ban according to a division range, and punishes violation of the ban on burning zone management requirements.
7, improve energy efficiency. Dual control sustained energy consumption and working examples intensity. Strict management of energy-saving, energy-saving equipment industry and other key areas of work, to promote energy-efficient technology and low nitrogen products.
8, expand industrial furnaces governance. Localities to develop according to their industrial furnace implementation of comprehensive improvement program for non-compliance of industrial furnaces, small and medium sized furnace gas generator out of efforts to encourage the use of electricity, natural gas and other clean energy.
All cities in Fujian Province will strictly follow the "program" the development requirements of the implementation of the measures, so that the people responsible life, contribute to environmental protection goals.
