the main features of a water tube boiler

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.

In view of the use of the burner, the air supply system is the best embodiment of the gas the main features of a water tube boiler, the air supply system, must pay attention to air flow, air and other details, particularly in the light housing, the motor and the associated wheel, excellent results Therefore, when using gas-fired boiler, the overall effect of highlighting the advantages of maturity is a very sensitive topic.

4 tph WNS series gas-fired fire tube the main features of a water tube boiler project for chemical industryIn the manufacturing process of all kinds of chemical auxiliaries, the key process of concentration needs steam support produced by steam boilers, which direct affect the quality and performance of chemical auxiliaries. Jiangsu Han Kuang Industrial Co., Ltd. has become one of the national largest production bases of petrochemical auxiliaries. With a sudden increase in market demands, Han Kuang Industrial decided to introduce a branch of equipment that equipped with automation systems to accelerate the intelligent transformation of environmental protection and safety. Han Kuang Industrial planned to purchase environmental friendly and high efficient steam boilers featuring automatic and safe operation. After a series of careful and rigorous market research, Han Kuang Industrial reached cooperation intention with ZOZEN and ordered 2 sets of 4 tph WNS series condensing gas-fired boilers (WNS4-1.6-Q). The full automatic intelligent control ensures the long-time safe and stable operation of boilers, which save a lot of operational and maintenance cost  for Han Kuang Industrial. More than that, this series of gas-fired steam boilers is ZOZEN typical energy-saving and environment-friendly product. The large-diameter corrugated furnace in conjunction with the advanced low NOx burner can easily reduce the NOx emission below 30 mg/m³; at the same time, ZOZEN engineer equipped energy-saving devices on the flue tail of the boiler to reduce the exhaust gas temperature to 60 degrees, enabling the thermal efficiency up to 98%. The boiler complied with the concept of energy conservation and environment protection as well as providing the enough heat source that production line needs.

4, high and low temperature hot water the main features of a water tube boiler pressure water supply Jieke.

Only low pressure hot water boiler supply water temperature is less than 100 deg.] C.

5, pressure boiler circulating pump hot water heating systems, pumping systems engineering is sent to the boiler return water, is generally used in water pump. It has to overcome the resistance of the systemic circulation, but also to maintain a certain pressure boilers, boiler water at high temperature to ensure that no vaporization.
