35 tph SZS gas-fired water tube boiler project for dairy industryPlenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable 1 20 ton fired steam boiler has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environmental policies to improve the air environment. Feihe Dairy is taking an active part in environmental protection, the company decided to replace the present 2 sets of 35 tph coal-fired steam boilers and one set of 20 tph coal-fired boiler with 3 sets of 35 tph gas-fired steam boilers. Considering that the steam boiler is a core equipment of the production line, the company had attached great importance to this purchase and held an open tender. ZOZEN successfully won the bid with excellent product quality and service, and provided the company with 3 sets of SZS series gas-fired steam boilers. This series of boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body. In addition, to effectively reduce the NOx emission, the boilers are equipped with large volume furnaces and advanced low NOx burners imported from Europe.

Why condensing boiler sales will increase every year? Under the influence of the modern concept of energy saving in the purchase of products like heating is more popular in condensing boilers, statistics confirmed that showed sales rising year by year in the state during the years of research and development come out of condensing boilers. So why year after year of rising sales of a full range of condensing boilers do? We will be analyzing the reasons for the rise in sales of condensing boilers below. One reason, can save heating costs are well known in the modern condensing boiler has not yet come before people in many parts of the device only by means of conventional boiler when heating is influenced by the principle of cause conventional boilers spend a lot of energy to release some heat . But they have very different condensing boilers and conventional boilers in the design and working principle of the above, the use of modern release can save heating costs on top of a relatively large amount of heat condensing boiler to a certain extent. Two reasons, can reduce the frequency of replacement of modern heating equipment currently on the market of raw materials existing ordinary boiler product is mostly copper, after long-term use of corrosion and thus vulnerable to a series of failures to be replaced. Condensing boilers produced material was stainless steel, even if the contact during operation of the steam does not affect their quality will be able to make virtually modern replacement frequency heating apparatus is controlled. Class three reasons, the release of a very small amount of nitrogen oxides during the operation most of the conventional type boiler in operation of heating equipment are required to coal-derived material as a raw material, coal or the like at the time of combustion of the material will release a large ships harm air quality material composition. While condensing boiler during operation of the steam is produced after combustion of natural gas as a raw material, and therefore the operation at the time of release of the content of nitrogen oxides is much lower than a predetermined standard. Analysis of the reasons condensing boiler sales rising year by year made temporarily come to an end. Through the above three reasons we can have some understanding of the advantages of using credible condensing boiler from the side, I believe that with these advantages condensing boiler different from the ordinary boiler heating equipment will continue to grow in future sales.

Oil-fired boiler safety instructions oil-fired boiler is one of many hot water boiler to one of how to prevent boiler fuel boiler appears to be abnormal use it? First, to ensure the normal operation of the fuel in the boiler feed water quality and quality of qualified soda, to reduce the water wall tube fouling and corrosion, strengthen supervision and boiler water boiler water when found unqualified, should increase the number of times a given row; while the flue gas flow rate control , especially when the flue gas velocity in the corridor, during installation and servicing, should minimize the distance between the wall and the superheater tubes, while the distance between the tubes to uniformly as possible. second, the fuel boost heating boiler carried out in strict accordance with procedures, control the speed boost. were lower header sewage water wall work required to build the water cycle as soon as possible, promptly switched the gun to ensure uniform heating surface is heated to eliminate half of combustion, eliminating thermal excursions. third, do a good job adjusting fuel combustion boiler, the flame deflection preventing, controlling coal fineness noted that, with a reasonable air to prevent coking, reduces thermal excursions, to prevent the tail reburning fuel boiler; boiler steam parameters be closely monitored, and the main indicators of the amount of water evaporation and the like, to prevent pressure Release, full of water, water accident. fourth, strengthening sootblower sootblower and management, serious fouling preventing heating surface, when there is found furnace coking phenomenon, should be increased blowing Gray times, ensuring good water wall heat sink; overheating problem of the presence of long-term heating surface, installation of thermal supervision controlling temperature measuring points; expansion to ensure accurate indication means using oil-fired boiler units must be fully taken into account the safety problems. in the inspection process must be meticulous in place. to ensure the personal safety of the unit.

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.
