10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.
"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.
In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).
It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration.

Circulating flow rate is an important index to ensure the safe and stable operation of china condensing boiler manufacturers. The circulation flow rate is too low, it is easy to cause boiler overtemperature shutdown, even internal riser part of steam production is serious. But the circulation flow rate is too big, the boiler resistance increases, has increased the circulation pump power consumption. It is concluded through practice that the actual circulating flow rate of the boiler should be 1.2 × 1.4 times that of the designed flow rate in overloading operation. How to ensure the circulating flow rate of the overloaded boiler? On the one hand, it is necessary to do a good job of hydraulic adjustment in the boiler room. In the initial stage of operation, the FBL ultrasonic Flowmeter is used to test and run the boiler water, and if the water is insufficient, the reserve needs to be adjusted. Boiler and economizer water until the operation of boiler water up to 1.2 to 1.4 times the designed circulation. On the other hand, reduce boiler resistance. In the process of boiler installation, the pipe diameter of boiler inlet and outlet pipe is enlarged appropriately, the resistance from boiler to boiler room is reduced, the outlet and return device in furnace is checked, and if the resistance is too large, the reconstruction is carried out through consultation with the manufacturer. Through these two methods, the circulating water quantity of the boiler is guaranteed, and the safe operation of the boiler under overload is guaranteed.
If you do not know how to operate steam china condensing boiler manufacturers:
Method one: find a boiler operator to help, and of course, you will pay for it.
Buy gas china condensing boiler manufacturers boiler manufacturers to pay attention to what is undeniable, professional gas boiler for many years to maintain the excellent quality but also allows more users start using it had a greater interest, at the same time it led people to identify the quality of the gas boiler become more care and attention. However, if we find the right gas boiler equipment is required at the time of purchase to focus on the following aspects. 1, in fact, concerned about the quality of boilers in most cases, the user has a certain thinking skills at the time of purchase safe and reliable gas boiler plant will first focus on one aspect of quality is its boiler, and this can be provided from the merchant's product information honor and out in a good evaluation, on the other hand has a gas boiler performance characteristics and core technology can reflect the intuitive quality is excellent. 2, attention to boiler cost can be sure that one aspect of the cost of gas boiler is also in the purchase should focus, because of the high cost of boiler equipment must be both excellent quality and affordable price advantages of these two features, and benefits of such a choice is not only allows users to feel the real value for money, but also to avoid the gas boiler users how many of these problems than expensive coal-fired generating more questions. 3, focus on customer word of mouth In addition, everyone in the choice of a good gas boiler Shihai should refer to previous customers' specific evaluation of this device, and the content can actually get access to the boiler brand's official website, then we can by true evaluation of these past clients to professional boiler equipment for gas, easy to use, and security and other aspects of embodied get a comprehensive understanding of, and then also be able to find a better reputation boiler equipment as soon as possible. All in all, from several aspects described above, start selecting a better quality of the gas boiler equipment is also relatively more practical approach, of course, worth to learn and use. But apart from these, the better choice for such a device should also be oven gas boiler which brand good or good is what manufacturers and other problems.
