For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.
1, to carry out special treatment industrial furnaces
Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.
2, to carry out clean alternative
Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.
3, to carry out comprehensive improvement of industrial boilers
Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.
4, strengthen upgrading gas-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.
5, strengthen upgrading oil-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.
6, vigorously promote urban central heating
Full use of 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. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .
Henan fast 8 ton diesel boilers pressure 10bar manufacturers of gas boilers, gas boilers including WNS series, SZS gas boiler, etc., with the realization of the country "West-East" project, the more energy saving high performance gas boiler gradually become the first choice of people's minds device.
Condensing 8 ton diesel boilers pressure 10bars can be used in enterprises, hotels, military, railway stations, airports, factories, hospitals, schools and other occasions. Its main use features are: high thermal efficiency - more money; exhaust gas temperature is low - more environmentally friendly; output medium temperature - good steam / hot water quality; high safety factor - once an exception occurs immediately start the alarm system.
Industrial 8 ton diesel boilers pressure 10bars and gas condensate natural gas hazard industrial boilers produce condensate water hazards 1, the corrosion of condensate water boiler heating surface of the main hazards to the natural gas industry is a corrosive effect on the boiler heating surface of the boiler. Condensate corrosion WNS rear of the boiler heating surface of the bottom of the tube focus, mainly iron oxide corrosion products. Condensate corrosion can cause intense side wall thinning, strength weakened. (1) condensation with the flue gas evolution corrosion, some CO2 is dissolved in the condensed water, CO2 generated in case of weak electrolyte H2O H2CO3, ionized hydrogen ions, so that a weak acid condensate, and another part of the nitrogen oxides and containing a very small amount of sulfur dioxide dissolved in the condensate, enhances the acidity of the condensate, the pH of the condensed water as in table 1 were lower than the position of the drum 4.3. iron hydrogen evolution corrosion can occur in the acidic solution, and the strong acid, the reaction The faster rate. (2) Since the oxygen etching gas during combustion boiler need to ensure a certain air ratio, combustion flue gas contains oxygen. When the steam condenses, some oxygen will be dissolved in the condensed water, causing corrosion of the metal heating surface of the oxygen. 2, when the cross-sectional area to reduce the flue gas flow type gas boiler industrial boilers operate at low load, the heated surface of the flue gas, the condensed water gathered in the smoke tube, the resulting corrosion products accumulate in the bottom of the tube, even clogging of the pipe part, thus reducing the flow area of the flue gas, the flue gas resistance increases, and increase in power consumption of the blower. 3, the furnace temperature is lowered, damage to the burner within the examination of natural gas in industrial boilers, often find a certain amount of condensed water. We found condensate discharge tube boiler such severe congestion, resulting in condensed water in the lower furnace does not discharge, and refluxed for aggregation. When the boiler is started, the heat accumulated in the furnace absorbs the condensed water and evaporated fuel combustion, thereby reducing the furnace temperature. If the furnace condensate accumulated too much, and even dipped into the burner, causing damage to the burner. Suddenly turn off the boiler, the boiler does not start, because the burner too much condensation water immersion, affecting the safe operation of the boiler. 4. Effect of boiler condensate generated on the heat sealing material penetrates into the sealing material of the boiler insulation, the point of the arrow indicated gas tank gas boiler WNS industrial boilers. Sealing condensed water immersion insulation material for a long time, the insulation effect will be weakened or even physical damage, increased heat loss. Meanwhile, the condensed water will make the sealing material deformation aging, sealing capability weakened, leading to a certain amount of flue gas emissions, which not only be dangerous, can also cause a certain amount of heat loss.Free Chat
