Industrial boiler water quality standard industrial boiler water quality standard industrial boiler water quality standards for a range of industrial boiler water quality standards of this new standard specifies the quality requirements during operation in industrial boilers. This standard applies to the outlet steam pressure less than the rated 2.5MPa. Water as a medium and fixed in steam boiler steam boiler water as a medium is also applicable to a given water as a medium pressure hot combined 0 5 ton water boilers supplier and pressure hot water boiler. Second, the industrial boiler feed water quality standards 1. Steam boilers and steam boilers are generally required to use chemical water treatment outside of the pot, and the water quality must meet the requirements in Table 1. Tends to 1) hardness Lc basic unit (1 / 2ca2 + 1/2 Mg (2+), the same below .2) alkalinity MMO1 / L basic unit is C (OH-, 1 / 2CO2-3, HC03 -). On the alkalinity index value is not high boiler after reporting to the local boiler and pressure vessel safety supervision mechanism no overheating, which can be appropriate to relax the limits on the alkalinity index. 3) When the amount of evaporation than or equal to the nominal 6t / h boiler should be oxygen, localized corrosion was found, measures to be taken deaerator feed water, the oxygen content of the boiler feed water or steam turbine should be less than when less than 6t / h boiler rated capacity equal to 0.05 mg / L. 4) If the dissolved solids is difficult to determine, by measuring the conductivity or chloride ions (C1 -) indirect control, but the relationship between conductivity and dissolved solids or dissolved solids and chloride ions (of Cl-) ratio should be determined EXP . food. This ratio relationship should periodically re-tested and corrected. 5) only fuel, gas boiler 2, equal to or less than the rated capacity 2t / h, and less than or equal to 1.0MPa rated steam pressure, steam boilers and soft drinks dual boilers (steam, no special requirements such as quality) and the metering process can be application. But we must strengthen the boiler scaling, corrosion, monitoring water quality, good feeding, sewage and cleaning. Boiler water quality should meet the requirements of Table 2.
How to diagnose the gas boiler to produce steam when water shortages already inferior to the minimum water level height limit, but when the water meter in height can still see the water, mild sentence less water; when the water level was observed visually count is less than the height of the water when sentenced to severe water shortages. Status as summarized below: (1) conventional water drum divided highly water-inferior height defined; (2) low water levels prompt alarm will sound, lights light initiated; (3) the temperature of superheated steam to improve the water vapor; (4) conventional water not provided, steam flow is lower than the value; (5) steam temperature increase smoke emissions.
Use vertical hot combined 0 5 ton water boilers supplier needs to understand what issues suggest that you be sure to choose a professional operator to care, although the moment vertical hot water boiler can already be fully automated intelligent operation, but the operator on duty is important, just like this quickly discovered when unexpected circumstances, we can put an end to cause more severe loss to prevent unexpected cause. Steam boiler must know which local gas boilers | oil-fired boilers | steam boiler Environmental Equipment Co., suggested that everyone must have the experience to pick staff to guard, even though the moment may have reached a steam boiler automatic intelligent operation, but the staff still on duty It is necessary, so that timely notice in the event of unexpected problems can lead to greater reduction of wear and tear, to guard against any eventuality produce.
Recently, the Xinjiang region issued on the overall strengthening of environmental protection and resolutely fight pollution prevention tackling embodiment, the program provides: Complete with ultra-low emissions and energy-saving transformation of the conditions before the end of 2020, coal-fired power plants. Gradually shutting down key areas do not have the conditions for the transformation of highly polluting coal-fired power plants.
Implementation of the program focus on the regional party committee, "1 + 3 + 3 + reform and opening up" work arrangements, accelerate the construction of ecological civilization system to ensure that by 2020 the basic layout of the formation of the main functional areas, land space development pattern was further optimized, the total emissions of major pollutants and the amount of energy consumption per unit of GDP dropped significantly, significantly reduced the number of heavy pollution days. Specific indicators: the region of fine particulate matter (of PM2.5) concentrations of the standard level cities not decrease by 15% in 2015, the level of urban air quality days ratio reaches 71.6%; good monitoring of river water quality of the region (or superior to class III) ratio of not less than 97.6% (national quality evaluation section 47 excellent no less than 91.5%, worse than Grade V ratio of not more than 4.28%), focus on monitoring water quality of lakes and reservoirs of not less than 71%; sulfur dioxide , nitrogen oxides, chemical oxygen demand, reduce ammonia emissions into the 2015 3%, 3%, 1.6%, 2.8%; contaminated land safety utilization rate of 98%, contamination of land utilization is not safe less than 90%; the red line accounted for ecological protection area of not less than 25%; forest coverage rate reached 5.6%.
Program has clearly pointed out, we must strictly control the total coal consumption, accelerate the use of clean energy alternatives. Study the development of the region's total coal consumption embodiments and independence - - "Kui" Ukraine - - Chang stone "of the total area of coal consumption Ukraine" reduction plan, the implementation of the target responsibility management, controlling the total coal consumption. Delineation work carried out high-pollution fuel combustion zone ban, ban the sale in the region ban on burning, burning high-polluting fuels. Increasing the use of clean energy, clean energy consumptive broaden the channels, the implementation of policies for renewable energy generation full protection of the acquisition. Promote clean low-carbon energy sources priority access. Encourage waste heat, shallow geothermal and other clean energy sources for heating. Strengthening the CBM (coal gas) utilization, in an orderly bulk coal in key areas of governance, the implementation of biogas projects.
The implementation of comprehensive improvement of coal-fired boilers. The promotion of clean and efficient coal-fired boiler, strict implementation of coal-fired boiler emission standards. The region above the county level cities and built-up area basically eliminated 10 tons of steam per hour coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal-fired facilities, in principle, to a new 35 tons of steam per hour coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers. Ambient air quality did not meet the city should increase efforts to eliminate further. Key areas basically eliminated 35 tons of steam per hour of coal-fired boilers, 65 tons of steam per hour and above all coal-fired boilers to complete the transformation of energy-saving and ultra-low emissions; low nitrogen gas boiler basically completed the transformation.
In the region the implementation of ultra-low emissions and energy-saving coal-fired power plants, encouraging "Wu - Chang - Stone" to carry off white smoke fired power plant pilot area. Before the end of 2019 to complete the "Wu - Chang - stone" "Kui - ultra-low emissions and energy-saving black" area, and Korla Ili River Valley and surrounding areas with the transformation of the conditions of coal-fired plants, in other areas before the end of 2020 - only carry out. Gradually shutting down key areas do not have the conditions for the transformation of highly polluting coal-fired power plants.
Over the next three years, the Xinjiang region will strictly implement the Plan of Action to win the Battle of Blue Sky, "the Wu - Chang - stone" "" Kui - alone - Ukraine "and other key areas as the main battlefield, promote industrial structure, energy structure, transport structure adjustment and optimization, strengthening regional joint prevention and control measures to deal with weather and heavy pollution, further clarify reduce the concentration of PM2.5, and significantly reduce the number of heavy pollution days, significantly improve air quality, enhance the blue sky happiness of the people make unremitting efforts.Free Chat
