china automatic wns horizontal 3 pass steam boiler
In many processes in paper mills, boiler applications are required. The paper industry uses wood, straw, reed, rags, etc. as raw materials, which are separated by high temperature cooking to form cellulose, which is then bleached, diluted, shaped, pressed, dried, and made into a series of processes. . The use of china automatic wns horizontal 3 pass steam boilers is inseparable in these processes.
After the gas boiler by long-term use, it will accumulate a certain degree of scale and impurities, which may be a water treatment system to aging or regular maintenance work is not in place. When the impurity rises, leads to clogging of the boiler pipes, the heat dissipation is poor, the probability of the boiler will squib. If water boiler slag formed irregularly discharging furnace, the clogging of the tubes will cause tube rupture. But also reduces the heat transfer.
Recently, Henan Province issued the "2019 Henan ecological ideas and points", as follows.
1, the implementation of "winning Blue Sky Battle three-year action plan," "Henan tackling pollution prevention three-year action plan." We continued to do a good job in controlling coal, discharge control, train control, oil control, dust control, control burn "six control" based on the prominence of coal consumption reduction, optimize the industrial layout, transport restructuring, diesel trucks governance, urban dust remediation industrial upgrading green, clean heating construction, ecological expansion speed, enhance monitoring capacity, heavy pollution 10 iconic battles weather control and so on.
2, 2019 to promote the implementation of planning, environmental impact assessment and other "unified" requirement, in principle, then add the non-power sector coal consumption province-wide project to promote the transformation of shutting down coal-fired units and behind the irrational total of 1.5 million units kilowatt. Promote political urge the main town of coal units cleared and the main city of Luoyang coal units basically cleared. Do a good job clearing the continuing dynamic "scattered dirt" comprehensive improvement of enterprise and small coal-fired boilers. Township units continued to carry out an intensive investigation, the implementation of inventory management, network monitoring, inspections normalization mechanism, to treat small coal-fired boilers, found together with the ban.
3, already verified "messy dirty" business, in accordance with the principles of the rule after the first stop, the implementation of classification prosecuted. Do not meet industrial policy access, industrial layout planning, outdated equipment and technology, and no hope of treatment compliance, implementation of the "two off three clear"; the inclusion of the relocation of integration classes, in accordance with the principles of large-scale development, relocated to the industrial park and the implementation of upgrading; upgrading the inclusion of the class, set the industry benchmark, the implementation of cleaner production transformation, to raise the overall level of pollution abatement.
4, advancing the steel, aluminum depth treatment with carbon, cement, glass, coke, aluminum and other key industries. Deepen industrial enterprises fugitive emissions control, industrial furnaces special treatment, comprehensive treatment of industrial boilers, foundry industry depth governance, strengthen the petrochemical, chemical, packaging, printing, industrial painting and other key industries of volatile organic compounds pollution.
3.Production of high quality steam
External treatmentis the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the boiler system in question.
