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.
Check the ignition before the gas asme boiler water treatment guidelines and gas boiler should pay attention to the project pre-purge before ignition, the pre-purge can clear the air in the furnace chamber to prevent knocking, before each ignition must be strictly enforced. 1, 2 Open the power to start the gas burner 3, when the discharge valve on the drum, the steam comes out completely when it is closed 4, the boiler inspection manholes, hand hole flange and valves, the leak was found to be fastening, such as fastening the leakage maintenance shutdown 5, when the steam boiler pressure liter 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table 6, when the steam pressure was raised to the boiler when 0.1 ~ 0.15MPA, rinsed gauge trap 7, when the steam boiler pressure was raised 0.3MPA, the fire load / small fire fire knob to enhance combustion. 8, when the air pressure steam boiler operating pressure was raised 2/3 when started warm air supply tube, slowly open the main steam valve, to avoid water hammer 9, when the drain valve is completely out of steam 10 to turn it off, after all drain valve closed, slowly open the main valve to open, and then turning half-rings 11, the gas burner control knob to the automatic transmission.
ZG asme boiler water treatment guidelines deeply understands the connotation of the "Internet +" era, closely follows the national strategy of the Belt and Road, and opens the brilliant curtain of ZG boiler cross-border e-commerce. At present, ZG boiler 's sales network covers more than 80 countries and regions around the world, and ZG boiler 's products are continuously sold overseas.
Features WNS type gas pressure hot water asme boiler water treatment guidelines WNS What are the characteristics of the type of gas pressure hot water boiler which features WNS type gas pressure hot water boilers have what? Boiler by the boiler tubes, and double-wave oven can return flue composition mixed with the air to ignite the fuel rod electronic ignition burner, injection waveform burner, high temperature flue gas to the combustion chamber of the furnace two convection bank state, the sub-packets into flue economizer (optional), a boiler feed water preheater, while further reducing the temperature of the boiler exhaust gas, and finally discharged to the atmosphere through the chimney flue. WNS type gas pressure hot water boiler Features (1) the use of CAD computer graphics software to optimize the design to ensure good water circulation, small flow resistance. Heating surface heat transfer coefficient is fully optimized, high thermal efficiency. (2) Special Equipment Association of Henan Province drawing safe and reliable. (3) downstream of the body is a horizontal wet return all three structures, a large heat transfer area, the thermal efficiency is much higher than the normal center structures, (4) primary compression element is butt-welded to ensure the welding quality. (5) interpolation spoiler smoke tubes, high thermal efficiency; (6) furnace bile formation, the use of special materials to protect the furnace. It can also ensure that the water is clean and clean. (7) furnace open manhole, hand hole to facilitate maintenance; (8) burner equipped with imported Italian Baird burner valve group including filtration devices and leak detection devices. Combustion and good regulation performance, safety and efficiency; (9) with a dry boiler combustion apparatus, in order to prevent damage to the boiler water.
Nov 10, 2014 · Influent water used for drinking, boiler make-up, cooling and process applications is derived from one of three sources: underground (wells), surface (ground), or reuse (water treatment plants).
