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 Do not meet industrial policy access, industrial layout planning, outdated equipment and technology, and no hope of treatment compliance, implementation of the "two off three clear"; the inclusion of the relocation of integration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.

4 tph WNS series condensing gas-fired steam boiler project for universitiesFounded in 1958, Changchun University of Science and Technology has three campuses with a building area of 627,000 square meters and a total of 29,820 students. Therefore, the boiler plays a non-negligible role in ensuring the daily needs of teachers and students.Facing the severe situation of environmental protection, Changchun University of Science and Technology decided to upgrade the original boilers. ZOZEN won the trust of Changchun University of Science and Technology with its advantages of safety, efficiency, environmental protection, energy saving and rich experience in boiler projects. In order to fully meet the needs of the university, ZOZEN customized a branch of WNS series gas-fired steam boiler systems. In terms of safety, ZOZEN has a complete and strict quality inspection process, fundamentally avoiding hidden dangers of quality, meanwhile, more than ten kinds of safety protection interlocking devices such as the failsafe interlock of burners to ensure the safety of the boiler during operation. In terms of environmental protection, WNS series natural gas fired boilers adopt self-developed combustion optimization control technology, combined with advanced low NOx combustion devices, effectively controlling NOx emissions below 30mg/Nm³, which is in line with environmental requirements. In addition, in order to achieve better energy-saving effect, ZOZEN installed energy-saving devices on the tail of the boiler flue, so that the thermal efficiency of the boiler can reach as high as 98%.

Different types of gas steam boiler structure and technical characteristics: Boiler manufacturing industry gradually been improved and developed in trial and error, now on the market boiler, gas steam boiler classification clear, but many users new to the boiler for the boiler structure and technical characteristics less clear, fast boiler for your brief gas steam boiler several representative.

Objective analysis: strengths and weaknesses gas boiler: increasing energy crisis and the growing environmental pressures, the Chinese government also introduced a series of laws and regulations on the promotion of energy conservation and emissions, encouraging the use of new energy and other areas, gas boilers should be shipped together, breaking the previous coal-fired boiler "thriving" situation.
