Industrial boiler water quality standard industrial boiler water quality standards, the new range of water quality standard industrial boilers This 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 1t diesel steam boiler ukraine steam boiler water as a medium is also applicable to a given water as a medium pressure hot water boiler 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.
Since this year, Qingyang City, Gansu Province Environmental Protection Bureau to continue to improve air quality at the core, in order to implement the Air Pollution Control Act as the main line, adhere to the rule by the people, source control, increase the comprehensive management of air pollution, construction of accurate and efficient and fine air pollution comprehensive prevention and control system, to fight air pollution control tough fight.
Qingyang Xifeng Kowloon City Road, South Street neighborhood community coal-fired boilers in accordance with the "clear" work requirements, continue to increase coal-fired boilers "cleared" efforts, multi-pronged, comprehensive treatment of the families of Xifeng Animal Husbandry Bureau building coal-fired boilers were removed.
Since coal-fired boilers to carry out "clear" its work, Kowloon South attaches great importance to the community, seven coal-fired boilers within the jurisdiction of actively deployed, timely follow-up, held a special arrangement will, continue to strengthen measures. In the community workers and urged many times to persuade, the District Animal Husbandry Bureau family member courtyard boiler successfully removed. After removal of this coal-fired boilers, coal-fired boiler demolition community task has been completed.
Phase out coal-fired boilers is an important measure to improve the air quality of the environment, but also the strong expectations of the masses. The demolition action, and effectively promote the area to carry out "the image of the city, the level of management" to work for the creation of a national civilized city to make its due contribution.
8 tph WNS series condensing gas-fired 1t diesel steam boiler ukraine project for food industryIn food processing enterprises, steam boilers provide a stable heat source for the baking and frying, high-temperature sterilization of food ingredients. Sichuan Aning Food Co., LTD. is a snack food enterprise which mainly manufactures sauce and halogen food.In recent years, Aning Food has shown a rapid development trend. The original boiler equipment has not been able to meet the current production scale. Therefore,the company is urgent to purchase steam boilers. With the excellent quality and excellent performance of the WNS series steam boiler, ZOZEN won the trust and favor of Aning Food and customized the steam boiler system for the company. WNS series gas-fired steam boilers adopt the design of large-diameter corrugated furnace to enhance the smoke disturbance and effectively improve the heat transfer effect of the furnace. In addition, the threaded tubes developed by ZOZEN has advanced manufacturing technology, and the heat transfer coefficient is 1.2 times higher than that of the ordinary tubes. With the condenser added at the tail of the flue, the thermal efficiency of the boiler can be as high as 98% or more. Moreover, this series of steam boilers has both high product and environmental protection performance, and can easily achieve NOx ≤ 30mg/m³ , realizing the unification of economic benefits and environmental benefits.
Electric 1t diesel steam boiler ukraine heated by resistance heating resistance heating, electric heating means is a steam boiler using resistive heating element for heating the tubular. Electric heating steam boiler is structurally easier superimposed combination, and the control flexibility, easy maintenance and replacement. Currently electric boiler basically using resistive heating element for heating the tubular electric boiler. Electromagnetic induction heating means, by the magnetic energy into electrical energy, and then the steel member is heated to a magnetic induction, a heating generates heat. Electric heating source is steam boiler electric boiler heating system, the heat medium is water, the use of electricity valley difference, at low power, electric heating timely open the steam boiler, the water in the tank is heated, heat, storage, backup power to peak time then. When the power supply peak power of peace, the need for timely close the electrically heated steam boilers, hot water heating continued storage tank, so as to save energy.
