Boiler For Central Heating

From the regular inspection and inspection of a large number of data reports, steam boiler for central heating users do not perform oxygen removal according to the requirements of GB1576-85, can not effectively control the water supply and boiler water indicators, the boiler operation mode is unreasonable, its own structural defects, Boiler maintenance can not keep up, etc., will lead to serious oxygen corrosion of the stressed parts of the heating surface of the boiler.

Recently, Anshun City, Guizhou Province, Anshun City, issued a notice to win the embodiment of the three-year action blue sky Battle, as follows.

First, the implementation of the total coal consumption control

Accelerate coal mergers and acquisitions, consolidation pace of technological transformation, and resolutely eliminate excess capacity to resolve the coal. Before the end of 2018 to complete the county level and above cities restrict coal-burning zone and the coal area delineation work to strengthen the loose coal burning and fireworks control, prohibit the sale, banned the use of coal, petroleum coke, high-polluting fuels. Vigorously implement the "coal to gas," "coal to electricity" project, increase the proportion of electricity, natural gas in energy consumption. By 2020, the city's coal accounts for the proportion of energy consumption is reduced to 70% or less.

Second, to carry out comprehensive improvement of coal-fired boilers

Before the end of 2018, the central city out of 20 tons of steam per hour of coal-fired boilers, 35 tons of steam per hour to start the following phase-out of coal-fired boilers. Atlantic Town Center City led Xixiu on the wind direction, seven Town, Cai town official reference implementation of February 15, 2015 promulgated the "Anshun City People's Government on delineation of high-pollution fuel combustion zone ban of" 3.5 Kunming Shanghai high speed range on both sides of one thousand meters anshun prohibit new paragraph 35 tons of steam coal-fired boilers. By 2020, the county (district) total phase-out urban area and 10 tons of steam coal-fired boilers, basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment. Center City ban on new built-up area per hour and 75 tons of steam coal-fired boilers, county (district) urban area 35 tons of steam per hour ban on new coal-fired boilers and other regions 10 tons of steam per hour ban on new coal-fired boilers . Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage.

Third, improve energy efficiency

Continue to implement the action of the total energy consumption dual control and strength. By 2020, the city's yuan GDP energy consumption fell 14% in the region, the total energy consumption control in less than 28.55 million tons of standard coal, new energy consumption control in less than 100 million tons of coal. Strengthen the implementation of energy efficiency standards to promote, develop, promote energy-saving technologies and products to achieve key energy industries, energy-saving equipment standard full coverage.

Fourth, accelerate the development of clean energy and new energy

As of 2020, the installed capacity of wind power reached 200,000 kilowatts; actively seek Zhenning County, Guanling County, Ziyun County PV poverty alleviation projects Indicators Program, to encourage qualified enterprises to implement photovoltaic bidding, led a group of farmers light, light forest project floor building.

The thermal conductivity of the scale of gas-fired boiler for central heating is only one-tenth of that of steel when it is running. After scaling on its heated surface, the heat transfer effect will be hindered. In order to maintain a certain output of the boiler in the course of use, the thermal conductivity of gas-fired boiler is only one-tenth of that of steel when it is in operation. It is necessary to raise the temperature on the side of the fire.
